Firstly, I want to appreciate your work.

But now to my problem. When I have this code as main.py:

from machine import *
import picosleep

led = Pin(25, Pin.OUT)

def blink():
    led.toggle()

while True:
    picosleep.seconds(3)
    blink()

my Pico doesn't seem to be accessible when connecting it to the computer. So when I want to make changes to the program, I have to flash_nuke it in order to function.

Maybe this is my error, I'm just new to this subject :)
Anyways, any help would be appreciated!
