 Linux 燒錄方法 (Linux Flash eMMC Method) 

    1. 創建一個可以開機的SD Card 

     先確認SD卡在Ubuntu 系統(x86) 所認到的SD卡代號

      Command: sudo fdisk - l 

      RSB-3720 SD fdisk info 2021-10-28 113030.jpg

   2. 燒錄鏡像到SD 卡中. 

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

     RSB-3720 dd SD info 2021-10-28 113804.jpg

   3. 將flash tool 拷貝到U盤 

      RSB-3720 cp file into USB 2021-10-28 115157.jpg

'  4. '設定終端機(Set Debug Terminal) 

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. 


  5. 將可開機的SD 卡插入 SD 插槽, 並打開電源開機 

   RSB-3720 SD solt 2021-10-28 115806.jpg

6. 確認撥碼開關 為 SD 卡開機模式  

SD 卡開機: 1, 2 on 

RSB-3720 SD Card boot up 2021-10-28 132021.jpg

'eMMC 開機: '2 on

RSB-3720 eMMC boot up 2021-10-28 132058.jpg

7.打開電源,由終端機可看到開機訊息 

RSB-3720 debug message 2021-10-28 132358.jpg

8. 開機後 請再重新開機一次,系統將會重新劃分磁區大小.

9. 燒錄SD卡前, 請將U盤插入USB port  

10. 在系統確認U盤 

     RSB-3720 check usb in system 2021-10-28 132956.jpg

11. 將flash tool 燒錄鏡像,拷貝到根目錄

 RSB-3720 cp flashtool to root 2021-10-28 133320.jpg

RSB-3720 cp root check 2021-10-28 133504.jpg

12. 解壓縮 flash tool 

RSB-3720 unzip flash tool 2021-10-28 134631.jpg

13. 執行燒錄eMMC 

   Note: eMMC : /dev/mmcblk2

  RSB-3720 flash eMMC done 2021-10-28 141001.jpg

14. 移除SD卡 ,重新開機,並切換撥碼開關 

RSB-3720 eMMC boot up 2021-10-28 132058.jpg

15. 從eMMC 開機,debug 訊息
