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)

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

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)：
