linux Gasket driver required for Google Coral on Pineboards HatDrive! AI doesn't install on 6.12.20

Describe the bug

I'm using a Raspberry Pi 5 with a Pineboards HatDrive! AI and Google Coral M.2 Accelerator A+E Key. Unfortunately, this is now a dead link: https://pineboards.io/blogs/tutorials/how-to-configure-the-google-coral-edge-tpu-on-the-raspberry-pi-5 I'm trying to install the gasket driver but it's failing using the following 2 methods.

Steps to reproduce the behaviour

Method 1: sudo apt-get install gasket-dkms -y

Error:

Maybe this bug is not for here and is for the Google gasket-driver repo? I have built and installed the package using info found here: https://github.com/google/gasket-driver/issues/36 which all seemed to work in terms of build and install. However, when I update my Frigate config to use Coral the system doesn't behave - I can't view the System Metrics page to see the inference load switch from the CPU to the TPU, for example. Even login is temperamental. Disable the Coral in the Frigate config and all back to normal - but with excessive load on the CPU hence trying to get Coral TPU installed.

dmesg returns apex 0001.03.00.0: Couldn’t initialize interrupts: -524

Apr 23 '25 17:04 MappyMatty

You could try with dtoverlay=pciex1-compat-pi5,nomip.

Apr 23 '25 18:04 pelwell

Hi guys, is there any update on this issue?

Apr 25 '25 20:04 hungnguyen167

Thanks for the suggestion @pelwell I've tried dtoverlay=pciex1-compat-pi5,no-mip by itself and in combination with dtoverlay=pineboards-hat-ai and after a reboot I get the same apex 0001.03.00.0: Couldn’t initialize interrupts: -524 in both scenarios.

Apr 26 '25 09:04 MappyMatty

With both overlays removed and a reboot I get a different message from dmesg of apex 0001:03:00.0: Couldn't initialize interrupts: -28. My next step will be to downgrade to 6.6.x per info at https://gist.github.com/dataslayermedia/714ec5a9601249d9ee754919dea49c7e

Apr 26 '25 09:04 MappyMatty

I'm having exactly same issue with kernel 6.12.20 and gasket driver pulled from git repo and llseek modified. The accellerator does not work with frigate and I get dmesg: kernel: apex 0001:03:00.0: Couldn't initialize interrupts: -524

Finally I ended up with restoring kernel 6.6.74 via apt, I've had to remove wireguard-tools and wireguard-modules to be able to remove latest kernel. apt install --reinstall raspi-firmware Then compiled wireguard-tools by hand, to restore my VPN.

Btw fortunately there is Internet Wayback Machine to recall installation process for the board. How to configure the Google Coral Edge TPU on the Raspberry Pi 5

Apr 29 '25 08:04 mattblonski

Latest update: my PCI Edge TPU now works with linux-image-rpi-v8 kernel package, ver. 6.12.25+rpt-rpi-v8 and https://github.com/google/gasket-driver/issues/36 modification.

Hopefully future kernel releases will not cause the same issues.
