Applications
The following applications have been installed:
wpa_supplicant
chromium
minicom
iperf3
Performance Mode
Configurate CPU GPU NPU and DDR
Configurate CPU GPU NPU and DDR to performance mode at the same time:
# echo performance | tee $(find /sys/ -name *governor) #
Configurate CPU only
# echo performance | tee $(find /sys/devices/system/cpu/cpufreq/policy* -name *governor) #
U-Disk
U-Disk will be mounted at /run/media/sda1 automatically./run/media/sda1 is most common condition, it may be /run/media/sdb1 /run/media/sdc1.
Plug out U-Disk, see which one is disappeared, and then to plug in U-Disk again.

AT Port
How to find AT Port:
# dmesg | grep ttyUSB [ 5.574612] usb 3-1: cp210x converter now attached to ttyUSB0 [ 5.586590] usb 3-1: cp210x converter now attached to ttyUSB1 [ 5.598584] usb 3-1: cp210x converter now attached to ttyUSB2 [ 5.610583] usb 3-1: cp210x converter now attached to ttyUSB3 [ 18.535820] usb 2-1: GSM modem (1-port) converter now attached to ttyUSB4 [ 18.542643] usb 2-1: GSM modem (1-port) converter now attached to ttyUSB5 [ 18.548504] usb 2-1: GSM modem (1-port) converter now attached to ttyUSB6 [ 18.553115] usb 2-1: GSM modem (1-port) converter now attached to ttyUSB7
ttyUSB4 to ttyUSB7 are ports for GSM modem.
And ttyUSB6 (the second port counted backwords) is the port for AT command.
Firmware Version
How to get Firmware Version for EC20.
Take ttyUSB6 as AT port, change it according your DUT.
# stty -F /dev/ttyUSB6 9600 # cat /dev/ttyUSB6 & # echo -e "ATI\r\n" > /dev/ttyUSB6 Quectel EC20F Revision: EC20CEFRGR06A04M4G OK
EC20CEFRGR06A04M4G is firmware verion.
