PROCESSOR-SDK-AM62X: AM62x DPI 24-Bit RGB LCD Timing Issues

Part Number: PROCESSOR-SDK-AM62X

Tool/software:

Hi, TI:

     We use the AM62x platform's DPI interface to connect to a 24-Bit RGB LCD. The LCD requires that the pixel data be sampled on the falling edge of the clock. However, actual testing found that the data sent by the LCD is valid on the rising edge of the clock. What is the reason for this? As shown below:

    We modified the panel-simple.c file and adjusted the value of the IPC bit in the 0x3020b04c register, but it had no effect.

   It is quite urgent, please help as soon as possible. How to modify it so that the pixel data is sampled on the falling edge of the clock?
