How to verify what code is programmed into memory

[Dandy-Don]

I'm curious how to know what code is programmed into the RP2040 board.

I sort of understand that CRC can be used on Atmel & Microchip microcontrollers to verify what code has been programmed into the chip. Is there a way to do something like this using Micropython & RP2040 chips?

picotool verify verifies the uf2 file on your local disk against the contents of the RP2040.

The USB Flashing Format (UF2) is rather complicated compared to Atmel chip dumps, and may not be useful for direct binary comparison

Thanks, scruss!

I've never used picotool. I'll have a look & see how to use it....
