io-graphics returns errno 5
Hi all,
I am trying to set up a QNX system with a GUI. When I try to start up io-graphics during the boot process, I get the
following error message using sloginfo:
Feb 25 08:06:42 1 8 0 phfont.so: init...
Feb 25 08:06:46 1 8 0 phfont.so: initialized.
Feb 25 08:06:47 1 8 0 phfont.so: '/dev/phfont[<32|64>]' server installed.
Feb 25 08:06:47 6 8 0 devg-imx35: 2D HW accel: 1
Feb 25 08:06:48 2 8 0 io-graphics: gf_dev_attach('/dev/io-display/0000,0000,0'): gf errno 5
io-graphics: gf_dev_attach('/dev/io-display/0000,0000,0'): gf errno 5
The file does exist:
# ls -l /dev/io-display/
total 0
crw-rw---- 1 root display 0, 1 Feb 25 08:06 0000,0000,0
but no /dev/phfont* files exist
I have repeated this with DL_DEBUG set to 1, but there seems to be no useful information around the error message :
----8<-------8<------------------

----8<-------8<------------------
I get errno 5 when I call io-graphics for the first time after reboot. If I call it a second (or more) times, I always
get
crw-rw---- 1 root display 0, 1 Feb 25 08:06 0000,0000,0
# io-graphics -vvv -c /etc/system/config/display.conf
io-graphics: gf_dev_attach('/dev/io-display/0000,0000,0'): gf errno 2
from now on. But /dev/io-display/0000,0000,0 is still there, with the access rights unchanged.
The way I try to start the GUI is:
io-display -c /etc/system/config/display.conf -v -dvid=0,did=0
waitfor /dev/io-display 10
Photon
waitfor /dev/photon
io-graphics -vvv -c /etc/system/config/display.conf
Any ideas?
Thanks
Bernd

RE: io-graphics returns errno 5
Are you sure the file system is consistent at the time your are first trying to start io-graphics, or some script is not
trying to mistakenly start io-graphics twice?
What do the contents of your display.conf look like? How are you starting io-display?

Re: RE: io-graphics returns errno 5
Hi,
my first attempt to get the GUI running was to enter commands which I mentionend in my original post from the command
line of the console. Since it did not work, I tried to put them into the startup script (*.bsh file of the system
builder project), but the result was the same.
When I boot without the GUI commands in the startup script, there is no process called io-display shown by pidin. There
are no other startup scripts.
Is there a way to check the file system is consistent besides waiting for some seconds before starting the drivers
manually and checking that there are no error messages displayed by sloginfo?
BTW, I start several other drivers like network, I2C, audio and USB earlier in the *.bsh script; they work without any
issues.
The content of display.conf is
# cat /etc/system/config/display.conf
device {
drivername=imx35
vid=0
did=0
modeopts=/etc/system/config/imx35.conf
display {
xres=800
yres=600
refresh=60
pixel_format=rgb565
}
}
I start io-display using
io-display -c /etc/system/config/display.conf -v -dvid=0,did=0

RE: RE: io-graphics returns errno 5
OK, I missed the point about starting from the command line. If starting from the command line does not work, then
there is most likely another problem.
Let us forget Photon for now, and concentrate on GF.
Start io-display.
Then try to just run egl-gears, do you see anything, or get an error?

RE: RE: RE: io-graphics returns errno 5
Did it actually print:
gf_dev_attach():No error ?
Run it in the background, egl-gers &, then type:
pidin > out.txt
slay egl-gears
post out.txt
get the output of 'sloginfo':
sloginfo > slog.txt

Yes, I have pasted the output from the console to my posting. egl-gers returns immedeately, there is no way for me the
start pidin while it is running:

But I get

RE: RE: RE: RE: io-graphics returns errno 5
If you run egl-gears as:
egl-gears > /dev/null &
then you can get the pidin output. If you are not seeing something on the display, then this points to something being wrong with the GF setup/driver.
