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---on
SPL開機模式(SPL boot mode: boot from SD, MMC...)
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
