L01, Lopy4 losing firmware
I have struggled with this before. I have a number of Lopy4 boards in the field. Some of them lose their firmware while deployed. They would stop working and then when I troubleshoot them they have vanilla firmware and nothing else programmed. Lately, I have moved to L01 devices and I now have the same problem again.
The devices are using LittleFS. I urgently need assistance to keep these units from losing their firmware, or at least some explanation why this is happening, so I can take preventative measures.
Secondly is there a way to load a bin file, like the vanilla bin file, which would replace the file system if someting goes wrong.
Thanks for the help!
