Beginners • Re: thought experiment: privacy and security when working with sensitive data

Does that completely nuke or replace all EEPROM content or, as with uploading a '.uf2' file to a Pico, only update parts of it ? Re-flashing MicroPython for example leaves the complete file system intact, needs nuking to remove any secrets that may contain.

at least for the pi4, the .bin file covers the entire eeprom
but the recovery.bin will compare each erase-block between the .bin and the eeprom, and only erase/program when differences are found

i would assume the pi5 works the same

and on the pi4, it prints progress to the serial (gpio 14/15 on the pi4), including which blocks differed
pi5 may do the same on its debug header (between the 2 hdmi ports)
