Hi,
I have flashed new image and could succesfully install Coral TPU on Khadas VIM3 at M.2 port. But when running the demo app of Coral I get following error:

khadas@Khadas:~/coral/pycoral$ sudo python3 examples/classify_image.py --model test_data/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite --labels test_data/inat_bird_labels.txt --input test_data/parrot.jpg

During handling of the above exception, another exception occurred:

Could you please help me out?

@ms_de Which one image you used ?

4

VIM3_Ubuntu-gnome-focal_Linux-4.9_arm64_EMMC_V1.0.9-211217.img

And Boot VIM3.uboot-mainline.emmc.aml

5

@ms_de Just mainline kernel can use coral

6

what do you mean by “mainline kernel”? What should I do?

7

I found the mainline kernel images here: Khadas VIM3 Ubuntu Firmware | Khadas Documentation

But is it correct, we cannot install these images on emmc?

8

@ms_de You can install it to usb or sd card . then after the system boot, you can run this command sudo emmc-install to install your system to emmc

9

ok great, thank you!

10

@ms_de If you use mainline firmware. Don’t forget this

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…

@ms_de You can use kbi command in uboot to switch to USB3.0

13

I need to have serial connection?

14

@ms_de Yes. If you don’t have a serial tool. you can try krescue.

15

ok thank you, let me try both ways.

16

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 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.

@ms_de Did you use the least release firmware ?

http://dl.khadas.com/Firmware/VIM3/Ubuntu/SD_USB/VIM3_Ubuntu-gnome-focal_Linux-5.16-rc2_arm64_SD-USB_V1.0.9-211217.img.xz

19

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.

20

@ms_de I will check it later
