Debugging different problems

- Pinecil doesn't power on at all

 - Check your PSU - it might be faulty
 - Check cable
 - Use different kind of PSU (if you're using a barrel jack one, try a Type-C one, and vice-versa)

- Pinecil shuts down when connected to a Type-C PSU and trying to request a higher voltage (needs a bit more clarification)

 - Update firmware - factory firmware has quite a few USB-PD problems, which the newer firmwares fix

- Pinecil randomly resets when touching solder

 - Using PinePower or some other grounded PSU?
   - This is likely to be a grounding problem.

- Doesn't power on after applying 24V

 - The FUSB302 might have gotten damaged and shorted an internal power rail (has verifiably happened before)
   - Fix is to use a hot air gun to remove the FUSB from the board. You can leave the iron without the FUSB302 IC, or you can find and buy a replacement.
   - Without the FUSB IC present, you will lose USB-PD compatibility - the Type-C jack will not power your Pinecil with a C-to-C cable, or from a PD-capable PSU with attached type-C cable (laptop PSUs)

- Pinecil tip heats up too much, starts to glow and [REDACTED]
