1. My understanding from the documentation is that neither OTA or OTA2 will work with only internal flash, is that correct? The MCU has a 1MB internal flash for reference.

2. for the internal flash layout , need your help to check the directory :
the file has the detailed addresses for the bootloader and app arrangement
