post122589: Is web browser development only available in SDP 7.0?

Peter Mattsson — Wed, 07 Aug 2024 17:38:13 GMT

I'm interested in testing some QNX Web Browser 2.0 development (https://www.qnx.com/developers/docs/7.0.0/#com.qnx.doc.blink.browser/topic/browser_about.html). But the Web Browser package is not available for neither SDP 7.1 or 8.0, which is the only versions I have license for.

Is it possible to get the Web Browser package separately in some way? Or do I have to get a 7.0 license and install that locally first?

post122588: Re: QNX SDP 8.0 Installation is failing

Peter Mattsson — Wed, 07 Aug 2024 12:43:10 GMT

Ok. So... after starting **virtqemud** and **virtnetworkd**

    sudo systemctl start virtqemud.socket

    sudo systemctl start virtnetworkd.socket

And then adding this to the **Extra Options:** field when creating the virtual environment

    --ssh-ident=prompt

It now works like a charm.

I also enabled **virtqemud** and **virtnetworkd** to make those services start at  boot.

    sudo systemctl enable virtqemud.socket

    sudo systemctl enable virtnetworkd.socket

post122579: Re: QNX SDP 8.0 Installation is failing

Peter Mattsson — Tue, 06 Aug 2024 13:39:58 GMT

Not a complete answer. But at least I gotten the network to work. What I needed to do was to make sure **virtqemud.socket** and **virtnetworkd.socket** was running before creating the virtual target.

I did this by running these lines before creating the virtual target.

    sudo systemctl start virtqemud.socket

    sudo systemctl start virtnetworkd.socket

After that I can log onto the qnx virtual machine with ssh by using the ip address on the **virbr0** adapter which is automatically available after starting **virtqemud.socket** and **virtnetworkd.socket**

The login on qnx is in this case **root** with the password **root**

    ssh root@192.168.122.179

But I still get "Invalid target settings" in the Momentics IDE, though. And trying to run the code on the virtual target gives me a dialog box saying "Target is not connected: vm1".

So if anyone has any answer about what settings might be wrong and how to connect my project to the virtual target, that would be highly appreciated.

post122568: Power-Safe filesystem (qnx6) -- how to prevent writing to files as root user?

Piyamate Wisanuvej — Thu, 18 Jul 2024 17:07:11 GMT

I want to make some files on my hard drive read-only, even by the root user. This is to prevent root user from changing some credential-related files such as /root/.ssh/authorized_keys and /etc/shadow.

On Linux with ext4 filesystem, you can make files read-only (immutable) to all users including the root user by using command: chattr +i [filename].

I'm looking for the same functionality on Power-Safe filesystem (qnx6) on QNX 7.1. It looks like fs-qnx6 does not support such "immutable" attribute based on the documentation https://www.qnx.com/developers/docs/7.1/#com.qnx.doc.neutrino.utilities/topic/c/chattr.html.

I already tried setting permission octal value to 400 -- read-only by file owner, but it does not prevent writing as a root user.

```

# mount

/dev/hd0t179 on / type qnx6

ifs on / type ifs

# pwd

/root

# echo "original" > test.txt

# cat test.txt

original

# chattr +i test.txt

chattr: 'i' - Unknown filesystem option

# chmod 400 test.txt

# ls -l test.txt

-r-------- 1 root root 9 Jul 18 16:45 test.txt

# echo "modified" > test.txt

# cat test.txt

modified

# ls -l test.txt

-r-------- 1 root root 9 Jul 18 16:46 test.txt

```

post122567: Re: QNX SDP 8.0 Installation is failing

Peter Mattsson — Wed, 17 Jul 2024 10:11:45 GMT

I have similar problems.

I ran the "check-net" script supplied with SDP 8 before creating the Qemu x86 vm (if you read the output when creating the vm it will actually tell you to run this script and the path to it. It will create a br0 adapter for you)

The vm is created successfully and a terminal is opened into the vm in the IDE. But there is something else wrong since my projet still can't connect to the vm (can't find correct IP address). My guess is that there is some additional configuration to the br or the tap adapter needed. Or maybe something to the vmnet adapter inside the QNX vm?

I have the same fault as you when trying to create an aarch64 vm.

