hi, I meet a problem, directfb 1.2.6 can not work on my dm6446 board. the display is not regular. when i do df_dok .etc, the screen is blue.
i found the pitch is not correctly. i write a demo code in attachment.
i get the layer, then get surfacem then lock it and get pitch.
for video layer it should be 2176.
i also add a info info gfxdrivers/davinci (print line_length), and it
show pitch show be 2176. but i found 1440 used in directfb.
any patches?
thanks.
NEW:
today, I tried Lock the surface, then directly copy uyvy data to
buffer using pitch 2176, the display is ok.
PS: I use TI'LSP 1.10 patch level 50.
