I’m trying to connect LTE module (Telit LN940A9) to Xavier using USB. I received the customized kernel patch (qmi_wwan.c, option.c) and a rule file. try to build the kernel following this step (https://developer.ridgerun.com/wiki/index.php?title=Xavier/JetPack_4.1/Compiling_Code/Kernel) and add the rule file to /etc/udev/rules.d.
After this procedure, qmi_wwan port and sirial port should be recognized but I cannot confirm them.
These ports are shown when I tried to connect this module to Linux PC (ubuntu generic).
What kind of things do you think could be the cause?
