Hello @paul_at_go

Can you check with this image?

https://dl.khadas.com/products/vim3l/firmware/ubuntu/emmc/vim3l-ubuntu-20.04-gnome-linux-4.9-fenix-1.4-221229-emmc.img.xz

3

Worked great with that image. Are there only certain images or Fenix versions that work with the EM06? Is the RM500 from Khadas any different?

Thanks for the quick response!

4

The 4.9 kernel supports EM06 by default.

You mean RM500Q module? It is a 5G module.

5

Which Kernels support the RM500Q by default? We have a mix of EM06 and RM500s from Khadas.

6

The 4.9 kernel already supported.

7

I had a similar problem. So I made a simple script for compiling and installing the Quectel drivers for Linux kernels later than 4.9.

Thanks Caesar - that seemed to work great and made it easy to move up to a later Kernel.
