Hello,

 

Recently been putting together the Pi which has been a lot of fun (starting to get a lot better at soldering). Wired everything up to the MicroSD card, and when it turns on it turns off after about 3 seconds of loading the OS. Has anyone else had this problem?

 

Heres a video.

Is that using a Zero W?

Ah also investigating found a part that came dislodged on the ON/OFF board. Looks like it might be a problem. Do you know when you should have them in stock again?

Ok I was asking about the Zero W because it doesn't automatically pull up the TX pin. A line of code has to be added to config.txt to make it function properly.

That damage could definitely be your problem though. I'll have everything back in stock on Sunday. Also, that's just a 100k ohm resistor. If you have a regular 100k laying around you can solder in it's place that should get you up and running.

Yeh resoldered the resistor + added the config boots like a charm. Only problem is the switch won't turn it back off for some reason! Haha

Does holding the switch for a few seconds kill power to everything (it should)?

If that works then you just need a bit of software to run in the background to look for a GPIO pin to go low.  You can use the GPIO Shutdown from v3 to accomplish that.

You'll need to modify it to for whatever GPIO you chose for shutdown though.
