OpenOCD无法打开与STM32L4开发板的连接STEVAL STWINCSV1

问题描述

我有一个STEVAL STWINCSV1板，其中STM32L4R9芯片通过USB连接到我的计算机。我正在尝试使用OpenOCD刷新新图像。我正在使用命令openocd -d -f board/stm32l4discovery.cfg尝试打开与主板的连接。这是cfg文件的内容

# Explicitly for the STM32L476 discovery board:
# http://www.st.com/web/en/catalog/tools/PF261635
# but perfectly functional for any other STM32L4 board connected via
# an stlink-v2-1 interface.
# This is for STM32L4 boards that are connected via stlink-v2-1.
 
source [find interface/stlink.cfg]
 
transport select hla_swd
 
source [find target/stm32l4x.cfg]
 
reset_config srst_only

当我通过USB插入开发板并检查dmesg | grep usb的输出时，我得到的是（我多次插入开发板）：

当我运行openocd -d -f board/stm32l4discovery.cfg时，输出如下（因为它有点长，所以进行了粘贴）：https://pastebin.com/biVLuf7U

有人知道这里可能出什么问题吗？

解决方法

我发现了问题。首先，我使用的评估板不支持通过usb端口进行stlink，因此我不得不使用stlink / v3 mini外部编程器。另外，我发行版中最新的OpenOCD版本不支持stlink / v3，因此我必须从源代码编译OpenOCD。这解决了我的问题。
