Please describe your issue below:

Good day!

  1. I can’t enable “M.2 Slot PCIe 2.0 (x1 lane), supports M.2 2280 NVMe SSDs” for activativating second ethernet interface (eth1).

Hello @nkt.sv97

Maybe the driver is missimg, can you try to upgrade the kernel and check again?

wget https://dl.khadas.com/.test/vim4/linux-dtb-amlogic-5.15_1.6.7_arm64.deb
wget https://dl.khadas.com/.test/vim4/linux-image-amlogic-5.15_1.6.7_arm64.deb
sudo dpkg -i linux-dtb-amlogic-5.15_1.6.7_arm64.deb linux-image-amlogic-5.15_1.6.7_arm64.deb
sync
sudo reboot

After reboot please check again, and also provide the kernel log.
