Thanks Jonas! Yes, I tried Swupdate, but not RAUC. I will try out and check it deeply!
I would like to create my own solution (as a learning path too). In this case, if I think good, that possible to solve with systemd (emergency boot etc) and uboot. I thought I can solve that with a kernel module or something similar, with an init script. I saw one solution.. but I forget where.. that was really smart hobby project on github. Therefore I asked the community, maybe somebody have experience in this area.. which is the best way to start that.
