Hi
When Beaglebone black boots, the following error message is displayed.

I don’t use any LCD with Beaglebone black.
So Beaglebone black doesnot need HDMI

Is there a way to prevent those messages from appearing in the config configuration before compiling the kernel?
If not, is it possible to configure after running linux on Beaglebone?

Please, let me know how to do them.

Regards

Hi @taek8461, since your board is not a real BeagleBone Black, you should stop booting the BeagleBone Black Device tree.

Take a look at the BeagleBone Green’s Device tree, it’s very similar to the Black, just no tda998x HDMI encoder.

Hi
Could you explain it in more detail?
I am not good at Device tree.

With your custom board, today you are booting the BeagleBone Black, (which has the HDMI encoder)

am335x-boneblack.dtb

Instead boot with the BeagleBone Green:

am335x-bonegreen.dtb

As it’s identical to the BeagleBone Black except no HDMI encoder.
