Deay Guys:
These days, I encounter a struggle question which is in BBB bare metal
display!
Following are my condition and question:
1. I design a raster display for mobile LCM which work in 800x1200@60Hz.
(In bare metal)
--> I use TTL 24Bits (RGB) + Hsync + Vsync + PCLK + DE for display
timing.
--> I write several pattern on the LCM and it works normally.
2. Today, I got a 1080x1920 LCM and just want to light on it. But the
screen is abnormal.
But I reduce the resolution to 960x1920 and display is success!
3. Is that the DMA size mis-match? If is so...How to modify it? Some body
could guide to me?
or
BBB NOT support resolution which exceed 960x1920?
Have a nice day~
