Hello to everybody,
I have this evaluation board at91sam9263 from Atmel and few weeks/ month
the custom kernel is running on it.
Everything works fine (USB, Ethernet, Sound, etc).
I am also able to view pictures on the display and also I can draw
rectangles and text via directfb on the screen, but unfortunately I have
a problem to display the correct colors.
If I try to view a picture via the command fbv or df_databuffer the
colors red and blue are swapped, the same holds true for an video via
mplayer (with the option -vo fbdev2 ).
But when I convert the same png file to a ppm and exchange it with the
tux boot logo, this will displayed correct in RGB colors. (But only
during this boot process is this logo visible and correct)
And also a strange thing is that when I write by myself (via a small
C-Program) values to the device (dev/fb0 ) I get the colors red, green
and blue but in a different order. Here is red, red (0xF800) but green
is blue (0x07E0) and blue is green (0x001F) and I am writing those hex
values directly to dev/fb0.
Also research through the internet was unsuccessful because not many
people facing the same problem. I have read some workarounds for RGB24
to BGR24 for a directfb patch, but in my case I use RGB16 and all the
attempts to change the RGB to BGR fails. Maybe also a problem is that I
am not able to change the settings from directfb everything will be
canceled and directfb falls back to its default RGB16 setting.
Sorry, that I am new to this topic, maybe someone can give me a hint or
a good advice.
Thanks a lot.
Best regards
Sven
