Buildroot: Apalis iMX6 Remove boot messages from display

I’ve developed a custom image with buildroot. Now I want to remove the boot messages from the display not from the console. I’ve already able to autostart the application but I can’t figure out how to remove the startup messages from the hdmi display.

Anyone can help me?

Dear @matteo_s ,

Greetings and Thank you for contacting Toradex Community!

Firstly, you could try setenv bootargs quiet in u-boot. For further information please refer the information in: https://www.kernel.org/doc/html/v4.14/admin-guide/kernel-parameters.html

Or, Please kindly refer to the following developer article that gives an insight into how to silence the U-boot and kernel messages:

Alternatively, you could also a use a splash screen to display your custom image, while Linux is booting:
