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) 

RTENOTITLE

 

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

RTENOTITLE

 

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)

RTENOTITLE

 

Step4: 確認開機選擇指撥開關 

           SD 卡開機模式:

RTENOTITLE

 

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

   RTENOTITLE

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

    RTENOTITLE

 

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)  

  RTENOTITLE

RTENOTITLE

 

      

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

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

 RTENOTITLE

RTENOTITLE

 

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 ) 

RTENOTITLE

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 

  RTENOTITLE

 

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