HomeKit: Failed to write accessory ID to flash

[01matrix01]

Hello Maxim, I'm testing this board: ESP32-CAM https://loboris.eu/ESP32/ESP32-CAM%20Product%20Specification.pdf

I edit esp-idf/components/partition_table/partitions_singleapp.csv with factory, app, factory, , 2M, from 0x1F0000

I'm getting this error:

Thanks for your reply

You need to move base address for HomeKit settings storage since your change now makes it overlap with code app partition. In menuconfig (make menuconfig), go to Component config -> HomeKit -> SPI flash address for storing HomeKit data and change it from 0x200000 to 0x201000 (or 0x202000). That should be enough to unblock it.
