Troubles getting Pro Micro to run

[JuLi0n21]

Hello TinyGo team,

Im currently struggling getting this Pro Micro to run. (datasheet)

I managed to flash to the mcu using the arduino-leonardo configuration but it seems to be doing nothing at all.

i started with a blinky script migrated from code written in arduino IDE, which also detects the board as arduino-leonardo.

i saw and experienced the same issue described in this issue

tinygo code:

package main

import (
	"machine"
	"time"
)

func main() {
	rxLed := machine.Pin(17)
	txLed := machine.Pin(30)

	rxLed.Configure(machine.PinConfig{Mode: machine.PinOutput})
	txLed.Configure(machine.PinConfig{Mode: machine.PinOutput})

	for {
		rxLed.High()
		txLed.Low()
		time.Sleep(300 * time.Millisecond)

		rxLed.Low()
		txLed.High()
		time.Sleep(300 * time.Millisecond)
	}
}

original arduino code:

int RXLED = 17; 
int TXLED = 30; 

void setup() {
  
  pinMode(RXLED, OUTPUT);
  pinMode(TXLED, OUTPUT);
}

void loop() {
  digitalWrite(RXLED, HIGH);
  digitalWrite(TXLED, LOW);
  delay(300);
  digitalWrite(RXLED, LOW);
  digitalWrite(TXLED, HIGH);
  delay(300);
}

flash command:
tinygo flash -target arduino-leonardo -no-debug main.go

i would be willing to create the missing pieces but i honestly dont even know where to start

@jespino
How was this part when you were developing it? It seems that writing to the atmega32u4 on an arduino-leonardo removes the USBCDC, making recovery difficult.

I also found this where some more differences are noted, cant confirm its the actual same board since their seems to be many different version of the board
