How to flash a new u-boot on Turris Omnia

[anon50890781]

Different topic though

@cynerd

Firmware is stored on nor memory on board and can be updated voluntarily with nor-update but even that only updates it to version we consider stable

@cynerd

It can also update it to development version (latest build shipped with system) but that version is not tested and advice is to not use it.

@miska

Once you boot your Omnia (you can use omnia-initramfs-zimage from the link bellow), erase partitions mtd0 and mtd1 and write into them files from https://repo.turris.cz/omnia/nor_fw/

uboot-turris-omnia-spl.kwb to /dev/mtd0
omnia-initramfs-zimage to /dev/mtd1
