RP2350 does not respond to flash_nuke.uf2 #544

Closed TRadigk closed 2 months ago

TRadigk commented 2 months ago

Experiment: Copy over the flash_nuke.uf2 to RP2350 based PICO 2 board Observation: nothing happens. Expected behaviour: Controller is rebooted and flash is empty. Actual behaviour: Nothing happens, the file explorer remains open, until any other uf2 is copied which contains executable code.

Seems to work okay for me. Are you sure that you're using the latest https://datasheets.raspberrypi.com/soft/flash_nuke.uf2 (which is now a "universal binary") and not the older version (which was RP2040-only) ? Old version had a size of 25600 bytes, new version has a size of 98304 bytes.

If you built it for RP2040 it would behave exactly as descrived

You are right, this page is not updated: https://www.elektronik-kompendium.de/sites/raspberry-pi/2611111.htm (second google result and first where I learned that this file exists in the first place)

You'll be pleased to hear that https://www.raspberrypi.com/documentation/microcontrollers/pico-series.html definitely is kept up to date! :joy:
