Install of PCie drivers for coral TPU

[Mikey6283]

Hi

The Pcie module is installed in the host hardware however I am unable to install Coral pcie drivers from coral website as it is giving errors as below :

Any help would be appreciated with examples please.

Hi,

the issue is probably just caused because you never run an actual apt update, so the package index of the newly added repo isn't yet available and known to the system.
You tried with using sudo, but as sudo is apparently not installed it failed:

sudo apt-get update
-bash: sudo: command not found

If you're already logged in as root you do not need sudo anyway, just execute:

apt update

and then retry the installation.

I have been able to install the repositories however i still get the error that no such file or directory?

root@pve:~# lspci -nn | grep 089a
03:00.0 System peripheral [0880]: Global Unichip Corp. Coral Edge TPU [1ac1:089a]
root@pve:~# ls /dev/apex_0
ls: cannot access '/dev/apex_0': No such file or directory
root@pve:~#

Is there a solution so that i can proceed ?

First note that in general this is pretty much unrelated to Proxmox VE and maybe better solved in a forum/support channel of the Vendor or a in general TPU related forum.

Still, did you reboot the host after installing the dkms module, or at least explicitly loaded it with modprobe?
As something needs to actually create the device node in /dev.

Any relevant output to that device in the kernel message buffer, check the dmesg command.

Yes did apt update and reboot after installing dkms and still it is not finding

I am still having issues , i thing i have noticed is that when i use the command" find /sys/kernel/iommu_groups/ -type l"

I was trying to get this working today. I noticed when the kernel module was installed, it complained about missing kernel headers, so I ran this (which will depend on the current kernel version you are running):
apt install pve-headers-5.15.35-1-pve

Once complete, you can reinstall the module:
apt-get install --reinstall gasket-dkms

Then I was able to simply load the modules:
modprobe gasket modprobe apex

Now I have the proper device:
root@proxmox:~# ls -l /dev/apex_0 crw-rw---- 1 root root 120, 0 Jun 19 20:09 /dev/apex_0

Hope this helps someone. Good luck!

so I ran this (which will depend on the current kernel version you are running):
apt install pve-headers-5.15.35-1-pve

If you are on the latest kernel and do not need a specific/older headers-version, you can simply install the pve-headers metapackage.

Thanks for the tip!

Also, I'd recommend those who were trying to get this working to check out the following thread as it was very helpful in getting this working:
