Oh, interesting. Uboot checks for file, if present load failover, else write file, load kernel, OS deletes file on boot. That works! My board is the Orange Pi Zero. I will try to implement this, thanks.

The problem is I believe those errors are given by the kernel, so u-boot has already passed things off to the kernel by that point. Maybe I'm misunderstanding. I will read the scripts again, thanks.

I customized my Armbian install with 2 operating systems on two partitions. In armbianEnv.txt I use rootdev to specify the default partition. I would like to set it so that if booting from the default rootdev fails (triggering panic or root-wait, etc.), it will instead try to boot with rootdev/root set to the other partition. Is that possible?
