BOOTSEL via Reset button

[fapplin]

I have added a button that is connected to GND and RUN. It resets just fine. I would like to be able to add the bootsel capability via hitting the reset button twice. The SDK has the following info.

pico_bootsel_via_double_reset - When the 'pico_bootsel_via_double_reset' library is linked, a function is injected before main() which will detect when the system has been reset twice in quick succession, and enter the USB ROM bootloader (BOOTSEL mode) when this happens. This allows a double tap of a reset button on a development board to be used to enter the ROM bootloader, provided this library is always linked.

Is this capability in this core? Is there anything I need to do code-wise?

Thanks,

Frank

Can you try #893? Add rp2040.enableDoubleResetBootloader() to your setup and it should link in the SDK code to check for a double reset tap.

Do a git pull and try again. I've just hacked together an old PC reset switch and some hookup wire and tested it to verify it's working on my own system now.

My LittleFS upload seems to have gone away in the 2.0 IDE tools menu. So, I'm getting an error No drive to deploy. Do I need to go back to the old IDE?

OK. Got it working in the 1.8.19 IDE!!!!! Reset and BOOTSEL on double tap!!!

Yup, there is no plugin support at all for IDE 2.0. See arduino/arduino-ide#58

That sucks. The 2.0 IDE is almost a real IDE finally! Thank you again for your help!