I'm using EndeavorOS Linux (Arch derivative)

I was trying to bring up a new machine for QNX 8.0, while creating the target using qnxmomenticside, it failing to create in both x86-x64 and aarch64le.

The error which I am getting in x86-x64 is unable to determine location of bridge.conf from /usr/lib/qemu/qemu-bridge-helper.

So, how can i use TSC-Deadline mode along with local APIC timer on the X86 platform?

Hello,

I have tried to run python 2.7.3 on QNX 6.5.0 over arm-v7. If I comment the "_reset_cache()" function I can run some tests of the ctypes module.

I get memory fault when I run callbacks and pointers tests.

I think that it is the same problem that you are talking about in the first post. Has someone solved it?

post115109: QNX on Gumstix-Duovero board

Marc Alomar(deleted) — Wed, 25 Nov 2015 12:50:53 GMT

I would like to use QNX on a Gumstix-Duovero board, with an OMAP4430 microprocessor. I've found a BSP for this processor, but it was written for the PandaBoard, which doesn't have the same muxing/devices. So far I've managed to launch U-Boot and to execute the startup code of the QNX image, but the kernel crashes just when the process "procnto" is launched.

I suspect that it might be an issue with the memory (RAM memory is not the same), or with the interrupt lines. Do you have any suggestions about what I should modify on the BSP? Do you think that it is necessary to modify any callouts?

Thank you in advance

post113657: Re: devc-serusb data loss issue

Malte Mundt — Wed, 01 Apr 2015 08:37:02 GMT

Hi Sylvain,

I'm not sure devc-serusb was ever tested with such high bitrates. I assume it is only meant to be used with bitrates up to the highest "native" serial bitrate that is common - 115kbps. But this is just my guess. Have you brought up this topic via QNX Support channels? I highly recommend a CSP (Custom Service Plan) contract with QNX, as with that one you can request QNX R&D to deliver a driver that operates within whatever parameters you specify (as long as the hardware can do it, of course ;-)).

Cheers,

- Malte

post113590: devc-serusb data loss issue

Hi,

When using CDC-ACM ports to communicate between modem device and Nvidia Tegra AP running qnx 6.6, dev-serusb process is losing data packets sent by the modem.

We've probe the usb link with a usb serial analyser, and we see that the modem is sending data to the AP, but the data retrieved by devc-serusb are not correct. the usb driver acknowledges the data packets from the modem, but it not able to retrieve all of them, and to pass them to the devc-serusb process.

The modem data rate on this link is about 6Mbytes/s. Was such an issue observed before? Was devc-serusb ever tested with high bit rates?

Thanks for your support,

Sylvain

post112303: Re: problem with QNX 6.5 and Beaglebone Black Rev C

Dennis Kellly(deleted) — Sun, 09 Nov 2014 01:30:39 GMT

>>> The board keeps rebooting every time

On rev C boards, the reset is due to the watchdog circuit resetting the board after 30 seconds.  It is unlikely eMMC is not the cause of the reset.

The workaround is to hold down the "S2" button while you power up the board.  U-boot reads the S2 switch and performs some alternate processing which seems to defeat the watchdog firing.

You do not need to hold the S2 button if you soft reboot (QNX "shutdown" command).  S2 is required only on powerup.

post112302: problem with QNX 6.5 and Beaglebone Black Rev C

Mehdi Karimi(deleted) — Sat, 08 Nov 2014 20:15:54 GMT

We encountered a problem getting QNX 6.5 onto a specific version of Beaglebone Black(BBB) Rev C.

It seems that there's a BOM change on the 4GB eMMC of the BeagleBone Black (BBB) Rev C.

We got two different BBB: one type with their 4GB eMMCs made by Kingston, and the other made by Mircron.

We can't get QNX running on BBBs having Kingston flash.

We suspect the problem might potentially be driver differences for eMMCs.

Attached is a file of the boot up log captured. The board keeps rebooting every time and goes through the same boot up sequence.

The image of the BBB Rev C with Kingston eMMC is attached.

