Running photon 16-bit mode on daytona board.

I’m using QNX 6.2.0 on Intel daytona (XScale) board.
On this system, io-graphics is exeucted with 8bit color mode like below as
default.

io-graphics -dldevg-pxa250.so -g640x350x8 -a mode=/proc/boot/pxa250.conf

As far as I know, daytona board supports 16bit mode. So I just changed above
parameters to like below.

io-graphics -dldevg-pxa250.so -g640x350x16 -a mode=/proc/boot/pxa250.conf

But screen doesn’t appear, just black screen.
What should I do for running Photon with 16bit mode on Intel’s Daytona Board
?

I don’t believe we ever got the Daytona to work at 16 bits per
pixel. The developer of the graphics driver is currently on vaction.
He’s back next week; hopefully he’ll be able to provide a more
detailed answer.

16-bit mode is possible on the Daytona with devg-pxa250.so

Can you post the output of ‘uname -a’ ?

Can you run slogger in your image and post the output of ‘sloginfo’
after you get the black screen?

Thanks
