PCIE Google Coral Install Instructions

[Jake_Simek]

I wanted to go ahead and show how I was able to get the pcie google coral functioning on my pve machine. It has been a complete nightmare for me, and it seems like it has been for many others as well. I am no professional, but these are simply the commands I used to get this running. There are several things that most likely could have been consolidated, like the reboots and apt installs, but this is what is tested and works for me.


This is the output of lscpu on my machine for reference

Coral Install
# This was all done from root user

#First verify your machine has MSI-X by running this command
lspci -vv | grep MSI-X

#Also make sure secure boot is disabled if you have that option



apt update && apt upgrade -y

# Not needed, just makes copy and pasting cmds easier
apt install sudo -y

echo "deb https://packages.cloud.google.com/apt coral-edgetpu-stable main" | sudo tee /etc/apt/sources.list.d/coral-edgetpu.list

curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -

wget -O- https://packages.cloud.google.com/apt/doc/apt-key.gpg | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/coral-edgetpu.gpg

apt update

sudo apt-get install gasket-dkms libedgetpu1-std -y

#likely not needed, but I was just being over cautious
reboot now


apt remove gasket-dkms -y

apt install git devscripts dh-dkms -y

cd /home

git clone https://github.com/google/gasket-driver.git

cd gasket-driver/

debuild -us -uc -tc -b

cd ..

apt install pve-headers -y

dpkg -i gasket-dkms_1.0-18_all.deb

cd

apt update && apt upgrade -y

reboot now



# Verify the drivers are functioning properly

lspci -nn | grep 089a

ls /dev/apex_0



I hope this helps someone, if you have a question let me know, I am no expert, but I will try to help.

I feel your pain, been there.

If you haven't already, pin a kernel to 6.2 version -- lots of issues with coral/apex under 6.5 kernels. Do that and you don't have to build your own version, the "off the net" directions work fine.

None.
