Hi Aleksander, I have backported the driver and loaded it into my target. I could see the following interfaces in the target/ # ls -l /dev/mhi0_QMI # ifconfig mhi_hw0
I have executed the qmicli and was able to reach the modem. However, the ModemManager is up but the modem is not getting detected. Is that because of libgudev as I built the ModemManager with --without-udev ? *# qmicli -d /dev/mhi0_QMI --dms-get-manufacturer* [01 Jan 1970, 00:06:32] -Warning ** [/dev/mhi0_QMI] couldn't detect transport type of port: unexpected port subsystem [01 Jan 1970, 00:06:32] -Warning ** [/dev/mhi0_QMI] requested QMI mode but unexpected transport type found [/dev/mhi0_QMI] Device manufacturer retrieved: Manufacturer: 'QUALCOMM INCORPORATED' Note : I am also trying to backport the diver from the 5.15 kernel.
