there are various boot modes which can be chosen by different GPIO voltage levels. Is there also a way to change the currently running user binary?
Let's assume I use OTA firmware updates. One day I accidentally upload a new version which has broken OTA support. Ooops. Now I cannot correct my mistake: The firmware has a correct checksum and it starts fine. So the bootloader will run it on every power on. What options do I have besides re-flashing the module?
It would be cool if there was a special GPIO setting to force either user1 or user2...
