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; ----> 0
var->red.msb_right = 0;
var->green.length = 6;
var->green.offset = 5;
var->green.msb_right = 0;
var->blue.length = 5;
var->blue.offset = 0; ---->11
var->blue.msb_right = 0;
......
break;
case 24:
......
And then, I modified _ipu_ch_params_set_packing in
drivers/mxc/ipu3/ipu_param_mem.h, and found the color of UI is correct, but
camera preview/taking photo/recording, video playing are not correct (R and
B color are reversed).
I think the best way is to modify framebuffer, but I don’t know how to do.
Does anyone have some ideas?
BR,
Qingwei
