Android-13 : MIPI-DSI display not working

kishan_dudhatra — Tue, 24 Oct 2023 07:45:59 GMT

Hello,

I am working on an i.MX 8MM-based custom board. The MIPI DSI display was working in Yocto Kirkstone (5.15.71 kernel), but it is not working in Android 13 with the same kernel version and the same display controller driver ported from Kirkstone. There are no error logs related to the display or DRM. The display bridge is attached successfully and I am able to see the display through the visor utility, but I am not able to show anything on the MIPI-DSI display. In addition, the driver is probed and the display init command is sent successfully. Adding the display init commands did not help to show anything on the display.

Note: We are able to shows the display in u boot successfully.

Android Version : 13

Display controller: st7701

Please let me know if any further information is needed.

Hi,
Thank you for your response.
I made changes according to your suggestions and followed the Android User Guide, but it didn't help to fix the display issue.
