Debug Port連接 (Ddbug Port Connection)

1. Connect debug cable to EPC-R3430 debug port

2. Connect the other side of debug cable to USB-to-RS232 cable then connect to your PC

Debug Port設定 (Debug Port Settings)

EPC-R3430 can communicate with a host server by using serial cables. Common serial communication programs such as HyperTerminal, Tera Term or Putty can be used in this case. The example below describes the serial terminal setup using HyperTerminal on a Windows host: 1. Connect EPC-R3430 with your PC by using a serial cable

2. Open HyperTerminal on your Windows PC and select the settings as shown below

3. After the boot loader is programmed on Micro SD card, insert power adapter connector to DC jack on EPC-R3430 to power up the board. The boot loader prompt is displayed on the terminal screen. HyperTerminal Settings for Terminal Setup

Linux 燒錄方法 (Linux Flash eMMC Method)

1. 確認SD 在Ubuntu 電腦中的代號

2. 先將鏡像燒錄到SD Card 中( Create a bootable SD card )

3.設定終端機(Set Debug Terminal)

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
&nbsp;  Stop 停止位：1
   Flow Control流控：无

Tera Term Tool

Check the Sriel 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.

4. 將SD card 插入機器

5. 檢查撥碼開關 ( 1 ON , 2 OFF)

6. 接上Debug Cable

7. 打開電源

8. 由終端機進入系統

9. 燒錄鏡像到 eMMC flash

將3430A1AIM20LIV90146_DualQuad_flash_tool.tgz 複製到U盤中,插入機器的USB Port

在系統中 ,確認USB中燒錄資料

在根目錄下 ,解壓縮

在mk_Inand 資料夾中執行 ./mksd-linux.sh

10. 移除SD 卡,從eMMC 開機.

Linux系统的基本使用(Linux System Basic Operating Method)

載入預設值由uboot 設定(Load Default Setting in Uboot )

1. 開機時在五秒內按下空白鍵 ,進入Uboot

2. Command :
