The Coral TPU driver has basically been abandoned by Google so if you are running a Linux kernel newer than 6.2 it will not function.
https://github.com/google/gasket-driver is the original driver which was archived on April 18, 2026
You can try the driver https://github.com/feranick/gasket-driver or https://github.com/dude84/gasket-driver-coral or search through the forks of the original gasket-dkms driver https://github.com/google/gasket-driver/forks
So in the future your options are to pin your kernel to 6.2, upgrade your hardware, hope that someone will keep a gasket-dkms fork updated for newer kernel versions, or make your own fork to do so yourself.
The feranick fork works just fine, even on kernel v7
That’s the worst part about it - the fix is so simple. Google just completely abandoned it.
It was just a single kernel function call on a single line with slightly modified arguments. Just make a small update and it works perfectly fine.
I spent much more time researching the fix than I did applying it. But now I have to rebuild and reinstall it every single time I update my kernel.
