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 module\*\* ~/mbpl-driver/usb can I know of there is any kernel configuration or some other issue? Regards Simon ---

did you type “sudo make” and “sudo make install” in your platform? ---

yes I did. Below is the steps I followed. got code from here : [Mobile Broadband Package for Linux (SDK, Drivers, Documentation)](https://source.sierrawireless.com/resources/airprime/software/mbpl/mbpl-software-latest/#sthash.yQDpV6EF.dpbs) 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 readme.txt usb-wwan.h usb\_wwan.mod Makefile Module.symvers qcserial.ko qcserial.mod.c qcserial.o qmi\_wwan.ko qmi\_wwan.mod.c qmi\_wwan.o usb\_wwan.c usb\_wwan.ko usb\_wwan.mod.c ---

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

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, you need to connect usb of module, otherwise, the kernel module will not be loaded ---

I can see /dev/ttyUSB0 enumerated in your ubuntu pc, you can use minicom to send AT command BTW, here is the USB driver in Windows: [https://source.sierrawireless.com/resources/airprime/software/sdx55-windows-drivers-build-5154/#sthash.NcVh1G9l.dpbs](https://source.sierrawireless.com/resources/airprime/software/sdx55-windows-drivers-build-5154/#sthash.NcVh1G9l.dpbs) ---
