Hello, I'm new to Raspberry, so please forgive me if I say stupid things :) I bought an Axzez Interceptor Board, and I've received from one of my friends a Raspberry CM4 with eMMC storage. On the Pi CM4 has been installed the following OS by my friend before to give it to me: =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- PRETTY_NAME="Debian GNU/Linux 11 (bullseye)" NAME="Debian GNU/Linux" VERSION_ID="11" VERSION="11 (bullseye)" VERSION_CODENAME=bullseye ID=debian HOME_URL="https://www.debian.org/" SUPPORT_URL="https://www.debian.org/support" BUG_REPORT_URL="https://bugs.debian.org/" =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- I've tried to boot from USB, but with no success. Always boots from eMMC storage. I've tried via rpi-config command to change the boot order, I've downloaded the OS from you, and made a bootable USB with Raspberry Pi Imager (on Windows machine), still not booting from USB. Is there a way to install/reinstall/reflash the eMMC with another OS? If yes, could someone help me with that and provide me with some hints?
