@EnziinSystem I concur and I followed those exact steps.
I have also tried installing the releases of gasket from Freneck's repo both of which do not seem to be aligned with the 6.6.30 headers.

@askpatrickw @EnziinSystem I'll get the tutorial for all AI boards uploaded to our docs website today

When you're done, please give us the link here.

Thanks.

This covers the DMKS drives as well as updating the kernel with rpi-update and installing the headers with rpi-source (since 6.6.30 is not live via apt yet.

@mikegapinski, I'd post a comment on your post, but no way to do that.

The kernel update steps result in the following errors, for me anyway.

I opened a bug on this last one as the docs are not helpful.

That is why I linked a fork of RPI-Distro in my tutorial sudo wget https://raw.githubusercontent.com/jgartrel/rpi-source/master/rpi-source -O /usr/bin/rpi-source

The command rpi-source --tag-update blocks it from being overwritten with the official one

@mikegapinski ... yes. I did use all the commands in your tutorial.
I was just being brief in my notes. Here you can see the full commands don't work.

@mikegapinski Hi Mike,
Thank you very much for your guide.

I was hoping you can help me to sort out why after all of the steps I don't see the TPU available as apex?

➜  ~ ls /dev/apex_*
zsh: no matches found: /dev/apex_*

I've got the dual-core M.2 A+E TPU and RPI5 with A+E PCIE head, Mcuzone.

Following your steps, I've upgraded to 6.6.30-v8+ #1763 SMP PREEMPT Mon May 13 17:50:31 BST 2024 aarch64

Trying different things around I suspect that maybe my release of the kernel is problematic, not supported by the driver?.

I ran the kernel headers installation ahead of this attempt.
Just like I previously downloaded and installed drivers from Google with no visible errors.
Surely tried rebooting multiple times.

Overall, the TPU is recognisable (maybe at least 1 core, I'm not sure. But it's less important at the moment):

Many thanks.

Your kernel headers for kernel 6.6.30-v8+ cannot be found Remove the Linux kernel downloaded by rpi-source and retry - the install didn’t go through. .30 kernel will be stable soon so headers will be available via APT Wysyłane z aplikacji Outlook dla systemu iOS<https://aka.ms/o0ukef>

@mikegapinski you're the best.
It did indeed help. The driver is working now.

So now I'm wondering what exactly am I missing to see both cores (as I remember they're supposed to be displayed separately).
I'll try to look into it myself, however if you're got some ideas, you're welcome :)

@sadontsev you need the HAT Ai Dual if you want to see two accelerators. This board has a PCIe switch for the Dual Edge TPU

@mikegapinski yeah, thanks. I was promised by the seller that mine would support it. But maybe it was a trick.

Here's some info

@mikegapinski yeah, thanks. I was promised by the seller that mine would support it. But maybe it was a trick.

Here's some info

In theory it does support it, but not fully. The Dual Edge variant needs a dedicated board

@mikegapinski yeah, you're right.

Upd, maybe I found what's wrong:
$ dmesg
...
[ 5496.544355] apex 0000:01:00.0: RAM did not enable within timeout (12000 ms)
[ 5496.544364] apex 0000:01:00.0: Error in device open cb: -110
...

Which may related to the connection issue. See comment section here
Yet, it was too early to celebrate. For whatever reason, the TPU cannot be identified yet either by Frigate or simple Python script (bare metal w/ pyenv or via Docker).
I even tried a clean OS installation on a spare card but didn't help.
I appreciate if someone can suggest the next steps here:

This can happen if the board you use does not have proper routing and a high quality FPC cable: raspberrypi/linux#6126

That is why the kernel overlay is not for coral itself, it does not work on all PCIe hats.

You can check for dmesg errors, but I think this is the problem

FYI: There is an updated rpi-source which fixes the "ERROR: Unexpected processor 4 (use --processor argument)" issue https://github.com/RPi-Distro/rpi-source I installed from master and it fixed it on my RPI 5.

I ran lines 1-46 Up to adding the user to the group and then rebooted.

Hi, I found out that when I upgrade to 6.6.31+rpt-rpi-v8

~ $ sudo lspci -vvv|grep -i MSI-X
	Capabilities: [d0] MSI-X: Enable- Count=128 Masked-
	Capabilities: [b0] MSI-X: Enable+ Count=61 Masked-

this will fail [d0] MSI-X: Enable-, going back to 6.6.20+rpt-rpi-v8 everything will work again (as in the sample in pycoral will run). Not sure if its related to your issue. Anyone know why it breaks when upgrade to 6.6.31+rpt-rpi-v8?

Following up on this, i use apt-mark to lock the kernel:

~ $ sudo apt-mark hold linux-headers-rpi-2712
linux-headers-rpi-2712 set on hold.
~ $ sudo apt-mark hold linux-headers-rpi-v8

after upgrade the kernel remain the same but the same issue occurs, so its some other package that got updated and cause the MSI-X issue

This can happen if the board you use does not have proper routing and a high quality FPC cable: raspberrypi/linux#6126

That is why the kernel overlay is not for coral itself, it does not work on all PCIe hats.

You can check for dmesg errors, but I think this is the problem

The Pineberry board has just arrived and it solved all of my problems. Works like magic.

It just works, both cores are visible and usable.

I noticed a new kernel version is available. Do you know if it included everything required to let the hat work just from the box?

Hi @sadontsev can you please share which method you have followed? I checked in the Pineborads website, and it says to update the kernel. I am a little bit confused. Do I have to do that or not?

Thanks in advance

I use this board Dual Edge Coral TPU Bundle for Raspberry Pi 5 with Home Assistant and Frigate

Error! Bad return status for module build on kernel: 6.6.36-v8+ (aarch64)

This is the actual error, the kernel module failed to build. Since you are using Home Assistant OS the steps could be different. Can you post the contents of /var/lib/dkms/gasket/1.0/build/make.log? The script you used for install is slightly outdated too, please refer to our install guide: https://pineboards.io/blogs/tutorials/how-to-configure-the-google-coral-edge-tpu-on-the-raspberry-pi-5. If you get stuck anywhere I'll reproduce and update our tutorial as well.

As far as I remember 6.6.30+ is now available from apt since it is also required for the Hailo 8L TPU, so kernel upgrade does not require rpi-source

Hello, @19leva89 I have completed that step and now when I am going to install Pycoral I cannot install it have you tried this one? I want to run Ultralytics YOLO v8.

Thanks in advance
