TDA2E: Questions: About yuv422 display

Part Number: TDA2E
Other Parts Discussed in Thread: TDA2

Hi, Support

The processor we use is TDA2 ECO 23*23. My video output resolution is 1780*720, When I RGB output video, everything is normal. When I yuv output, a part of the picture is green in external display.I used dss to convert rgb to yuv, it was normal before conversion, and part of it was green after conversion.I use jtag dump dss link image,i use 7yuv to view the image. When the resolution is 1780*720, the image is distorted and some parts are green. When the resolution is 1784*720, the image is not distorted, but there are green parts.

  • Hi yongzheng lv,

    The first issue is due to pitch/line offset, it must be 16byte aligned. 1780x2 is not 16byte aligned. but 1784x2 is 16byte aligned.

    I think Green bar is due to input image. Are you sure sensor is outputting frame of size 720 lines? 

    Rgds,
