Flash error on M2 Mac about tinygo HOT 4 CLOSED

Quickly verified that there's no issue with the arduino itself by using the arduino IDE with a blink example:

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(1000);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW
  delay(1000);                      // wait for a second
}

works as expected

Tinygo error seems to come from here https://github.com/tinygo-org/tinygo/blob/dev/main.go#L972

flashUF2UsingMSD called with options here https://github.com/tinygo-org/tinygo/blob/dev/main.go#L484

issue seems to be the config.Target.FlashVolume that's part of the config built here https://github.com/tinygo-org/tinygo/blob/dev/main.go#L374

So we're calling the Flash function if the option is flash https://github.com/tinygo-org/tinygo/blob/dev/main.go#L1635

the config is built https://github.com/tinygo-org/tinygo/blob/release/builder/config.go#L14 because what in there is related to this https://github.com/tinygo-org/tinygo/blob/dev/main.go#L1514

target: https://github.com/tinygo-org/tinygo/blob/release/builder/config.go#L38

Okay, so we have the flash volume in there

Okay so we load from https://github.com/tinygo-org/tinygo/blob/release/targets/nano-rp2040.json

and then the inherits https://github.com/tinygo-org/tinygo/blob/release/targets/rp2040.json

okay, but where does the flashvolume come from? This is kinda where I'm getting lost

Via Slack:
you probably need to manually kick-in the bootloader the first time flashing that particular board

Hold down the BOOTSEL button while plugging the board into USB.
you only need to do that once. afterwards, tinygo will detect it is being flashed and kick into bootloader mode
usually if the rp2040 board has already been flashed with something like arduino, it will also work without manual bootloader

from tinygo.

local machine issue: fixed by reboot
