1.      解压st-link_v2_usb driver.zip文件. 2.       运行解压后的st-link_v2_usbdriver.exe文件,安装STLINK V2驱动程序.安装路径尽量保持默认路径. 3.       安装完成后,可以在“开始”菜单中查看到STLINK V2相关选项.如图所示: 2013-7-2 10:15 上传 下载附件 (43.27 KB)   4.       将STLINK通过USB接口连入电脑. 5.       右击“我的电脑”选择“属性”打开“

Dapper Miser In late 2013, I created a functional implementation of CMSIS-DAP that runs in a low cost ~$1 PIC16F1454 microcontroller. My interest was seeing it deployed as a CMSIS-DAP debugger *integrated* into a low-cost hobbyist/educational ARM dev

JTAG是JOINT TEST ACTION GROUP的简称,JTAG的两个标准IEEE 1149.1(2001)和IEEE 1149.7(2009). JTAG中主要包含两部分内容:TAP(TEST ACCESS PORT)和BOUNDARY-SCAN ARCHITECTURE. 边界扫描的基本思想是:在靠近芯片输入输出引脚处,增加一个移位寄存器单元,称为边界扫描寄存器(Boundary-Scan Register cell) 在芯片处在debug模式下时,这些边界扫描寄存器可以将芯片和外围

ARM JTAG 调试原理 JTAG的接口是一种特殊的4/5个接脚接口连到芯片上 ,所以在电路版上的很多芯片可以将他们的JTAG接脚 通过Daisy Chain的方式连在一起,并且Probe只需连接到一个“JTAG端口”就可以访问一块印刷电路板上的所有IC. 这些连接引脚是: TDI(测试数据输入) TDO(测试数据输出) TCK(测试时钟) TMS(测试模式选择) TRST(测试复位)可选. 因为只有一条数据线,通信协议有必要像其他串行设备接口,如SPI一样为串列传输. 时钟由TCK引脚输入.

家里的计算机安装了WIN10,出于够用且安装文件小,想安装QuartusII9.1,按M$风格,驱动绝对是安不上的.正好是双系统ubuntu14.04 64位.安装过程不太顺利,记录下来,当作已经不灵光的大脑的备份. 按正常步骤安装好,并打好补丁SP1和SP2,基本顺利,这里注意的是,有的安装脚本中声明的SHELL是CSHELL,运行时有命令找不到,将声明中的CSH改为TCSH再安装即可. 接下来就是老大难的JTAG的USB BLASTER不能识别的问题. 由于ubuntu并不在官方支持的系统中
