Serial Communication between two CPU's
We have a dual board Machine. One of the board gets connected to the network using a LAN wire and the other board gets
connected to the first board using serial communication(COM port).
We have an existing code in QNX 6.2 which is
io-net -dspeedo -dfd fd=/dev/ser1,mac=000102030405,ahdlc -ptcpip
ifconfig en1 / netmask 255.255.255.252
Now we are porting it to QNX 6.5.0
I am trying to create a serial communication like above in QNX 6.5.
I wrote the code
io-pkt-v4-hc -d/lib/dll/devnp-speedo.so -d/lib/dll/devnp-shim.so /lib/dll/devn-fd.so fd=/dev/ser1,mac=000102030405,adhlc
-ptcpip
But the above command throws and error. IT says unable to init the devnp-shim driver. I am new to QNX and i am stuck
with this serial communication problem for the last 3 weeks. I tried almost everything that is available on the internet
but nothing seems to work. We have a release deadline on next tuesday for this. I have ported everything except this
serial communication between these 2 boards is not working. Please help me in solving this.

Re: Serial Communication between two CPU's
Try starting the drivers without specifying the devnp-shim on the command
line. The shim should be started automatically when a devn-* driver is
started.

Re: Serial Communication between two CPU's
I tried but then it says cannot find devnp-shim driver. I think i need to set the Library path.
Please tell me what command shall i run in command prompt for setting library path if my shim driver is in /lib/dll

Re: Serial Communication between two CPU's
Your LD_LIBRARY_PATH should have /lib/dll in it.

Re: Serial Communication between two CPU's
So what can be other reason for this error cannot find Devnp-Shim Driver?
Also like in previous versions of qnx we had multiple interfaces like en0 and en1. Do we have a similar fxp1 and Fxp0
networking interfaces?

Re: Serial Communication between two CPU's
If you just start io-pkt-v4 ddevn-fd ...... does that work?
Yes, you have multiple interfaces fxp0, 1 etc.

Re: Serial Communication between two CPU's
If i run
io-pkt-v4 ddevn-fd -v it runs and throws no error. But when i run ifconfig after running the above command i can see
only one network interface details lo0
But when i put "-" before ddevn-fd and run io-pkt-v4 -ddevn-fd we get an error that
"Unable to load devn-devn-fd.so:Library cannot be found"

You can run either. The hc variant has the security built in.

Re: Serial Communication between two CPU's
I ran this command
io-pkt-v4-hc dspeedo dfd fd=/dev/ser1,mac=000102030405,adhlc -v
It gave no error but when i ran ifconfig i got only one network interface that is lo0.
Then i ran this command by putting"-" before dspeedo and dfd
io-pkt-v4-hc -dspeedo -dfd fd=/dev/ser1,mac=000102030405,adhlc -v
It threw an error
Unable to load devn-speedo.so:library cannot be found
Unable to load devn-fd.so:library cannot be found.
I think LD_library path is not set properly.
Is there a way to set LD_Library_Path through command line?

Re: Serial Communication between two CPU's
You must specify -d¹ before the driver name. What is the output from env¹?
Does it show LD_LIBRARY_PATH?

Re: Serial Communication between two CPU's
export LD_LIBRARY_PATH = /lib/dll
What system are you running on? The LD_LIBRARY_PATH should already be setup
for you. You can see this by running the env command.

Re: Serial Communication between two CPU's
We are running on the system whose BIOS chip has been written by my company. Its a unix based BIOS. So do i have to

I dont have the code for the BIOS chip. Can i set LIBRARY PATH through command line or do i have to request my company
for the BIOS code?
