We are working on our carrier board, which implements an 800x400 TFT display, recently installed Linux V2.8 on these modules.
When turning on the display for the first time it only showed black lines on a white background, so I decided to change the display configuration through the command prompt with the following line:
setenv vidargs ‘mxc_lcd.only_cea=1 video=mxcfb0:dev=lcd,800x480@60,if=RGB666
video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off fbmem=32M’
with this modification I can see the image but it comes out in pink tone, I attach an image.
I think this is caused by the configuration of LDDS, this error also happened in WEC7 and it was solved by setting LDDS = 24.
I was searching and I can not find how to change this value on Linux.
Can it be done from the console?
