Hi Tung,
I have tested my FB driver, it’s OK! And I found Boot logo can swap color, but
android system can’t.
I’m puzzled with this. Does system not use FB?
Best regards,
Qingwei

Hi,
Now I have to use BRG564 instead of RGB565, so I modified following codes, but
they have no effect.
file:

switch
(var-bits_per_pixel) {
case 8:

case 16:
var-red.length = 5;
var-red.offset =
Sorry for mistake: should be BGR565 instead of RGB565

Hi, Dang,
We’re using driver/video/mxc/mxc_ipuv3_fb.c as framebuffer driver, and I think
the only thing I should do is modify check_var to re-define fb_bitfield, right?
Or I should modify other file? Could you please give a example or further tips?
Thanks a lot!
BR,

Hi Tung,
Thank you!
I have ever done the similar thing with our FB driver, but it did not take
effect. Maybe our platform made some special changes, or driver has bugs. I’ll
check them carefully.
BTW, I wonder if there is another way to implement, e.g. modify fbmem.c or
other files.
Best
