快速入门 (Quick Start)

系统下载 (OS Download)

 

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)

 

 

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

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)

Step4: 確認開機選擇指撥開關

SD 卡開機模式:

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

 

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

Step 5: Yocto 系統會自動掛載 U盤 在(run/media/sda1下)

RTENOTITLE

並拷貝 5720A1AIM30LIVA0271_iMX8M_2G_flash_tool.tgz 到根目錄 (copy the file into Yocto system) 

     Commnd :  cp -a  5720A1AIM30LIVA0271_iMX8M_2G_flash_tool.tgz  /

在Yocto 系統中解壓縮(Unzip the file in Yocto system on ROM-5720)

Step 6. 燒錄eMMC 鏡像 (flash image into eMMC flash by flash tool file) 

  command : ./mksd-linux.sh /dev/mmcblk0

 

Step 7 . 結束燒錄後, 請改變撥碼開關至 1 on , 其他 off (eMMC開機模式) (Finish the flash process, please chanage the switch (SW1) to 1 on , others off )

 

移除SD卡, 拔除電源 ,改變撥碼開關 (unplug the SD card , turn off power , change the SW1 switch to eMMC mode (1 on , others off)

eMMC mode : 1 on , others off

Step 8. 重新上電開機 ( Turn on the power , then check the Debug message)

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

RTENOTITLE

 

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.
