Booting Ubuntu 20.04 from USB on a Raspberry Pi 4 with new bootloader

I am trying to boot my RPI 4 from USB without using a SD card. I am able to boot Raspberry OS after updating to the latest firmware/bootloader but I'm not able to figure out what to do to get ubuntu to boot. Any help will be appreciated.


Solution 1:

I'm not sure if normal "plain" Ubuntu works on the RaspberryPi 4. I assume that you'll need a special arm version that's also optimized for the Pi. According to the official Raspberry Pi Downloads page, Ubuntu MATE, Ubuntu Core and Ubuntu Server are supported. You might want to try one of these images!