As Mario said, we no longer support self-hosted QNX Neutrino development systems. You have to install the QNX Software Development Platform on a Windows or Linux host, develop your Neutrino applications there, build an OS image, and transfer it to a suitable target machine. There's a VMware image of a 6.6 machine available in the Download Centre, but it's a sample runtime system that doesn't include any development tools.

post111714: porting QNX into p1005 TWR module

jagan N(deleted) — Mon, 15 Sep 2014 11:54:57 GMT

Hi,

This mail with reference to porting QNX on freescale p1025 twr-module. when I Power ON p1025 twr-module, I could assign IP addr and server IP from hyperterminal for p1025 target board IP and host IP with help of uboot command and I could map qnx build image file also(ie, ifs-p1025twr.raw), but when I boot image file It shows un-read able characters. I  have attached output snap shots for your reference...

We set the value of baud rate in terminal as per standard ---    115200

u-boot version  --- UBOOT (2011.09) (p1025 TWR module).

Serial driver starting in startup script --- devc-ser8250 –e –c384000000 –b115200 0xffe04500,16

The freescale TWR module by default comes with U boot, we just porting QNX build image on top of that. If we change build file as per Qnx document for solving this issue will not be affect after building. The TWR module what we have does not have serial port, we tried to porting using by OTG USB port..what my understanding is what we have twr module does not have RS232 serial port, but we are using for qnx image porting by USB OTG port. so that when Qnx image start it will looks serial terminal driver execution which is not present in TWR module. Is this issue getting this junk characters when its start execution serial driver...?

Best regards,

post108838: RE: mq_open() is not creating unique descriptors

Thomas Haupt — Mon, 17 Feb 2014 09:14:38 GMT

Hi Adlai,

this is expected. Queue descriptors (like all file descriptors) are local to the process that called open(). The mqueue server identifies the client based on the combination of process id and queue descriptor, so there's no problem.

post103738: Running QNX Neutrino 6.4.1 BSP for TI OMAP3530 from u-boot-2010.12

Martin Meiboom(deleted) — Tue, 30 Jul 2013 13:51:46 GMT

Dear fellow QNX developers,

I am running QNX on different Gumstix on a Tobi-Board, since I received newer Gumstix with u-Boot 2010-12 I am not able to load the QNX image.

Here are the changes discovered so far:

In U-Boot 2010-12 the MMC is available under mmc 0 and not anymore under mmc 1.

The mmc init does not allow to load the image into the ram, since fatload doesn’t recognize the mmc. After mmc part 0 fatload is able to detect the partition.But after loading the image into the Ram the Gumstix reboots when calling the address.

The Image does boot without any Problems on a different Gumstix with u-Boot 2010-09.

Are there any sugesstions to be able to run the image, maybe without flashing a new u-Boot?

Thanks in advance

The following tftp command on my QNX target also fails:

Transfer timed out.

My Linux PC (IP=172.17.1.1) connects directly to my QNX target (IP=172.17.16.1), they are not on the real network.

I was able to ping QNX target from my Linux PC, and ssh login to QNX target from my Linux PC.

I was also able to tftp download a file from Linux PC to QNX target, but not the other way around.

So it seems like only the tftp client works on my QNX target, but not the tftpd server.

Yes, I have disabled the iptables on my Linux PC.

# cat /etc/services |grep tftp

tftp        69/tcp

The netstat shows that tftp is enabled:

post98910: tftpd does not work in QNX Neutrino 6.5.0

Jane Sun(deleted) — Wed, 30 Jan 2013 22:34:00 GMT

Hi QNX Support,

I am using QNX Neutrino 6.5.0, and the tftpd does not work.

I have inetd running on my Neutrino 6.5.0 target, and the /etc/inetd.conf has following tftp setting:

# ps -ef |grep inetd

 0 344112 1 - Jan01 ? 00:00:00 inetd /etc/inetd.conf

# cat /etc/inetd.conf |grep tftp

#tftp dgram udp wait root /usr/sbin/tftpd in.tftpd

tftp dgram udp wait root /usr/sbin/tftpd tftpd -s /tftoboot

Since the tftp daemon in Neutrino 6.5.0 is "tftpd" (not in.tftpd), so I replace the "in.tftp" with "tftpd" in "/etc/inetd.conf".

