Hello Wayne Feng
I think the DCU offset is wrong. This was found previously by vincent.aubineau
But should be:
According to the reference manua rev 4
"The CLUT/Tile RAM is mapped in the DCU4 32K memory space from address 0x2000
to 0x3FFF. This gives 2048 entries, which provides up to eight full CLUTs for 8 bpp
Can we have this Change Request for the next release 0.6.0 of the drivers?
