Wisecoco 3.81" AMOLED Display Issue on Khadas Edge2 with Android 12

[therealdev]

Dear Team,

I am currently working with the Khadas Edge2 board running Android 12, built using the Khadas documentation available here: Edge2 Download Android Source Code [Khadas Docs]

I have tested two displays with the setup:

1. Khadas TS050 Touch Screen
2. Wisecoco 3.81" AMOLED Display: https://pt.aliexpress.com/i/33013441688.html?gatewayAdapt=glo2bra

While the TS050 works seamlessly, I am encountering an issue with the Wisecoco display when connected via HDMI. It consistently displays a distorted pink color. I have attached an image for reference to illustrate the issue.

I suspect the problem might be related to a missing Linux driver or an Android configuration that needs adjustment. I would greatly appreciate your guidance in resolving this matter.

Thank you for your time and support.

Hi @xiong.zhang

Thank you for your response!

I tested the setup yesterday with Android 14 (built from Khadas source code), but unfortunately, the system does not boot properly. It enters a continuous reboot loop. In the link below are the traces I captured via debug UART for your reference: khadas-edge2-android14-wisecoco-amoled-display.log - Google Drive

Looking forward to your insights on this issue.
