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) [Use Ubuntu 18.04 to create SD card ]
解壓縮檔案(Unzip the files)
mkdir ti-sdk-XXX(XXX represents numbers, e.g. ti-sdk-001)
Command : phill@riscserver-Default-string:/home/RISC_BSP_Home/EPC-R3220/R3220A1AIM20LIV20012_am335x_2021-07-29$ mkdir ti-sdk-001
Unzip file to ti-sdk-001
Command : tar -xJf processor-sdk-linux-image-am335xepcr3220a1-20210729031957.tar.xz -C ti-sdk-001
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)
$ cd ti-sdk-XXX/bin
$ sudo ./create-sdcard.sh
Select SD card:
Select number of partitions:
Select Pre-built System image:
Select tisdk-rootfs-image-XXX.tar.xz(XXX represents machine name, e.g. am335xepcr3220a1):
If you need to transfer whole system to on-board flash, please press y followed by Enter.
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)
Step3: 確認開機選擇指撥開關(Check the SW1 switch)
SD 卡開機模式(SD card boot mode):
1--off 2---off
Step3:打開電源 和 終端機 (Turn on the Power & Terminal)
Step4: 利用mk-eMMC-boot.sh 安裝eMMC 鏡像(Flash image to eMMC Flash by mk-eMMC-boot.sh )
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 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.
Debug port connection (串口連接)
Log into Terminal Tool (进入串口调试终端):
Linux系统的基本使用(Linux System Basic Operating Method)
乙太網路使用方法(Ethernent Testing Method)
Command : ifconfig
Command: Ping - I eth1 8.8.8.8 or Ping - I eth0 8.8.8.8
WiFi使用方法(WIFI Testing Method)
M.2 Mrvl. WIFI/BT Test
EPC-R3220 supports MarverllSD8897 wifi/bt modules throught M.2.
4G使用方法(4G Testing Method)
GPIO使用方法(GPIO Operating Method)
串口使用方法(Serial Port Operating Method)
RS-232 Test
蓝牙使用方法(BlueTooth Operating Method)
Command : $ hciconfig hci0 up $ bluetoothctl $ discoverable on $ pairable on $ scan on [NEW] FC:18:3C:8D:75:F4 myphone $ scan off $ pair FC:18:3C:8D:75:F4 $ connect FC:18:3C:8D:75:F4
遠程訪問及文件傳輸(Remote Access and File Transimmion)
查看主板IP位址 ( Chech IP Address ):
Command : ifconfig
Windows下SSH访问及文件传输
SSH Remote Log into Device
- SSH远程登录,以putty选择putty.exe(或者使用Xshell、SecureCRT等类似软件)
- 需要设置远程设备的IP、通讯端口(默认22)、通讯方式,登录后验证用户名密码
Account is “root” , no password.
RS-485 測試方式 (RS-485 testing method)
Test tool script :
Uart change mode
