CM3 fan not on
#1
I already have a post open right now for the cm3 not wanting to fit with the pre-installed heat sink, but I have another issue and didn't want to post them in the same one in case one's an issue for someone else later.

I assume there's just a setting somewhere to turn it on or off, or maybe it's set to come on at a specific temp, I'm not sure. How would I go about getting it to work or verifying it's functioning correctly?

The solder is good and the wires don't get pinched when the shell is assembled.

I just saw the end of the install document where it lists what to run, my bad lol

I don't think there are any issues

Yes, hold please...

Okay.  Thank you for holding while I looked up the info.

At the bottom of this document, there is some detail about the fan.

https://docs.google.com/document/d/13ztk...2r9lbuyvvf

Basically, you just need the gpio-fan overlay.  Definitely look at that link (above), so you can know how to make sure that file exists.

You can do
ls /boot/overlays/gpio-fan.dtbo
or pop the SD into your computer and see if there's a gpio-fan.dtbo file in the overlays directory of the "boot" drive.

If you need it, get the file from https://github.com/raspberrypi/firmware/...o-fan.dtbo or read the document linked above for other options (like compiling it yourself on the Pi).

Once the file is there, add one line that looks like this near the bottom of /boot/config.txt, or edit a line that has dtoverlay=gpio-fan if it exists:
dtoverlay=gpio-fan,gpiopin=40,temp=60000

You could also use https://github.com/TheFlav/rpi-fan if you prefer to edit code yourself or something like that.

And, StonyYodelers, I'm sorry that you are having to post several thread, but I _DO_ appreciate the interaction with you.  I also really like having all of this info here, because I know that others will find all of it useful.  Thanks for your patience and willingness to help.

Yep, found that this morning thanks!
(I finished building the freeplay cm3 at like 2am local time, so when it turned on successfully I just closed the document like a dummy and assumed I was done so I went to bed lol)

I realized this morning that the thumbsticks and secondary triggers didn't work either so I figured it was a missing driver for the new board and found the stuff I missed in the install document.


No apologies needed! I could've just posted it all in one thread. The several threads are all on me lol. I just know how important it is for decent documentation for troubleshooting purposes so I figured making multiple threads has the potential to help more people than just myself! It's been a lot of fun working on these and you've been a huge help (and quick to reply!) the whole time, I really appreciate it.
