Hi all,
Has anybody tried to run Photon in 16 bit mode on the XScale PXA 255
target architecture?
When I try to start io-graphics manager with the following options:
io-graphics -g640,480,16 -dldevg-pxa250.so -amode=/photon/config/pxa250.conf
then LCD controller is going to be dead. For example LCD display works fine
in 8 bit mode while the rest of parameters are set to the same values.
Intel documentation says that LCD controller can works in 16bits/pixel mode
with no palette buffer.
How can I disable this buffer or what options should I pass to the
io-graphics ?
Regards,
Jacek
Can you run slogger on the system and post the output of sloginfo after
trying to start io-graphics in 16-bit mode?
Thanks

Hi Michael,
There is the sloginfo output:

Thanks for the output. This is a known issue - the PXA255 16-bit mode runs
in RGB556 mode, while the standard Photon 16-bit mode is RGB565. So
Photon/io-graphics thinks the driver is trying to ‘set a bad display mode’
I believe this has been fixed for an upcoming release. Should you require a
fix
for a current product you should contact your sale rep.

Thank you for clarification.
The devg-pxa250 driver works fine in the “DE mode”.
Is the “fixed timing mode” supported too?

Michael,
It is possible to release this fix also for the QNX Neutrino 6.2.1?
The devg-pxa250.so description says that driver supports 8 and 16 bit mode.
But as we see this is not true under QNX 6.2.1 OS. Can you comment this?
Regards,
Jacek
I believe this has been fixed for an upcoming release. Should you require
a
fix
for a current product you should contact your sale rep.
As mentioned this is a known problem, but not in devg-pxa250.so. As
mentioned previously the 16-bit format for devg-pxa250.so is RGB556 which is
not being recognized by the
higher levels in the GUI system.
This fix could be done for 6.2.1, but I am not in a position to do that.
You will
need to contact your sales representative for options on acquiring a fix.
