@xykon For me it is sufficient as it is now.

@Xykon As mentioned by the esp-idf docs: The OTA data partition is two flash sectors (0x2000 bytes) Can you clarify why this is not the case for your otadata-partition? Edit: Never Mind-> https://forum.pycom.io/topic/3161/solved-invalid-partition-table-of-otadata-size-can-corrupt-ota_0-partition/2 you are not using the esp-idf related functions to perform ota.

Nice, I'll test this. Any idea if it's possible and how to have an option to flash build firmware done following this doc? Could really help because I'm building on a remote VM and don't have flash option
