Software reset to bootloader mode - code example

[madias123]

Maybe worth as an example:
A simple code, triggering the Pi Pico into bootloader upload mode. (You'll need this for zero-knowledge customers, so they can update the firmware simply with drag&drop when the select "update firmware"):

extern "C" {
#include "pico.h"
#include "pico/time.h"
#include "pico/bootrom.h"
}

Then force upload mode with just one line:
reset_usb_boot(1<<PICO_DEFAULT_LED_PIN,0); //invokes reset into bootloader mode

Why not add it to rp2040 as rp2040.rebootToBootloader() ?

I.e. extend:

arduino-pico/cores/rp2040/RP2040Support.h

Line 309 in 3f475ac

void reboot() {
