Hi Roland,
my first thought is that your screen is BGR24 instead of RGB24.
I do not think it is an endianess problem, since RGB24 is generally
copied byte-by-byte.
BGR24 is currently not supported by DirectFB but in general a new pixel
format can be added within a day.
You also might try "dfbdump -ds -dl" to dump the current layer and
surface content to check if the DirectFB internals are correct (which is
what I expect if your screen is BGR24).
Greetings
Niels

Dear DirectFb experts,
I am working on a board with an AT91SAM9263 processor (an ARM
processor) basing on the ATMEL evaluation board AT92SAM9263-EK.
Accessing directly to the framebuffer works fine (we run RGB24 mode
per default), and the colors are shown correctly.
When we use DirectFb, the display shows a blue color instead of a red
one and vice versa.
When I set the bg color with pure red (dfbg –dfb:pixelformat=RGB24 –c
FF0000) I get a “blue screen” on the display.
This behavior I observed on all tested DirectFb versions: 1.0.0,
1.1.1, 1.2.5, 1.2.8, 1.3.0 and 1.4.0. Version 1.3.1 is not producible
because of a compiling error in memcopy.c
We run a 2.6.27 kernel
In attachment you will find all console logs.
If you need more details, please let me know.
Thanks in advance for your help,
Best regards
Roland Patauner
