Re: booting Beaglebone Black

["Dr. Nicola Mingotti" <nmingotti%gmail.com@localhost>]

Hi,

I had difficulties with be BB Black a few months ago.

Please look in this mailing list at my post of 25-Apr-2024,
subject: "Can't boot 10 images on BeagleBone Black".

Follow that thread, you will be able to boot, I was.

bye

Nicola
