Thanks very much. Is it possible to sign the kernel module? I’ve got an error saying that ```
module verification failed: signature and/or required key missing - tainting kernel.

You can compile the pcie_mhi with the Linux kernel.
For how to sign the kernel module, I don’t know how to do.

@Bean.Wang-Q Got it. It is fixed. Just for anybody else with the problem, i had a new Lenovo laptop which has 520N-GL PCI 5G module and i came with FCC locked (not applicable to be because i am in Malaysia)

Check if your 520N-GL is FCC unlocked:

sudo mbimcli -p -d /dev/wwan0mbim0 -v --quectel-query-radio-state

And here is how i enable software radio (after finding it was FCC locked by above command):

sudo mbimcli -p -d /dev/wwan0mbim0 -v --quectel-set-radio-state=on

@Bean.Wang-Q, Could you send me the Linux PCIe Driver for RM520N-GL, I use on RK3588s platform, need the driver for transplant.
