How to install the driver under the Ubuntu 24.04 with Rasberry PI5

IoT Modules 5G Module
1

I install ubuntu 24.04 on the Rasberry Pi5 with RM530n-GL, now can recognize the module with command “lspci”

however, can’t see any related network interface in the system

I guesss we need to manually install driver on the Ubuntu system.
Now I got the Quectel_QConnectManager_Linux_V1.6.7.zip/QFirehose_Linux_and_Android_V1.5.zip/Quectel_Linux_PCIE_MHI_Driver_V1.3.8.zip/Quectel_Linux_Android_GobiNet_Driver_V1.6.5.zip/Quectel_Linux_Android_QMI_WWAN_Driver_V1.2.9.zip, but I don’t know how to install that driver.

Could someone help to ensure which driver need to be install, and how to install?

Finally, i need to use QconnectManager to dial the 5G services.
Thanks!

Could you tell the the Linux kernel version？
Normal if the RM530N is already working in PCIe EP mode, it should be working with the quectel-CM and the pcie_mhi driver.
But for the latest kernel version, the pcie_mhi_generic is already there and the pcie_mhi might fail to be installed.
If the driver is already in PCIe EP, you don’t need the USB driver such as GobiNet or QMI_WWAN.
Please show
lspci -vvv
and show the /dev/.
I am not sure whether the ModemManager is already there. The ModemManager is conflict with the quectel-CM.

@Bean.Wang-Q the kernel is Linux pi5 6.8.0-1036-raspi, and i had installed the pcie_mhi_generic and ModemManager, however, when install pcie_mhi, it is failed, below is the info

It already match the driver Kernel modules: mhi_pci_generic.
The pcie_mhi and pcie_mhi_generic cannot work at the same time.

5

It seems that the build env is not correct.

6

Your guys sent me five driver file, i firstly install the mhi_pci_generic, currently for these two questions:

  1. pcie_mhi and pcie_mhi_generic can’t work at the same time
    – as I can’t see the interface info, whether i need to uninstall the pcie_mhi_generic, then install pcie_mhi?
  2. It seems that the build env is not correct.
    – how i need to fix the env issue?

Thanks!

pcie_mhi_generic is not the driver provided by Quectel. It is the native driver from the Linux kernel.
Quectel just provide the pcie_mhi driver.

It looks like the code is asymmetrical. I don’t know if you’ve modified the code.

8

i didn’t modified any file, in order to recover the original env, i reinstall the ubuntu 24.04 via Rasberry PI5, now the Quectel can be recognize under the USB, even if i add the “dtparam=pciex1” and change the AT command,

OK

As that is the pure env, could you share some guide for me, to step by step complete the setup?

Env is below:

USB 3.0 is much easier than PCIe.

It seems that PCIe is not recognized now.

Maybe you can try
dos2unix *
Make sure all the files are Unix like.
I don’t have the Rpi5 and I am sorry that I cannot show you how to compile it on your device.
I can try test it with cross compiler.

  strlcpy (info->driver, "pcie_mhi", sizeof info->driver);
  ^~~~~~~
  strscpy

And just change the strlcpy to scrscpy.
Then we can get the pcie_mhi.ko.
But I think it might not work for you.

For Ubuntu 24.04 we is difficult for us to change the vmlinux.
