I am working on a system where the half of the external flash memory was not assigned to a partition. That shall be changed now. But there are already some devices in the field, so I cannot just simply change the partition table via OTA update. At least that ist my understanding. Maybe that is wrong, and the partition table can be updated via OTA?
I was able to register a partition on the external flash via esp_partition_register_external(). I can read and write from that partition. The system runs the official micropython and calls the required IDF functions from micropython via user code.
But I have a problem when copying a new firmware image from that partition. I can successfully copy it to the OTA partition, but as soon as I call esp_ota_set_boot_partition(), the device hangs for the configured duration of the INT WDT and then reboots. So something is blocking the device from setting the boot partition and also from feeding the INT WDT.
Funny thing is: if the partition is not added at runtime but in the partition table, the WDT does not trigger a reboot.
I already have read the following issues:
https://github.com/thingsboard/thingsbo ... issues/158
-> here the problem was a dead lock in user code. The user code for OTA is almost directly used from an IDF example and does not involve mutexes.
viewtopic.php?t=5842
-> here the problem was insufficient stack for the underlying FreeRTOS. I have checked that the heap just before calling esp_partition_register_external:
