devg-pxa250 driver & 800x600 graphics mode

Hi,

What is a max. resolution supported by devg-pxa250 driver?

Is it possible to obtain 800x600x8 mode for example?

Thanks,
Jacek

Hi Jacek,

I already tried it with that kind of resoultion.
It should support every resolution from the pxa250.

Thank you Sascha for fast reply,

One more question. Did you have any serious problems during graphics
driver starting procedure?

Jacek

The only problem I ever had is the timing stuff for the display.
The photon graphics driver works just fine for me.

Keep in mind, if you use this kind of resolution, you will lose realtime
performance
based on the architecture of xscale.

Hi Sascha,

I have just prepared cables, LCD and all files required for embedded
Photon start.
This is a part of my Photon startup script:

echo Starting Photon…
Photon

echo Starting phfontFF manager …
phfontFF -b300K -d /photon/font_repository -c 20K -j -s 200K

echo Starting io-graphics …
io-graphics -g800x600x8 -dl devg-pxa250.so -amode=/photon/config/pxa250.conf

Let’s assume that all enviroment variables like PATH, LD_LIBRARY_PATH,…
are set properly.
During starting procedure I get the following error message:
dlopen("") failed: Shared library is corrupted

What does mean?

The io-graphics manager loads into memory below components:
40970 1 bin/io-graphics 12r SIGWAITINFO 96K 24K
8192(132K)*
ldqnx.so.2 @ 1000000 352K 16K
libgri.so.2 @ 105c000 44K 8192
gri-photon.so @ 1069000 28K 4096
libphrender.so.2 @ 1071000 180K 8192
and fails at devg-pxa250.so execution.

I also attached output from sloginfo utility:
Time Sev Major Minor Args
Jan 01 00:00:03 1 8 0 phfontXX started OK - EOK
Jan 01 00:00:03 1 8 0 MainLoop
Jan 01 00:00:03 2 8 0 Unable to open phfont.so DLL
Jan 01 00:00:03 5 8 0 Plugin gri-photon.so opened successfully
Jan 01 00:00:03 2 8 0 Failed to init device 0: No mode funcs

Is “Failed to init device 0” info printed by devg-pxa250 graphics driver?
Should I also do some additional settings in IPL/startup except
GPIO pins configuration (LCD controler)?

Thank’s,
Jacek

Without space I get the following error message:
Process 49162 (io-graphics) terminated SIGSEGV code=1 fltno=11 ip=010a6b9c
mapad
dr=00002b9c. ref=00000004

sloginfo reports this time:
Time Sev Major Minor Args
Jan 01 00:00:08 1 8 0 phfontXX started OK - EOK
Jan 01 00:00:08 1 8 0 MainLoop

Jan 01 00:00:13 5 8 0 Opened photon connection:
Jan 01 00:00:13 1 8 0 Received terminate request, exiting - EOK

What is a reason of the io-graphics termination?

Jacek

I think that you can’t have a whitespace between -dl and library name, try
… -dldevg-pxa250.so …

Problem solved :slight_smile:.
