 Linux 燒錄方法 (Linux Flash eMMC Method) 

    1. 創建一個可以開機的SD Card (Create a bootable SD card )  

     先確認SD卡在Ubuntu 系統(x86) 所認到的SD卡代號 ( Check the SD card symbol in Ubuntu System (x86)

      Command: sudo fdisk - l 

      

   2. 燒錄鏡像到SD 卡中. (Flash Image into SD card) 

        Command : sudo dd if=3720A1AIM30LIVA0333_iMX8MP_6G_2021-10-05.img of=/dev/sdf bs=1M conv=fsync 

     

   3. 將flash tool 拷貝到U盤  (Cpye the eMMC flash tool into USB Disk ) 

      

4. 設定終端機(Set Debug Terminal) 

Debug 串口調試 (Debug port Setting)

以 Tera Term  為例介绍如何使用串口調試功能 ( Tera Term is kind of terminal tool , we need to set  the parameter (Baud Rate , Data, Parity, Stop, Flow Control )  into "Tera Term  terminal tool " )  

   波特率(Baud Rate)：115200
   數據位(Data)：8
   奇偶校驗(Parity)：无 (none)
   停止位(Stop)：1
   流控(Flow Control)：无 (none) 

Tera Term Tool 

Check the Sriel port in Device Manager (查看PC端的串口號)：

if you can not identify the Serial device , please check your serial driver. 

 

5. 將可開機的SD 卡插入 SD 插槽, 並打開電源開機     (Plug into the SD card into SD Card Slot , then turn on the power) 

   

6. 確認撥碼開關 為 SD 卡開機模式  (Check the Switch)

SD 卡開機: 1, 2 on  (Set the SD card boot up mode ,  1 on  2 on ) 

'eMMC 開機: '2 on ( Set the eMMC boot up mode , 2 on , others off) 

7.打開電源,由終端機可看到開機訊息  (Turn on the power , you will see the debug message from Terminal tool ) 

8. 開機後 請再重新開機一次,系統將會重新劃分磁區大小. (If you can not not copy the eMMC flash tool into root file system , please reboot the device , because , the system will the reconfigure the partition )

9. 燒錄eMMC前, 請將U盤插入USB port   (Please pulg the USB Disk into USB port before flash eMMC)

10. 在系統確認U盤 (Check the USB disk in the Yocto System (Device side) ) 

     

11. 將flash tool 燒錄鏡像,拷貝到根目錄 (Copy the flash tool into root file system) 

 

12. 解壓縮 flash tool  (Unzip the flash tool ) 

13. 執行燒錄eMMC  (Exeucte the eMMC flash script )

   Note: eMMC : /dev/mmcblk2

  

14. 移除SD卡 ,重新開機,並切換撥碼開關 　（Remove the SD card , Change the Switch to eMMC mode , then reboot the system) 

15. 從eMMC 開機,debug 訊息  (You will see the debug message when you boot up from eMMC flash )
