快速入门 (Quick Start)

系统下载 (OS Download)

  • 'Linux系统 (Linux OS)'   

Linux 燒錄方法 (Linux Flash eMMC Method)

使用Flash tool 燒錄鏡像到eMMC (Flash image into eMMC by Flash Tools) 

Step0: 檢查SD卡在Linux 環境的代號 (check SD card symbol in Linux system) 

[[File:ROM-5620fdisk 2021-09-11 145401.jpg|RTENOTITLE]]

[[File:ROM-5620fdisk SDinfo2021-09-11 145609.jpg|RTENOTITLE]]

Step1: 創造一張可開機的SD 卡 (Create a bootable SD card)

[[File:ROM-5620dd 2021-09-11 150036.jpg|RTENOTITLE]]

Step2: 將可開機的SD 卡插入底板SD卡卡槽(Plug the SD card into Carrier board 's SD card slot)

 [[File:CarrierboardSDsolt.jpg|RTENOTITLE]]

Step4: 確認開機選擇指撥開關 

           SD 卡開機模式:

           [[File:SDBootupSwitch.jpg|RTENOTITLE]]

Step3:打開電源 和 終端機 (Turn on the Power & Terminal)

   

Step4: 解壓縮flash tools 檔案,並複製到U盤中(Unzip the flash tools file , then copy to USB Disk) 

    解壓縮(Unzip the file ) 

     

 複製檔案到U盤中 (Copy the flash file to USB Disk) 

  1. 插入U盤到你的Ubuntu 電腦上 (Plug the USB Disk into you Linux PC

  2. 檢視U盤在Ubuntu 系統代號 (Check the USB Disk's symbol in Ubuntu System) 

       [[File:USBDISK info2021-09-11 170716.jpg|RTENOTITLE]]

 3. 掛載U盤在Ubuntu 系統中 

      

        

     

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
<pre>   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</pre>

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)：
