Usage of mender - updating back to u-boot

Usage of mender - updating back to u-boot

[Patrick Schneider]

Hi everyone,

for a customer (who wants to use mender) we need to switch from barebox to u-boot. Is it somehow possible to flash a u-boot image using a running barebox?

Or even better, does somebody know if mender is supported in barebox?

Thanks and best regards,
Patrick

In general, yes, you can write a U-Boot (or any) binary image to
appropriate non-volatile memory device using "memcpy"(or plain "cp" if
no special offset handling is needed). However the devil is really in
the details and depending on the HW you are running on some particular
use-cases/scenarios are not supported.

No, I don't think mender is supported. Closest thing to mender that is
supported would be RAUC: https://rauc.io/
