hello friends
I have a begale board black and I want to run ubuntu or ubuntu core on it ,but after installing and turning on the first, second, and third lights, they turn off, But it does not give an image
i download the image file from https://rcn-ee.net/rootfs/ (https://rcn-ee.net/rootfs/ubuntu-armhf-20.04-console-v5.10-ti/2025-07-17/am335x-ubuntu-20.04.x-console-v5.10-armhf-2025-07-17-4gb.img.xz) and I use micro RAM sandisk 64g
I tested with these (https://rcn-ee.net/rootfs/bb.org/testing/2023-03-10/buster-lxqt-armhf/bone-debian-10.13-lxqt-armhf-2023-03-10-4gb.img.xz, https://rcn-ee.net/rootfs/bb.org/testing/2023-03-10/bullseye-xfce-armhf/am335x-debian-11.6-xfce-armhf-2023-03-10-4gb.img.xz) images, it works fine, but it doesn’t run ubuntu
have you zero’d out u-boot in the emmc ?
You need to watch the linux debug port using ttl adapter, until you can see the actual boot sequence you are not going far.
