现象 CPU: STM32107VC 用JLINK 烧写程序时出现NO Cortex-m device found in JTAG chain 如图无法查找到硬件就是CPU 提示1:NO Cortex-M device found inJTAG chain.please check the JTAG cable and the connected devices 提示2:error:flash download failed-target DLL has been cancelled 原
问题是这样产生的,我在linux下安装jlink,启动JLinkExe执行,总是提示不能通过usb连接: SEGGER J-Link Commander V5.10q (Compiled Mar ::) DLL version V5.10q, compiled Mar :: Connecting to J-Link via USB...FAILED: Can not connect to J-Link via USB. 折腾好久,上segger的论坛,有人遇到和我一样的问题,也是在ubuntu下
两种 一.JTAG调试(5针), 二.SWD调试(2针), 在JTAG/SWD模式设置库函数 (在文件stm32f10x_gpio.c中): void GPIO_PinRemapConfig(uint32_t GPIO_Remap, FunctionalState NewState) setup设置 1.Debug: use j-link cortex. run to main 2.Utilities: use Debug Driver Update Target before Debuggin
Fixed J-Link 1. Erase (1) Power On (2) Jump "ERASE"(JP3) (3) Wait for 5s (4) Break "ERASE"(JP3) (5) Power Off 2. TST (1) Jump "TST"(JP1) (2) Power On (3) Wait for 10s (4) Power Off (5) Break "TST"
Test access port (TAP) JTAG defines a TAP (Test access port). The TAP is a general-purpose port that can provide access to many test support functions built into a component. It is composed as a minimum of the three input connections (TDI, TCK, TMS)
