Please describe your issue below:

VIM3 cannot see anything from M.2 PCIe socket. I tried M.2 SSD but VIM3 cannot see it. I verified my M.2 SSD on another computer and it works.
Also I have an AI aceelerator chip and I loaded all drivers of it, then I put it on Khadas PCIe but it could not recognize it. I also verified my AI accelerator on another PC and it also work. What should I do?

Hi @egecancetin

You need to enable the PCIe by switching the port mode.

$ echo 1 > /sys/class/mcu/usb_pcie_switch_mode
$ sudo reboot
