AM5728: Gamma table in Display Subsystem

Shine

Part Number: AM5728

Hello Champs,

System: FGPA->AM5728 PCIe->DMA->DSS->HDMI->ADV7511

Problem: the image outputting from AM5728 is red and not clear.

Customer was not sure if he had disabled the gamma module successfully, so he wanted to get the gamma table (256x8bit) to simuate it on Matlab.

Do we provide the gamma table?

Thanks.

Hi,

Gamma can't make the picture not "clear", and it'll only make the output red if the customer has modified the gamma table.
