OpenOCD 无法打开与 STM32L4 板的连接 (STEVAL STWINCSV1)

Question

我有一块带有 STM32L4R9 芯片的 STEVAL STWINCSV1 板，通过 USB 连接到我的电脑。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 尝试打开与开发板的连接。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 插入电路板并检查 dmesg | grep usb 的输出时，这是我得到的（我多次插入电路板）：

当我运行 openocd -d -f board/stm32l4discovery.cfg 时，这里是输出（因为它有点长所以粘贴）：https://pastebin.com/biVLuf7U

有谁知道这里可能出了什么问题？

Answer 1

我想通了这个问题。首先，我使用的评估板不支持通过其 USB 端口进行 stlink，所以我不得不使用 stlink/v3 迷你外部编程器。另外，我的发行版上最新的 OpenOCD 版本不支持 stlink/v3，所以我不得不从源代码编译 OpenOCD。这解决了我的问题。