On my Neutrino 6.5.0 target, I have following files under /tftpboot:

# ls /tftpboot/

SDMA_MUTEX inetd.pid sshd.pid test.txt

When I try to tftp download the "test.txt" file from my Neutrino 6.5.0 target to my Linux PC, I got the tftp timeout:

Linux PC$ tftp -v 172.17.16.1

Connected to 172.17.16.1 (172.17.16.1), port 69

Hi pratap,

Compiler tool chain will not be there in your beagle.ifs that is the reason your not able compile your c code...

compilation on the target is possible only if you include the compiler tool chain in your target image,but including

1. Build a hello world application in Momentics with target type as ARM.

2. Copied the binary to the BSP's prebuild/sbin folder

3. Modified the build script to run the binary at start up

4. Rebuild the BSP to get the BSP image

5.Started the board using the image

6.In target while it is trying to execute the binary it is showing the folliwing error -

can't start "XXXXXX" (2)

here "XXXXXXX" is the name of the binary.

Can you please help on this.

post88823: RE: RE: got error while reading from COM 1

Thomas Haupt — Wed, 14 Sep 2011 12:14:27 GMT

Hi,

regarding the baud rate: Yes, of course -- the one you specified in the termios structure and cfsetospeed(), i.e., 9600 baud. It might be a good idea to also set the input baud rate explicitly, using cfsetispeed().

From what I see in the code you provided, your COM port setting should be 9600,N,8,1 (9600 baud, no parity, 8 data bits, 1 stop bit).

You could try running a second instance of 'hyperterminal' instead of VMware, to see whether the serial communication between the two serial comm. ports on your host works at all. If it does, you can advance to using VMware with QNX on one end.

Thomas Haupt — Fri, 09 Sep 2011 08:11:49 GMT

Hi,

to configure a VMware player, follow the steps below. For other VMware products, the procedure should be similar:

- Shutdown QNX within in the virtual machine

- "Power off" the virtual machine ("Virtual Machine" / "Power" / "Power off"). Do NOT exit the VMware player.

- Click "Edit virtual machine settings"

- In the list on the hardware tab, select the serial port (or add a new one with default settings if there isn't any)

- Check "Connect at power on"

- Select "Use physical serial port"

- From the combo box, select the serial port you want the VM to use

- Click "Ok" and start the virtual machine. /dev/ser1 should now be connected to the configured COM port.

Thomas

post88715: RE: RE: got error while reading from COM 1

Thomas Haupt — Thu, 08 Sep 2011 12:53:40 GMT

Well, if you have 2 physical serial ports on your host, it's easy:

- Connect the two ports using a null-modem cable (as you probably already did)

- Configure the VM to use one of the host's physical serial ports (e.g., COM1)

No matter which one you use, it should show up as /dev/ser1 under QNX.

- Run a terminal emulation (e.g., hyperterminal) on the host, and connect to

the _other_ COM port (e.g., COM2).

With that setup, you should be able to both read and write from/to the serial

port in QNX.

Thomas

post88711: RE: got error while reading from COM 1

Thomas Haupt — Thu, 08 Sep 2011 12:04:02 GMT

Ah, right. That'll be the next problem. AFAIK, you'll not be able to exchange data

between the host and the virtual machine in both directions. Depending on the settings

in your VMware, you'll be using:

- either an existing (hardware) COM port of your host, then you cannot use a host

  application to talk to the virtual machine (you'd need to loopback the serial

  port... :-)

- or a file / pipe on the host; in that case, the VM will only be able to write to

  the serial port.

If you need to test bi-directional serial communication in your VM, I think there

is only one option - use a second host and a serial cable to establish a true serial

connection, and configure your VM to attach to the physical COM port.

Thomas

post72631: new Variant name for a library

Guillaume Varlet — Wed, 27 Oct 2010 13:45:02 GMT

Hello.

I'm trying to create a new variant of a library that is accessing some HW either IO or Memory mapped.

The aim is to create a lib IO mapped that will be called library_io.so

On the IDE, I have created a new variant called io on the x86 cpu variant.

I understood that if I want to have the new variant name appening at the end of the library name, I have th comment EXTRA_SILENT_VARIANTS+=io

Then when I build my variant io, the name is library-io.so

That's not so bad, but the library HAVE TO be named library_io.so.

Any chance to exchange the - by an _ ?

