VGA red and blue swapped on iMX6 dual plus

[matbus]

We have built a board with an iMX6 dual plus where the analog display output has been swapped so that the red component is output to DISP0_DAT0 through DISP0_DAT7 pads. Is there a way to re-configure this in software?

Ok, thank you for the answer. So the hardware should be updated to get blue bits from DISP0_DAT0 through DISP0_DAT7 pads?

(We have a hardware revision in progress and want to make sure we are not doing a hardware change because of a software misconfiguration).

@igorpadykov can you confirm that the correct color order is blue, green, red counting from DISP0_DAT0? Thanks,Mattias

Hi matbus

I am afraid there is no simple way to make remapping as it is fixed in driver and

described in 4.12.10.4 IPU Display Interface Signal Mapping

i.MX 6DualPlus/6QuadPlus Applications Processor for Consumer Products Data Sheet

in general bus mapping is described in sect.37.4.7.5.1 Bus Mapping Unit
