Hello Team, I tried to buiild the MBPL driver code for qmi modem device. The module is unable to install and got the below error while doing insmod. ~/mbpl-driver/usb$ sudo insmod qcserial.ko [sudo] password for sbaby: insmod: ERROR: could not insert module qcserial.ko**: Unknown symbol in modul…

yes I did. Below is the steps I followed. got code from here : Mobile Broadband Package for Linux (SDK, Drivers, Documentation) sudo make sudo make install i got the below files: built-in.a modules.order qcserial.c qcserial.mod qcserial.mod.o qmi_wwan.c qmi_wwan.mod qmi_wwan.mod.o…

then “sudo make install” already installs in your platform, you don’t need to insmod again

okay. lsmod did not shows any modules loaded.

here is the complete logs. it did not say any difference . with make install or without make install , both time it fails with "unknown symbol in module: :~/mbpl-driver/usb$ sudo make [sudo] password for sbaby: make -C /lib/modules/5.4.0-150-generic/build M=/home/sbaby/mbpl-driver/usb modules m…

did it enumerate /dev/ttyUSB port when you connect EM9191 to your platform?

Are you testing in ubuntu pc? Does your module work in windows? Any message show in dmesg in linux when you connect usb?

I am testing on intel atom processor running ubuntu 5.15 kernel. (using yocto build env) I did not tested in windows. I will send the logs tomorrow.

Suggest to test in windows and ubuntu pc for comparison

Do I need to enable any Linux kernel specific config flags for MBPL to work ? Are we suppose to see any kernel modules loaded as part of lsmod after I execute “sudo make install “ ?

no . It did not enumerate /dev/ttyUSB port when I connect EM9191 to one of the USB port.
