# After the installation, you need to upgrade your U-Boot to the latest mainline,
# which can be extracted from Armbian package linux-u-boot-espressobin-edge.
# Once you flash the U-Boot, you need to backup your mac address,
# and then run `env default -f -a` to clear preexisting congfiguration.
# If you do not backup your mac address you will get a random new one on every boot.
# See Final steps in https://marcin.juszkiewicz.com.pl/2021/02/15/ebbr-on-espressobin/
# Then you will need to add an entry to boot grubaa64.efi as a workaround,
# since the default bootaa64.efi cannot boot the device.
# Something like (check your existing bootcmd first with `env print bootcmd):
# env set grub_bootcmd "load mmc 0:1 ${fdt_addr_r} /dtb/marvell/armada-3720-espressobin.dtb;load mmc 0:1 ${kernel_addr_r} /efi/boot/grubaa64.efi;bootefi ${kernel_addr_r} ${fdt_addr_r};"
# env set bootcmd "un grub_bootcmd;run distro_bootcmd"
# env save
# For more info on U-Boot please visit: https://www.armbian.com/espressobin/
# In some cases your U-Boot will enter a reset loop, with the final output like this:
# BootOrder not defined
# EFI boot manager: Cannot load any image
# 856064 bytes read in 44 ms (18.6 MiB/s)
# Booting /efi\boot\bootaa64.efi
# Reset System
# resetting ...
# In this case you have to boot your board manually:
# load mmc 0:1 ${kernel_addr_r} /EFI/BOOT/grubaa64.efi
# bootefi ${kernel_addr_r}
