Hi,
Now I have to use BGR565 instead of RGB565, so I modified following codes,
but they have no effect.
file:
mxc_ipuv3_fb.c, function: mxcfb_check_var
..
switch
(var->bits_per_pixel) {
case 8:
..
break;
case 16:
var->red.length = 5;
var->red.offset = 11;
Hi Qingwei,
The correct way is to modify in your frame buffer display driver , just swap
between B and R
The frame buffer display driver is in your linux kernel driver
/linux-xxx/drivers/video

Tung

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.
anges, or driver has bugs.