Just to make it clear ... these porting steps are OK with the previuos release of ZMQ.

The compilation of the module ctx.cpp of the version 2.0.7 terminates with a cryptic error ... it's a new module and must still be ported.

SOLVED.

The boot script given in project.bld (<bootscript type="mkifs" inline="false">) did not match the one given in the boot image properties. The warning dialog did show an error about a file that could not be found at an absolute position. Resolving this warning caused a update of project.bld. The update also caused an update of the <bootscript type="mkifs" inline="false"> element. It held the correct file after the update.

Is there a way to get warnings shown when building the bootimage. It appears that it is using the file present in project.bld and not the file shown in the properties of the System Builder bootimage.

Does the .ifs image boot if you use a qnx4 filesystem? (Sorry, have to check.) You can use the attached utils to make the qnx4 usbkey from windows. (Read usbstick.txt)

Looks like your are using version 1.01 since the ###'s end in '.' Not aware of any other issues if the .ifs boots on qnx4 filesystem.

Freddy Martens(deleted) — Mon, 15 Mar 2010 22:05:44 GMT

Hi all,

I created a boot image with the system image builder. Named it boot.ifs and copied it to an USB stick prepared with DriveKey.

The following is shown on screen:

f32qldr Version 1.00 (but 1.01 too)

Filename /BOOT.IFS

#############################################.

Image read to address 0x00110000

Transfer control...

Is there something special I need to do with the boot image? The bootimage size is 1.592.236 bytes and 1.593.344 bytes on disk.

Regards,

Freddy

If you only need a custom version of utils/s/shutdown, you can probably

get away with building only that rather than the whole system:

make OSLIST=nto CPULIST=x86 install -C utils/s/shutdown

post46662: Linker Error while building the Neutrino OS/Kernel Source

logeswaran T — Fri, 05 Feb 2010 14:21:06 GMT

Hi,

We modified the shutdown utility of kernel source, to display our own customized shutdown message.

We followed the instruction given in the http://community.qnx.com/sf/wiki/do/viewPage/projects.core_os/wiki/BuildTheOSSource

Steps followed to build,

1. Created a staging directory for installed binaries and headers to go

% cd /home/kernel

% mkdir stage

2. Configured the override makefile stub % cd /home/kernel

% cat >qconf-override.mk

USE_INSTALL_ROOT=1

INSTALL_ROOT_nto=/home/kernel/stage

^D

3. Set the override environment variable to point at the makefile stub

% export QCONF_OVERRIDE=/home/kernel/qconf-override.mk

4. Installed all the Header Files in the local stage

% cd /home/kernel/trunk

% make OSLIST=nto CPULIST=x86 hinstall

5. Built the Neutrino OS binaries

% cd /home/kernel/trunk

% make OSLIST=nto CPULIST=x86 install

But the build stopped with some linker errors as mentioned below.

Dennis Kellly(deleted) — Wed, 27 Jan 2010 02:19:40 GMT

If the original f32qldr terminates with the error <entire program not loaded!>, try the attached binary (version 1.01). Phoenix bios seems to return an error indicator when end- of-file is reached, causing the original to abort. This version ignores the errorcode (assumes success) on the final read.

post45460: Re: f32qldr error

Dennis Kellly(deleted) — Tue, 19 Jan 2010 13:07:28 GMT

There was lots of direct email regarding this failure case.  This post is a summary of the outcome.

Turns out that BIOS returned error (CF on) for the very last cluster read.  The last cluster was partial - meaning a portion of the requested 8 sectors was outside the file as specified by the directory entry.  A version of f32qldr with line 567 changed from "JNC" to "JMP" loaded the .ifs correctly.

It is illogical that BIOS would know anything about the workings of a particular filesystem but that seems to be the case.  Likely work-around is to pad boot.ifs to the next cluster boundary so there is no slack area.

The BIOSs with this reported issue are...

