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: 解壓縮flash tools 檔案,並複製到U盤中(Unzip the flash tools file , then copy to USB Disk)
解壓縮(Unzip the file )
複製檔案到U盤中 (Copy the flash file 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
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
