I'm developing the product in this way:a HDMI source to ADV7619,and then output the RGB video data to FPGA. it has been working properly,but today,we test a new source,the output color is not  correct, likely all the colors are covered with a layer of purple.

Then i get the information from the register of ADV7619,found that the source is YUV709.No matter how do i change the register INP_COLOR_SPACE and RGB_OUT(RGB or YPbPr color space output),the display color is not changed. So i doubt if the CSC doesn't work and it is always BYPASS .
