Request : quectel rm520n-gl 5g sub-6 arm64 hmi pci driver

[wjsdidgh2536]

hello.

Is it possible to get the MHI-PCI driver based on arm64 architecture for quectel rm520n-gl 5g sub-6 module ?

Please share the latest driver version that supports Ubuntu 20.04 version.

Hello.
Thanks for your suports

But something happened to me.
I got the following error message while generating the make file.

user@avg:~/Downloads/pcie_mhi$ sudo make

It should be
make ARCH=arm64

[wjsdidgh2536]

Is there a manual for making the module aware of the PCI slot?

Hi, thanks as always for your help.
Below is the error I got while building using the make ARCH=arm64 command.

My PC is running Nvidia-Jetpack6.1 (Ubuntu22.04 , aarch64)
with Nvidia-Jetpack6.1 (Ubuntu22.04 , aarch64).

Can you give me some ideas to solve this problem ?

[Bean.Wang-Q]

It is because your Linux kernel have added the kernel configuration related with the IPQ807x.
You need modify the pcie_mhi driver to make it ignore the rmnet_nss.
