ok great, thank you!
thanx I did it, and it has installed dkms.
But I cannot see any device when giving command lspci -nn | grep 089a
I want to check if PCIE is enabled, but the app for switch USB3 - PCIE is not running on the desktop. And the command cat /sys/class/mcu/usb_pcie_switch_mode not running because folder mcu is not there.
Do you have another idea?
BTW, I see that my USB Keyboard is not detected correctly when I boot, I need to replug the USB dongle then it works…

I need to have serial connection?
ok thank you, let me try both ways.
I have checked via Serial, the PCIE is already activated. I activated again and rebooted. But the PCIE is still not recognized. very strange.
Before when I was working on the other image VIM3_Ubuntu-gnome-focal_Linux-4.9_arm64_EMMC_V1.0.9-211217.img then I could see the PCIE device, so the device should be not broken or so. Do you have any idea?
I have run this:

Kernel driver in use: pcieport
I found similar issue at this forum: Google Coral M.2 at mini PCIe not detected · Issue #334 · google-coral/edgetpu · GitHub
Maybe our issue is related to BIOS also?
I have checked this, seems that pcie driver is not loaded:
khadas@Khadas:~$ ls /dev/apex_0
ls: cannot access ‘/dev/apex_0’: No such file or directory
Just FYI I have installed OS to Emmc but same issue.
yes exactly the same firmware
we use the M.2 slot for PCIE, maybe that is the issue? The USB version of Coral is working.
Hi Frank,
happy new year. Did you got time to check it out?
@hyphop
How to add more resolutions to Ubuntu focal with 4.9 kernel installed on emmc?
For me it only allows 1920x1080 and I want 1366x768 option.
I see that now, the ts050 doesn’t turn on before the plymouth boot splash,
its turned off, and when it turns on I’m presented to the tty console,
however when turning off the device, the bootsplash can be seen
is there a fix for this ?
Did you find a solution to this? I am having exactly the same issue
Did you have time to check it out? Same problem on my side. I switched to PCIe via Krescue and it can’t detect the TPU. Worked fine with the 4.9 kernel
@brunovollmer @ms_de We had check it last week. I work fine with mainline. But 4.9 kernel can’t be use
Any idea why it does not show up when I search for it? For 4.9 it shows up but then other problems stop it from working.
Could you post your steps you have taken?
Thanks
@brunovollmer Did you switch to PCIE?

And did you follow this doc ?
