Hello, how to modify the default address of the partition table 0x8000

[stick88]

I really want to know how to modify the default address of the partition table at 0x8000. I want to modify it to 0x10000. If I simply write the partition table to the address at 0x10000, (of course I modified the location where the bootloader reads the partition table), it will appear The arduino loop program will not find the partition table, " initArduino(): Failed to initialize NVS! Error: 261"
thank you very much.

of course I modified the location where the bootloader reads the partition table

what did you modify?

[stick88]

Use idf to modify the bootloader to read the partition table at 0x10000

The question i have, why do you want to do this?

[stick88]

Because I added secure boot and flash encryption the bootloader got bigger。

[stick88]

I reduced the size of the bootloader to less than 32KB as much as possible, and the flash has been successfully read and written, but the new problem is that the new firmware cannot be activated using the webupdate sample program OTA

Have you tried to move the partition table behind the App sections (OTA 1 and 2)?
Afaik the first started firmware has to be at 0x10000 (OTA 1).
Maybe what you want to do is not possible with Arduino. There are some fixed values choosen you cant easily change. If you want to use encryption switch to IDF.

@stick88 I modified our (Tasmota) Platformio espressif32 framework to support a different address than 0x10000 for app0 (it is hardcoded in official version). All other bootloader, partition table and boot_app0.bin are still hardcoded https://github.com/espressif/arduino-esp32/blob/master/tools/platformio-build-esp32.py#L330-L333
Not tested if it is possible to change this too.
