Coral EdgeTPU m.2 (for Frigate) not able to install on 24.10 (Electric Eel)

Apps and Virtualization

check how many lanes that slot has, you need two lanes to use a dual TPU, an adapter won’t help, even with lane splitting/bifurcation AFAIK

in my case the mobo m.2’s are all single lane so I had to get the single tpu

EDIT: based on cursory research, if you use the slot that’s meant for the SSD you may be able to make it work, but the one that had the WLAN card is single lane so at absolute best you will get 1 TPU (and most likely neither)

FWIW using the 4x slot for the dual TPU is a waste because it will only consume 2 lanes, I’d recommend just getting a single and putting it in the WLAN slot

anyone tested Coral EdgeTPU on FANGTOOTH (25.04)?

EDIT:
Tested now and was successfull.

my steps were:

sudo visudo

→

#Defaults log_subcmds

then used the steps from @campagnolo - BUT: be sure you call the debuild with sudo:

systemd-sysext unmerge
install-dev-tools
apt install dkms devscripts debhelper dh-dkms -y
git clone https://github.com/heitbaum/gasket-driver
cd gasket-driver
sudo debuild -us -uc -tc -b -d                        <-- must use sudo here
cd ..
dpkg -i gasket-dkms_1.0-18_all.deb
systemd-sysext merge

# if everything was successful
reboot

I followed this completely on a fresh Fangtooth install and it consistently fails at the sudo debuild step. Error I receive is:

sudo: process 1717401 unexpected status 0x57f
dpkg-buildpackage: error: debian/rules clean subprocess was killed by signal 9
debuild: fatal error at line 1182:
dpkg-buildpackage -us -uc -ui -tc -b -d failed

Looking inside debian/rules:

include /usr/share/dpkg/pkg-info.mk

%:
dh $@ --with dkms

override_dh_install:
dh_install src/* usr/src/gasket-$(DEB_VERSION_UPSTREAM)/

override_dh_dkms:
dh_dkms -V $(DEB_VERSION_UPSTREAM)

override_dh_auto_configure:
override_dh_auto_build:
override_dh_auto_test:
override_dh_auto_install:
override_dh_auto_clean:

Something in the rules is getting killed.

Not having luck on Fangtooth either (an upgrade install, things worked fine on Electric Eel).

So far I’m trying to just do the same steps again and the following happens when doing install_dev_tools:

sudo: process 1717401 unexpected status 0x57f

I discovered this error is due to trying to run the script from the boot pool.

Create a folder on the storage pool for doing this compilation. For some reason, Fangtooth doesn’t let you run scripts that are stored on the boot pool.

I’m now at the point where I’ve got the .deb package to build, but can’t get it installed!

Success! Coral M.2 pci TPU working in Frigate App on TrueNAS Fangtooth
What a hassle though.
After editing the Frigate app config to passthrough the device:
host device:
/dev/apex_0
container device:
/dev/apex_0

it’s working

Follow-up, working on Truenas Fangtooth (25.04.0). Brief notes:

has anybody looked at creatinga sysext for these drivers?
(for example cloning a boot partion with no dev tools installed, rebooting to the new part, creating the sysext and saving it to one of the non-boot pools) then rebooting to the unmodified boot image and applying the sysext?
