Step4: 解壓縮flash tools 檔案,並複製到U盤中(Unzip the flash tools file , then copy to USB Disk)
1. 插入U盤到你的Ubuntu 電腦上 (Plug the USB Disk into you Linux PC
2. 檢視U盤在Ubuntu 系統代號 (Check the USB Disk's symbol in Ubuntu System)
3. 掛載U盤在Ubuntu 系統中 (Mount the USB Disk's in Ubuntu System)
4. 複製檔案到U盤(Copy the file to USB disk)
5. 將U盤連接到ROM-5721系統, 進入flash tool下的mk_inand資料夾, 執行指令./mksd-linux.sh /dev/mmcblk2燒錄image到eMMC (Connect USB Disk to ROM-5721 system, browser to mk_inand folder and execute flash shell script "./mksd-linux.sh /dev/mmcblk2"
6. 切換開機switch 1:on 2,3,4,5,6:off來設定成從eMMC開機(Change boot switch to "1:on 2,3,4,5,6:off" to boot from eMMC. Reboot system).
