Add OTA on ESP32

[Zapsalis]

Hi,

I am currently using an evalkit Nina W106-00B board that incorporates an ESP32.

I am desperately trying to implement OTA (Over-The-Air) updates.

I started by modifying my partitions.csv file, which looks like this (without OTA) and works well:

nvs, data, nvs, 0x9000, 0x6000,
phy_init, data, phy, 0xf000, 0x1000,
factory, app, factory, 0x10000, 1M,
storage, data, spiffs, , 0xF0000,

The "factory" partition corresponds to my .bin file containing the code.
The "storage" partition corresponds to my .bin file containing the web pages and .js files.

I tried to modify it so that when I add a new .bin file containing the code, it goes into the "ota_0" partition, for example, and then boots without using the "factory" partition.

This is what it looks like now:

nvs, data, nvs, 0x9000, 0x6000,
otadata, data, ota, 0xf000, 0x2000,
phy_init, data, phy, 0x11000, 0x1000,
factory, app, factory, 0x20000, 1M,
storage, data, spiffs, 0x120000, 0xF0000,
ota_0, app, ota_0, 0x210000, 1M,
ota_1, app, ota_1, 0x310000, 1M,

I can compile and flash it, but when I start my board, an error message appears in the logs:

ELF file SHA256: 73241a5f6639ca7a

This message keeps looping, and the board attempts to restart without success.

How should I modify my partitions.csv file for it to work correctly?

Thanks,
