I’m building my kernel using the following steps: //get latest kernel source
I did the test above because if I compile the kernel myself and enable PPP and USB ACM options as indicated in the article above, then I am unable to see the modem mount as a ttyUSBx or ttyACMx device. So, obviously, the stock image I installed does not support ppp filtering. Protocol-Reject for 'Compression Control Protocol' (0x80fd) receivedĭiscarded non-LCP packet when LCP not open Script chat -v -f /etc/ppp/chat/vodafone-3g.chat finished (pid 711), status = 0x0 Using the stock image (which I now doesn’t provide ppp or acm support), I was able to communicate with the modem, but obviously it didn’t work. So, I abandoned the ofono approach for now and have been trying to just get it working based on the following article. I have used opkg to install ppp, ofono, and ofono-tests however I have not been successful in finding the modem when I use the test scripts from Ofono. usb 1-1.1: GSM modem (1-port) converter now attached to ttyUSB2īus 001 Device 005: ID 12d1:1596 Huawei Technologies Co., Ltd. option 1-1.1:1.2: GSM modem (1-port) converter detected usb 1-1.1: GSM modem (1-port) converter now attached to ttyUSB1 option 1-1.1:1.1: GSM modem (1-port) converter detected usb 1-1.1: GSM modem (1-port) converter now attached to ttyUSB0 option 1-1.1:1.0: GSM modem (1-port) converter detected usbserial: USB Serial support registered for GSM modem (1-port) usbcore: registered new interface driver option usb 1-1.1: new high-speed USB device number 5 using ci_hdrc The modem is recognised on insertion as a ttyUSBx device. I first attempted this by using the Toradex Easy Installer to install the Toradex provided image (2.7.4).
My preference is to have the modem managed by Connman and Ofono I am trying to install a Huawei USB modem (MS2372h) on a Colibri iMX7D 1GB SOM and Colibri Evaluation Board (V3.2B).
