Python • Re: Rasp pi Pico wont work once soldered to headers

So, let's dissect this because your problem may not have anything to do with soldering

Setting up pico and went through the setup on thonny, got the onboard led to turn on etc. Soldered half the header pins on and it still worked. Finished the other side and now this error pops up when i try to install micropython.

My understanding:

• So it sounds like before soldering, you were able to get the uPython firmware to load correct?
• Soldered half the headers and still able to install uPython from Thonny
• Finished the other side then you got the error when you tried to load uPython again.

I'd suggest getting a magnifying glass and a good light to check that your solders do not touch some other surface.

As to the error, I have found problems with the USB port connecting the PICO to the computer to the point that I have to reboot both computers to get a clean new connection. You may want to try that.

can only print stuff.

What do you mean? Like from Thonny or print() statements in uPython?

Finished the other side and now this error pops up when i try to install micropython.

Is the uPython error displayed after you have attempted to load the firmware? Are you sure your Thonny interpreter is still pointing at the PICO?

Check your soldering but this could also be a USB connection issue.

Also look at MPREMOTE. It's the official uPython connection software to the PICO https://docs.micropython.org/en/latest/ ... emote.html
