  • Installing OpenOCD on Ubuntu
  • Communicating with FT2232H

1. ubuntu 系统 + 安装openocd
2. OpenOCD User’s Guide

注： 本次实验中使用的系统为ubuntu 20.04

• ubuntu 20.04 安装 openocd version 0.10.0 (偷懒式安装) , 最新版本为version 0.11

$ sudo apt-get install openocd

• 查看openocd安装版本以及安装路径

• 连接FT2232H适配器,输入lsusb看到 ****Ltd FT2232C/D/H ****

$ lsusb 
Bus 001 Device 009: ID 0403:6010 Future Technology Devices International, Ltd FT2232C/D/H Dual UART/FIFO IC

• 或连接FT2232H适配器,输入dmesg

$ dmesg
......

注： OpenOCD v0.11.0 与 OpenOCD v0.10.0由些许命令不一样会报错！！！！！！

标准冒烟测试——点灯：通过OpenOCD的配置文件点亮，FT2232H硬件板上的led灯。

在ubuntu终端输入，openocd -f openocd.cfg，即可点亮两颗LED(原理图见FT2232H入门)。
