Hi everyone,
I`m working on DM8148 boot logo on DVO2 with 720P60 ..
Now the dvo2 port of hdvpss is set to 720P60 and work well (tv can detecte 720p60 signal correctly).
But there is no logo data on tv. Just something like background data(black screen) is show on tv.
I have no idea to debug on tihis problem. Something wrong with grpx / vpdma setting ? Can you give me some advise to debug ? Thanks verymuch.
My logo data is loaded by tftp at uboot stage : "tftp 0x82000000 car.bmp; "
start logo display at uboot stage : " logo on 0x82000000 0xA0000000 0x81600000 10 60 "
(logo on img_src img_dst vpdma_desc_dest disp_time disp_fps)
here is the code .
