Beaglebone Ai Heating Issues

While experimenting with the device, I found that the board would shutdown without warning. The reasons is...

Now I tried a number of combos like us the USB tether, connect with display(yes I have the cursed microHDMI cable) and use standalone but every time, it just overheats if I do anything.

Idle temps are high too. Was wondering if I got a bad board or is it everyone?

Hi ipv1 , I looked into this and this is a known issue: BeagleBone AI - Frequently Asked Questions (FAQ) They recommend adding a larger heat sink and cooling via fan.

Hi shabaz - I've made a first prototype which seems to fit quite well. Packing out the top spacing by one extra washer was enough to get it to grip the existing heatsink fins. I'll make a bracket over…

The 48 to 49 deg. C temperatures while idle I was seeing were pretty much what I expected to see. While testing I tried starting up the web browser and even though the CPU monitor
showed from 60 - 100 % usage most of the time I too only saw a couple of deg. C rise. At one point while the browser was starting up the terminal I was using to read the temperatures
completely froze up solid for 10 to 15 seconds. The combination of these two things made me wonder if some CPU frequency throttling was occurring where it had not before. The
software I am running on the AI was fully upgraded Friday evening and there was a kernel update. Next time I get the chance I am going to look around in /sys to see if I can find where
the core frequencies can be read from.

I tried going back to the discussion you mentioned and attaching it there but I could not find a way to do it. I don't think I tried editing it though so I will go back and give that a try.
I have an account on github but as far as I know it only allows me to clone public projects from it. I would really like to just post it here if I can.

I discovered they have a new default called policy0. Within that policy0, the max GPU frequency is set at 1 GHz value most of the time for both processors. So take that into consideration.

OK. Its official. My BB-Ai is either dead or I have not idea what is wrong with it.

I connected a serial cable to my PC and tried to boot- Nothing.
I tried with SDCard Images- Nothing
Keep individual buttons pressed and then supply power- Nothing.

The green LED lights up but that is about it. I think it may have actually burned out!

How about only a USB-A to USB-C cable to your computer with no SDCard?

Had you connected anything to the black pin headers before it became unresponsive?
