RM520N-GL drivers

Is it possible to get RM520N-GL quectel linux drivers?

Thanks a lot

Hi @imthernet,

if you’re familiar with (re-)building your own kernel modules you could use these mainline Linux kernel patches



Yes, that worked for me. Thank you very much.

Hey, can you explain how to install the linux drivers using these patches? I am a new user.

Hi. You don’t need to rebuild the kernel. I solved it with binding current kernel drivers to existing USB ports.

echo 2c7c 0801 ff > /sys/bus/usb-serial/drivers/option1/new_id
echo 1-1.3:1.4 > /sys/bus/usb/drivers/option/unbind
echo 2c7c 0801 ff > /sys/bus/usb/drivers/qmi_wwan/new_id

Take USB ID 1-1.3:1.4 from syslog. It means 4th interface (port) of the usb device sitting on 1-1.3. I.e. it is QMI WWAN+QMI CDC.

so you will get wwan0 , /dev/cdc-wdm0 and /dev/ttyUSB2 (AT port).