Kontron Board: Phoenix Bios R127 (MODBR127)

FujitsuSiemens Laptop: Phoenix TrustedCore Bios 1.17

Samsung Netbook: Phoenix 07D0

post41199: Problem printing with lpd and serial port

José Miguel del Toro — Tue, 03 Nov 2009 08:23:40 GMT

Hi all,

I want to print to a printer connected to the serial port. So this is how I set up the /etc/printcap file:

imp1:\

:lp=/dev/ser1:sd=/usr/spool/output/imp1:

But when I print with:

lpr -Pimp1 filetoprint

File gets spooled, but the settings of the serial port change! -Like parity checking gets set to "odd", and baud rate to "13" (!). Even if I change the printcap file to look like this:

imp1:\

:lp=/dev/ser1:br#9600:sd=/usr/spool/output/imp1:

Lpd keeps leaving /dev/ser1 in bad state. The spooled fiel print when I change the settings of the serial port correctly with:

stty baud=9600 par=none < /dev/ser1

Any clues on why is this happening? How to fix it?

Thank you!

Jose

Welcome to boost. That is the main reason why I`m not using it. Executable become HUGE! I don`t know about MSM but in general boost is mostly made of template which is why the compile time is so long. It wouldn`t help much to create a library.

It wouldn`t make any difference in executable size (unless you create a shared library)

To help you along, I'll include my "build-hooks" file (I'm assuming you know how to use this) along with a little README file which provides some details on the changes I had to make.

Good luck . . . I wish QNX (are you listening?) would support Python more fully on all their targets (not just x86).

To have a minimum x86 QNX Neutrino system, you do not install it from CD. You use a build file and specify what you need, then use mkifs to generate the OS 'image'. This way, you can have an OS image with a disk space requirement of about 1 - 2 MB, and RAM needed would be below 4 MB.

I am about to embark on building 2.6.2 (or even 2.5 if it's easier) for QNX on arm (6.4.0 and 6.4.1 only support python for x86...grrr).

Any advice...or even any link to your work?

The Neutrino User's Guide says this:

  The names of configuration strings start with _CS_ and are in

uppercase, although getconf and setconf let you

  use any case, omit the leading underscore, or the entire prefix -

provided that the rest of the name is

  unambiguous.

It might be nice if the docs for getconf and setconf said it too...

Glenn Schmottlach — Wed, 03 Jun 2009 16:34:28 GMT

It's libffi which is buried in a Python 2.6.2 build. The Python setup.py script actually runs the ./configure script for libffi. Without my hack, MAP_ANON isn't defined. It's an annoyance that I'd like to understand why it's occurring. I ran into it while cross-compiling Python for x86, SH, and ARM with the ctypes module (see my earlier post on this subject).

unless there is some specific reason not to do so.

Glenn Schmottlach — Wed, 03 Jun 2009 15:50:23 GMT

I'm in the process of building an open source package using GNU's "configure" build process. One file in the project includes mman.h in order to get access to the MAP_ANON definition. Unfortunately, for this build(e.g. ./configure && make), even though MAP_ANON is defined in mman.h it is NOT being defined because apparently __EXT_QNX isn't being defined in sys/platform.h. Looking at mman.h I see the following:

#if defined(__EXT_QNX)

...

#define MAP_BELOW16M 0x00040000 /* allocate below 16M */

#define MAP_ANON 0x00080000 /* anonymous memory */

...

#endif

Looking in sys/platform.h I see the following:

#if defined(_QNX_SOURCE) || \

 (defined(__EXT) && !defined(__NO_EXT_QNX) && !defined(_POSIX_SOURCE) && !defined(_XOPEN_SOURCE) && (_POSIX_C_SOURCE+0 <= 0))

#define __EXT_QNX

#endif

After doing some tests, it appears _XOPEN_SOURCE *is* defined and _POSIX_C_SOURCE+0 <= 0 is *not* true so __EXT_QNX will not be defined during this particular build session.

Can anyone suggest how to force __EXT_QNX to be defined? What in the GNU 'configure' build process could be upsetting these definitions? Who originally sets _XOPEN_SOURCE and _POSIX_C_SOURCE?

Any suggestions would be appreciated. Right now I'm forced to re-define MAP_ANON is the source code instead of relying on the value defined in mman.h. This is an ugly hack that I'd rather avoid.

post30692: Is a QNX port available for ARM for libffi (portable foreign function interface library)?

Glenn Schmottlach — Wed, 03 Jun 2009 14:40:48 GMT

I was wondering if anybody at QNX has looked into supporting the libffi library (see http://sourceware.org/libffi/) on QNX ARM platforms.

