I tried to get access at motmdm, but no: root@devuan:/home/user# minicom -D /dev/motmdm1 minicom: cannot open /dev/motmdm1: No such file or directory root@devuan:/home/user# ls -al /dev/motmdm1 ls: cannot access '/dev/motmdm1': No such file or directory root@devuan:/home/user# dmesg | grep motmd root@devuan:/home/user# zcat /proc/config.gz | grep MDM CONFIG_MFD_MOTMDM=y CONFIG_SND_SOC_MOTMDM=y CONFIG_PHY_MAPPHONE_MDM6600=y root@devuan:/home/user# uname -a Linux devuan 4.20.0-rc7-00304-gde109fe #19 SMP Sat Dec 22 20:16:19 CET 2018 armv7l GNU/Linux root@devuan:/home/user# Let me try to enable CONFIG_GNSS_MOTMDM. N_GSM also seems enabled. Is there anything else I need to enable in .config? Scary Solstice!
