Android Boot Logo on MIPI-DSI failed to change

Which Khadas SBC do you use?


Which system do you use? Android, Ubuntu, OOWOW or others?

Android 9 Pie

Which version of system do you use? Khadas official images, self built images, or others?

Khadas official images (vim3-android-9-64bit-v230408.img) & self built images

Please describe your issue below:

Android boot logo failed to change on the MIPI-DSI LCD.
But it changed on an HDMI display successfully.
Do they operate separately like that?

I followed instructions from the link below.

I tried 2 methods all with the same results.

  1. “Burn the logo.img Separately” with the official vim3-android-9-64bit-v230408.img.
  2. “Update the logo by upgrading whole firmware” with a self-built update.img.

Post a console log of your issue below:

This is the log on U-boot mode.

Hello, is the MIPI-DSI you are using TS050? If yes, then you need to replace the




in the


directory with the logo picture you made. It is best to modify it to the picture you need according to our original one. Note There are two that need to be rotated

Yes it’s TS050.
Now, boot logos are changed successfully on both displays.
