I am trying to test the QMI mode on MC7710, but I am always getting “Unable to find device…”
when running Connection Manager sample application.
I am using SLQS03.00.02, binary only version.
I have compiled GobiSerial and GobiNet successfully. I switched MC7710 to QMI mode and
loaded modules and I get:
GobiSerial 1-1.3:1.0: GobiSerial converter detected usb 1-1.3: GobiSerial converter now attached to ttyUSB0 GobiSerial 1-1.3:1.2: GobiSerial converter detected usb 1-1.3: GobiSerial converter now attached to ttyUSB1 GobiSerial 1-1.3:1.3: GobiSerial converter detected usb 1-1.3: GobiSerial converter now attached to ttyUSB2 usb0: register 'GobiNet' at usb-isp1761.0-1.3, QmiNet Ethernet Device, 2a:60:5c:bb:1d:ca creating qcqmi0
I have checked that all three /dev/ttyUSB[0-2] are working and also created /dev/qcqmi0 with
proper major and minor numbers.
I have copied connectionmgrarm and slqssdk on my target and when I run:
> ./connectionmgrarm SDK/build/bin/arm/slqssdk Unable to find device..
I also tried using strace on both binaries, but I cannot find any open system call
to /dev/ttyUSBX or /dev/qcqmix.
Went trough “Linux QMI SDK Application Developer Guide.pdf” but it seems I have
done everything right, well except for building the SDK since I do not have the
What am I doing wrong?
Thank you and Regards,
