Our customer wants to perform any time a rollback to the previous Image. Even though a new update was successful and committed, he wants to have the possibility to roll back to the last version later on.
Our approach:
Before an OTA update starts, create a copy of the actual mculfashimg.bin (read mculfashimg.bin -> write in mcuflsasimgcopy.bin) . Then perform a regular update.
If at some time a custom rollback is necessary, the copy of the mcu binary will be read back to the mcuflashimg.bin (read mculfashimgcopy.bin -> write in mcuflsasimg.bin)
Both file are created with failsafe mode. This means, a bigger SFLASH has to be considered. But do you think, that this approach is feasible?
Thanks for your support.
