Just a clarification about error from my previous post from BUP update (Specifying the size rootfs of a partition (-S) breaks DT upgrade - #12 by mr.ivanov).
strace I found out that problem is not related to the rootfs location. It’s just missing
openat(AT_FDCWD, "/etc/nv_boot_control.conf", O_RDONLY) = -1 ENOENT (No such file or directory)
However I still want to share this info for another board users or engineers, because origin
nv_update_engine error is bit confusing and looks like this:
$ nv_update_engine -i Nvidia A/B-Redundancy Update tool Version 2.0 null input file! Init SMD partition failed! null input file! Init SMD partition failed! null input file! A/B has been disabled. Need to enable A/B. Error: installing bootloader updates failed: -22
I think it would be nice to have a more clear output from
Configuration file /etc/nv_boot_contol.conf not found instead of unobvious
null input file!.
However, problem is resolved and I can confirm that BUP update from SATA pass correctly
