系统下载 (OS Download)
- Linux系统 (Linux OS)
OS Support List (based on Ubutu 18.04)
Linux 燒錄方法 (Linux Flash eMMC Method)
Debug 串口調試 (Debug port Setting)
以 Tera Term 为例介绍如何使用串口调试功能
Baud Rate波特率：115200 Data 数据位：8 Parity 奇偶校验：无 Stop 停止位：1 Flow Control流控：无
Tera Term Tool
Check the Sriel port in Device Manager (查看PC端的串口号)：
if you can not identify the Serial device , please check your serial driver.
Debug port connection (串口連接)
Log into Terminal Tool (进入串口调试终端)：
Linux系统的基本使用(Linux System Basic Operating Method)
UUU 使用方法(USB Connection (OTG port))
乙太網路使用方法(Ethernent Testing Method)
Command : ifconfig
Command: Ping - I eth1 8.8.8.8 or Ping - I eth0 8.8.8.8
WiFi使用方法(WIFI Testing Method)
串口使用方法(Serial Port Operating Method)
RS-232 Test
CN15上(SER0/UART3): /dev/ttymxc2
CN15 下(SER2/UART1): /dev/ttymxc0
COM 3 (A53 debug/SER3/UART2): /dev/ttymxc1

SW7 Setting (SW7設置)
MODE1 MODE0
0 0 LOOPBACK
0 1 RS232
1 0 RS485
1 1 RS422
Loopback test (eg. ttymxc0)
Connect loopback test tool
- stty ‐F /dev/ttymxc0 115200
# stty ‐F /dev/ttymxc0 ‐echo
# cat /dev/ttymxc0 &
# echo test > /dev/ttymxc0
蓝牙使用方法(BlueTooth Operating Method)
Command : $ hciconfig hci0 up $ bluetoothctl $ discoverable on $ pairable on $ scan on [NEW] FC:18:3C:8D:75:F4 myphone $ scan off $ pair FC:18:3C:8D:75:F4 $ connect FC:18:3C:8D:75:F4

SSH Remote Log into Device
- SSH远程登录,以putty选择putty.exe(或者使用Xshell、SecureCRT等类似软件)
- 需要设置远程设备的IP、通讯端口(默认22)、通讯方式，登录后验证用户名密码
通用方法(General Method)
查看CPU温度(Check CPU Temperature)
查看CPU频率(Check CPU Frequency)
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
>> 900000
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
>> 1200000
查看内存容量(Check Memory Capacity)
busybox free -m
查看存储容量(Check Storage Capacity)
busybox df -h
