phfont and io-graphics problems

QNX DEVELOPERS Realtime and Embedded
1

Hi, I have seen a similar problem mentioned in the discussion forums (posted by - iangibb). I am building an embedded system with a SH4 using QNX 6.3. When I run the io-graphics command I also get the same error as the user iangibb, however as far as I can tell All the environment variables and dll’s are present. Can anyone suggest what might be missing?

[color=green]# io-graphics -dldevg-coral.so -g640x480x8 -d0x10cf,0x2019
Fatal error - check sloginfo.

Process 8200 (io-graphics) terminated SIGINT code=0 by process 1 value=0.

Thanks in advance,

Do you have the latest SH4 critical patches? From the last notice:

SH4 ARCHITECTURE - PROBLEM IMPACT:

This problem affects drivers that perform non-cacheable mappings of anonymous
memory for DMA (examples include USB and networking), or allocate memory buffers
shared with applications (examples include audio). Possible symptoms range from
data-buffer corruption to random driver faults. Observed symptoms, in the case
of USB, were the crash (through a SIGSEGV) of the USB stack during initialization;
in the case of audio, the symptom was typically periods of silence in the playback
stream.

Thanks Rick,

The patches fixed some USB issues I had and fixed some strange crashes when using ls -al in /dev/…

I think that the io-graphics engine is working now (at least no more errors) - it turned out that I had not set:

setconf CS_LIBPATH /proc/boot:…etc…
