Serial logs are visible in display

[Hrithik]

Hi NXP Team,

We are using iMX8MM on Android 11 OS and it uses LVDS bridge based on i2c for display.
While the device boots up, the serial logs(UART logs) get displayed on the display screen.

Attaching picture for reference:

This is an undesired behaviour and we want to remove this.

Kindly guide us in removing the same.

Thanks

Hi @Sanket_Parekh ,

Thanks for the response.
Actually, we figured out that the logs were coming from Kernel as we hadnt defined console and stdout-path in kernel dts files as done in uboot.

Configuring the same in kernel solved the issue.

Hi @Hrithik ,

I hope you are doing well.

Please make sure that you defined the console in defargs environment variable in uboot.

Please provide me with the output of printenv in u-boot if this doesn't resolve the issue.

Thanks & Regards,
