DNF out-of-memory failure
DNF is quite memory hungry in its current state leading to OOM errors on systems with only 256MB RAM some of which is allocated for GPU.
As it gets worse with large repositories we're considering splitting our repository into smaller chunks (e.g. minimal, desktop, ...).
Workaround around this issue is to enable swap either on your partition if you have it or create a temporary swap file on local file system.
# create 256MB swap file at /swap dd if=/dev/zero of=/swap bs=1M count=256 chmod 600 /swap mkswap /swap # enable it swapon /swap # proceed with dnf update, you can delete /swap when # you no longer need it, make sure to issue 'swapoff' before

Verify your device has time synced with network:
date timedatectl chronyc tracking chronyc sources
If network is available chronyd should find sources and sync time of your device. If this is not the case try restarting chronyd with
systemctl restart chronyd
U-Boot needs setting ethaddr and usbethaddr to some MAC address. This MAC address will be only used for booting and changed to pre-flashed MAC afterwards. You can break to U-Boot by pressing SPACE after Raspberry Pi startup - you need USB to UART converter attached for this.
setenv ethaddr B8:27:EB:13:37:2B setenv usbethaddr B8:27:EB:13:37:2B setenv bootcmd run bootcmd_pxe saveenv reset
To reset U-Boot environment to default state use
env default -a
