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 )
