DRA718: How to change different LCD in DRA Android

Part Number: DRA718
Other Parts Discussed in Thread: DRA71XEVM

Dear Sirs:

  We are trying to move from DRA71xEVM to our custom board for the android.

  We use PROCESSOR-SDK-ANDROID-AUTOMOTIVE  6AO_1_1_Release.

  On J6 Entry (DRA71x) EVM, we are able to change the LCD from AUO panel to LG panel which is used on J6 EVM board. The both LCDs have the same resolution 1280x800.

  However in our custom board, we use a 1024x600 LCD.

  We modify the device tree to add our panel and setting the timing. But eventually the android did not show anything on the panel. And the LCD device tree part is verified working in Linux PSDK.

  Can you give me any hints to know what could I possible missed during changing the LCD?

Regards,
