Hi,

same issue here. we are using RGB666 and 16 bpp. The red color & blue colors are swapped but the image is clear. The pads are configured as per the hardware design based on reference manual.

we tried to swap Red & Blue in mxcfb_pfmt in mxc_ipuv3_fb.c 

  {IPU_PIX_FMT_RGB565, 16, {0, 5, 0}, { 5, 6, 0}, { 11, 5, 0}, { 0, 0, 0} }  . But the display goes blank.

Appreciate your help.
