Burned ubuntu-19.10-preinstalled-server-arm64+raspi3.img.xz. First boot on RaspberryPi 4 looked ok until it hung after

[ OK ] Reached target Cloud-init target. 

Power cycled, and boot ended with

Ubuntu 19.10 ubuntu tty
Ubuntu login: [  23.431015] cloud-init…
[...] cloud-init…

Then no response to keyboard input, in USB2 or 3 port. The same procedure worked fine (successful login, etc) on first boot with a RaspberryPi 3.


Set total_mem=3072 in /boot/firmware/usercfg.txt (If you mount the sd card in another computer, the usercfg.txt is on the small vfat partition.)

  • It’s /volumes/system-boot/usercfg.txt, not /boot/firmware/usercfg.txt, on my mac. Added total_mem=3072 and it works. (This is a new setting, not overriding one in config.txt.) Many thanks! – Chris Haynes Nov 3 '19 at 16:36
