Ah there we go, Debian 10.x (Buster) built on 2019-09-01… (root password should be root)
Just grab the Debian 11.x (Bullseye) image from here: Debian 11.x (Bullseye) - Monthly Snapshot - 2023-10-07
Minimal or IoT… unless you really want a slow desktop…
Personally I’d go with this one: https://rcn-ee.com/rootfs/release/2023-10-07/bullseye-iot-armhf/am335x-eMMC-flasher-debian-11.8-iot-armhf-2023-10-07-4gb.img.xz
Use etcher.io to flash it to a microSD