This library has been adopted internally by Python in the "ctypes" module and allows you to make calls into 'C' code and even have 'C' code make callbacks back into Python.

After a ***tremendous*** amount of effort, I managed to get Python 2.6.2 compiled under QNX 6.4.0 x86, SH (haven't tested it yet), and ARM. I know QNX supports Python 2.5.2 with the 6.4.0 distro but apparently no one ever tested the 'ctypes' module since it isn't available with the distro. Well, my Python 2.6.2 port *does* support the ctypes module (passes all regression tests) under x86 but seg-faults under ARM:

# python /lib/python2.6/test/regrtest.py -v test_ctypes.py

test_ctypes

test_anon (ctypes.test.test_anon.AnonTest) ... ok

test_anon_nonmember (ctypes.test.test_anon.AnonTest) ... ok

test_anon_nonseq (ctypes.test.test_anon.AnonTest) ... ok

test_nested (ctypes.test.test_anon.AnonTest) ... ok

test_cache (ctypes.test.test_arrays.ArrayTestCase) ... ok

test_2 (ctypes.test.test_array_in_pointer.Test) ... ok

test_byval (ctypes.test.test_as_parameter.AsParamPropertyWrapperTestCase) ... ok

test_callbacks (ctypes.test.test_as_parameter.AsParamPropertyWrapperTestCase) ...

Process 1527858 (python) terminated SIGSEGV code=1 fltno=11 ip=78295168(_ctypes.so@ffi_closure_SYS

V_inner+0x18) mapaddr=00015168. ref=00000004

Memory fault (core dumped)

Looking at the documentation (and code) for the FFI library I see that it's only been verified on ARM Linux. I'm not sure how compatible the Linux ARM ABI is compared to the QNX ARM ABI and I suspect that this might be the cause for my segfault. I know the Linux ARM is expecting a system defined '__clear_cache' function that the QNX compiler warns that it isn't explicitly defined (although it still builds and links).

The subtle differences between the Linux ARM ABI and the QNX ARM ABI is a little over my head. I was hoping a QNX guru might be able to look at the libffi library code (for ARM) and possibly tell me what's missing. I'm asking a lot, I know, but I'm soooooo close to having most of the modules for a completely cross-compiled Python 2.6.2 for x86, SH, and ARM working I'd hate to say I didn't at least try to resolve this issue. Are there any takers at QNX with ARM experience that might be interested in taking a look at this code?

Thanks . . .

For your information, have been using QNX on ESX which support 4 cores per VM. It's a bit painful to install because ESX only support scsi which is not part of the normal install CD. But it's doable. We have a BIG machine running ESX, it currently runs 11 QNX6.4.0 VM, each having 4Gig and 4 cores allocated per VM. There are use as targets to run our applications, not for development. Basically each developer gets it's own VM that is based on our runtime image. The beast has been running for months without a reboot ! Very slick, our IT guy loves it ;-)

Is there any guideline or hint for noobs like me to get boost installed while running QNX in a VM (all x86). Is there a particular place where sources should be placed.

I am using the .iso image and wondering how to get it compiled both on QNX and how to use the library in Momentics IDE.

The only hints I've seen are two posts regarding 1.37 and 1.38, and more related to build (which is the next hurdle for a newbie I guess :).

Any help appreciated..

specify io-blk cache=xxx to devb-eide's command line to minimize the memory used by devb-eide. devb-eide will load io-blk and you can read its document.

cache=total

The total in-memory cache size allowed. Cache memory is allocated as necessary beyond the initial amount specified by the alloc= option until the total size is reached. The memory size uses the suffixes described above; the default is 15% of system RAM.

I've just seen from the docs that it is related to IDE/disk operation but it doubled with number of cores associated via VMWare.. The reason I went for VMWare is because the VPC does not support more than 1 CPU it seems (per target).

Thus the question on HyperV.

It would still be interesting to learn how to minimise the footprint as I would love to test this against low memory hardware.. Any tips or (common numbers even) on reducing the Neutrino footprint appreciated.

