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:

Method 1:

# mmcli -m 0 | grep ttyUSB
           |                   ports: cdc-wdm0 (qmi), ttyUSB4 (qcdm), ttyUSB5 (gps),
           |                          ttyUSB6 (at), ttyUSB7 (at), wwan0 (net)

ttyUSB6 and ttyUSB7 are for the ports for AT command.

Method 2:

# 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
