I tried to connect a PCI-e sound card through an adapter. Kernel 4.9 produces a similar error in the logs. But on the mainline kernel (5.5 rc2), the sound card was determined. Apparently, you still need to backport the latest changes related to PCI-e.
I just checked, I will try to buy one and feedback here.
I made ubuntu 20.04 image with fenix with mainline linux
uname -a
Linux Khadas 5.6.0
cat /sys/class/mcu/usb_pcie_switch_mode
1
so it looks like I have pci-e mode
but
lspci -vvv
is empty and I don’t see any host bridge
and no sign of meson pci-e in dmesg
any idea?
I would like to connect pci-e dvb-t tunner
btw

Any progress on connecting coral M2 card to VIM3/L pcie slot?
Any updates on VIM3x and the Coral module? @numbqq
I just bought your VIM3L and tried on VIM3L_Ubuntu-server-focal_Linux-5.7-rc7_arm64_SD-USB_V0.9-20200530 : after installing the B+M module and the Coral driver lspci reports nothing, nothing relevant in dmesg.
I still have no luck to make it work…
Thanks @numbqq for the update.
So you have the Coral M.2 B+M module purchased but you can’t make it work with VIM3x? Have you tried it with your other Khadas boards, especially the ones without built-in NPU, like Edge-V?
What power supply are you using? In my case, once I connect the M.2 module, install the driver and restart, my VIM3L doesn’t boot - I may have to try a beefier power supply (say 12V 5A) as the TPU module specs list current demand up to 3A.
After toggling USB 3.0 -> PCIe I see this in dmesg:

Someone reported on another forum that this -110 error had gone away with fixes in 5.8.x, can we count on updated Khadas images soon?
Same issue and syslog as OP on my VIM3L with Linux Khadas 4.9.241 #8 SMP

Anything else can be checked to troubleshoot this @numbqq?
What’s the status of this issue now? And any plan for this issue? (It lasts for almost 2 years.)
Following is the the FW running on my VIM3. PCIe Wi-Fi card inserting to M.2 slot still hit this issue.
Would you please share a working FW image (Ubuntu) that I can work as a WAR.
Thanks,

I am also waiting for the support.
Hi @Vignesh_Raja
We just ordered a Coral, @numbqq and @Frank will try to fix this issue once the package is delivered.
Good day!

Is there any solution to this problem?
@brunovollmer @David_Zou @Vignesh_Raja Mainline kernel can use coral now. 4.9 kernel still haven’t run it.
@Frank I have used the Google USB Coral with the latest Ubuntu Image and all the code samples from Google Coral works within a matter of minutes. Thanks for it.
Good to hear that. Will test it on Monday with the mainline kernel!
@brunovollmer It is known that there is a bug that will make the SSD unusable, but it will not affect your testing of the coral for the time being. The test should refer to the following steps
I made a statement inside, how to use
