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)
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
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:

did it enumerate /dev/ttyUSB port when you connect EM9191 to your platform?
no . It did not enumerate /dev/ttyUSB port when I connect EM9191 to one of the USB port.
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, you need to connect usb of module, otherwise, the kernel module will not be loaded
Thank you . I will connect EM9191 to the usb and will check if it is loaded.
This is the log from dmesg after connecting EM9191 to intel atom board running ubuntu
May I know if there is any tool to test in windows to conmfirm the modem is working correctely.
I will test in windows and native linux (ubuntu ) too
on ubuntu PC i got the belwo messages from dmesg.

How do I make sure the modem is connected and accepting AT commands ?
I also tried to lauch the below application but failed

*bimTransport_Initialize failure
MbimTransport_Initialize failed for /dev/cdc-wdm0
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
Can I know any tool for windows to check the AT commands
i used the tool called tera term
You can also use Putty
