Sorry for mistake: should be BGR565 instead of RGB565 From: lqw1...@gmail.com Sent: Thursday, September 08, 2011 8:06 PM To: android-porting Subject: i.MX51 BBG: How to swap red color with blue on DIPS2 (RGB565)
Hi, Now I have to use BRG564 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?
