快速入门 (Quick Start)

系统下载 (OS Download)

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)

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

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)

Step4: 確認開機選擇指撥開關

SD 卡開機模式:

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

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

Step 5: Yocto 系統會自動掛載 U盤 在 /run/media/sda1 下

並拷貝 5720A1AIM30LIVA0271_iMX8M_2G_flash_tool.tgz 到根目錄 (copy the file into Yocto system)

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)

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

./mksd-linux.sh /dev/mmcblk0

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 change the switch (SW1) to 1 on, others off)

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)

eMMC mode: 1 on, others off

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

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 Serial 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.

Debug port connection (串口連接)

Log into Terminal Tool (进入串口调试终端):
