I just installed QNX rtp 6.0, and am having video problems. Have
searched the Knowledge base, but could find no pertinent answers.
SYMPTOMS:
Photon runs in VGA mode, with only 4-bit color and 640x480 – no other
options can be selected (Standard VGA mode and driver)
I also get, at boot, a message
“Unable to open device /dev/par1 (no such file or directory)” –
not sure whether this is related or not
WHAT I HAVE TRIED:
Pulled the board and confirmed it is a SGS Thomson, NVidia Riva 128
did “pci - v”, and got: (probably overkill, but here it is)
Class = Display (VGA)
Vendor ID - 12d2h, NVidia / SGS Thomson
Device ID = 18h, RIVA 128 Riva 128 2D/3D GUI Accelerator
PCI index = 0h
Class Codes = 30000h
Revision ID = 10h
Bus Number = 1
Device number = 0
Function number = 0
Status reg = 2b0h
Command reg = 7h
Header Type = oh Single-function
BIST = 0h Built-in-self-test not supported
Latency timer = 40h
Cache line size = 0h
PCI Mem Address = fd000000h 32-bit length 16777216 enabled
PCI Mem Address = f6000000h prefetchable 32-bit length 16777216
enabled
Subsystem Vendor ID = 10b4h
Subsystem ID = 1b1bh
Max Lat = 1ns
Min Gnt = 3ns
PCI Int Pin = INT A
Interrupt line = 9
Capabilities Pointer = 44h
Capabilities ID = 2h
Capabilities = 10h - 4000001h
Next, I looked in the /etc/system/enum/devices/graphics and ensured
that there is a line which matches the vendor ID and Device ID
information. It looks like it should call
devg-iographics once for devg-tnt.so
and then
devg-vesabios.so
So far, everything looks like it should be working, IMHO.
Next, I exit Photon and try
crttrap trap
and I get the following 3 lines just before my system completely hangs
/usr/photon/bin/devgt-iographics -dldevg-tnt.so -I0 -d0x12d2,0x0018
Memory fault (core dumped)
/usr/photon/bin/devgt-iographics -dldevg-vesabios.so -I0
-d0x12d2,0x0018
Seems the vesabios.so driver is crashing – any ideas??

Not sure if you got the other problem fixed or not…
“Unable to open device /dev/par1 (no such file or directory)”
I had the same problem a fixed it by changing the BIOS settings for my
parallel port. Mine was set to auto so I changed it to a fixed value (IRQ 5
or something). Give that a try.