M-Systems used to supply a driver for QNX (prior to them being taken over by San Disk). Now that San Disk is running the show I did a quick check to see if I could find any drivers however it does not appear to be any. Your best bet would be to bug San Disk and see if they are willing to recompile the driver for 6.4.0 or possibly hand out the source so you could recompile it.

Before I used pxqldr (which QNX ifs format and PXE API specific!) I spent too many time for grub, because pxegrub+QNX boot loading method was illustraited in QNX docs(Appendix: Advanced Qnet Topics). My vision, there should be note to :

1. pxegrub CARD RESRICTION feature

2. words about pxqldr (or any new will appear) + tftpd restriction (qnx distrib version..search for my post obout it).

You should refer to the foundry project "HMI Framework". This is "official" way. Additionally...

You can extend actionscript by writing your own C code for fscommand2() and geturl().

You can get data (XML format) from a C socket server using the actionscript XMLsocket() object.

You can send data by requesting a cgi URL from your C socket server - the 'tail' of the URL can be the data you want to send.

How does the FLASH program( in form of .SWF) communicate with QNX native pragram in QNX® Aviage® HMI Player ? In other words, how can FLASH program call QNX native C functions?

thank you

Hi,

I'm new to QNX. Whether QNX supports EFI based system (x86). If it so,

where can i get the OS loader for QNX from the EFI shell.

Regards,

Mekas

post16951: RE: Packager utility?

Frederic Plante — Thu, 20 Nov 2008 04:56:20 GMT

We simplified the packaging of BSPs for 6.4, packaging a BSP more or

less means creating an archive with a few metadata files such as

module.tmpl.

See the following in-progress wiki page for details:

Subject: Packager utility?

I notice that the packager utility isn't used to package and distribute

BSPs, and was wondering:

Does this mean tha packager is deprecated?

Is it an inapproriate mechanism for BSPs for some reason?

Is there some other reason it isn't used?

Thanks,

Keith

post16617: New x86 boot methods

Dennis Kellly(deleted) — Sat, 15 Nov 2008 14:39:02 GMT

Two new packages have been added to the Bazaar enabling additional boot options for x86 systems.

1. pxqldr provides a PXE loader (source, binary and documentation) for network boot using typical BIOS support

2. qnxldsys provides a DOS device driver (source, binary and documentation) allowing boot of Neutrino .ifs files directly from DOS bootable media or partition.

You can have multiple senders / receivers on a message queue.

Personally I'd do whatever is easiest since this whole dbus

thing seems a lot like the qnx message bus: attaching to the

namespace to receive messages. The 'correct' port may be to

look at resmgr_attach() and native messaging which mqueue and

AF_LOCAL are based on.

AF_LOCAL performance shouldn't be that bad.  They

share a lot of the same codepath as AF_INET which

we're able to get good performance out of.  Having

said that though local they aren't currently exercised

a lot as they're generally considered more of a

porting aid. Native message passing may be faster

depending on what you're doing.

post15921: Local (Unix domain) socket performance on QNX

Glenn Schmottlach — Tue, 04 Nov 2008 16:15:07 GMT

I have been working on porting DBUS to the QNX Neutrino platform. Since QNX does not support abstract domain sockets, I've opted to use local (Unix domain) sockets which is also supported by DBUS. I have heard that QNX local domain sockets are very inefficient and perform poorly on many targets. Fortunately, DBUS does provide minimal hooks to abstract the transport mechanism and I was considering using the native QNX messaging API (MsgSend/MsgReceive, etc..) as the transport for DBUS on QNX.

Before I undertake this effort, I want to be sure the local domain socket performance on QNX is indeed dismal. Have any QNX veterans had any experiences with it (either pro or con)? Can I realistically expect to see a significant performance improvement using the native QNX services as a transport vs. local sockets? Part of my reluctance in attempting this effort is the fact that it will effectively cause me to "fork" the DBUS code from the development branch which makes it much more difficult to maintain this code with new releases from Freedesktop.org.

post15828: QNX 6.4.0 installer

Hi, I've installed QNX 6.4.0 and noticed that 'software installer' is gone. Previously I used it to install third party software like openssh vim and such. Is there any way to bring the software installer back, or is there any replacement for it?

One of those cases where marketing announcements sometimes get a bit

ahead of development. There just wasn't sufficient customer traction at

the time to justify the development effort.
