1 安装JLINK驱动
在官网https://www.segger.com/downloads/jlink/ 下载.deb驱动包,本次下载的是V7.58b,直接双击安装

2 通过openocd和JLINK连接目标板

sudo openocd -f interface/jlink.cfg -f target/stm32f4x.cfg -c init -c "reset halt"
结果报错了:

Open On-Chip Debugger 0.11.0-snapshot (2021-10-12-23:33)

For bug reports, read
    http://openocd.org/doc/doxygen/bugs.html
Info : auto-selecting first available session transport "jtag". To override use 'transport select <transport>'.
Info : J-Link V9 compiled May  7 2021 16:26:12
Info : Hardware version: 9.50
Info : VTarget = 3.332 V
Info : clock speed 2000 kHz
Error: JTAG scan chain interrogation failed: all zeroes
Error: Check JTAG interface, timings, target power, etc.
Error: Trying to use configured scan chain anyway...
Error: stm32f4x.cpu: IR capture error; saw 0x00 not 0x01
Warn : Bypassing JTAG setup events due to errors
Error: Invalid ACK (0) in DAP response


根据提示,是由于默认采用JTAG连接,需要通过transport select <transport>'改变成默认使用SWD
于是打开jlink.cfg进行修改,对于本机,openocd安装在:

/usr/local/share/openocd
打开/usr/local/share/openocd/scripts/interface/jlink.cfg在其中添加如下内容:transport select swd

改后如下:

#
# SEGGER J-Link
#
# http://www.segger.com/jlink.html
#

adapter driver jlink
transport select swd

# The serial number can be used to select a specific device in case more than
# one is connected to the host.
#
# Example: Select J-Link with serial number 123456789
#
# jlink serial 123456789

再次连接后成功:

sudo openocd -f interface/jlink.cfg -f target/stm32f4x.cfg -c init -c "reset halt"
