Dear Carl,
Our application is same as yours, but a little different.
LCD 800 X 480
TVE TV-NTSC
I followed the user guide to modify the init.rc and complie and replace the files: overlay.imx5x.so, gralloc.imx5x.so.
The result is LCD display not normal, TVE is green.
Uboot cmd:
console=ttymxc0,115200 init=/init quiet lpj=4997120 pmem=32M,64M fbmem=10M gpu_memory=96M vmalloc=512M video=mxcdi1fb:YUV444,TV-NTSC tve androidboot.console=ttymxc0 di0_primary video=mxcdi0fb:RGB24,CLAA-WVGA
