无法在 CLion 中进行 STM32 调试

Question

我正在尝试在 CLion 中调试 STM32F446ZE 微控制器的 C++ 代码，但没有成功。

我一直在使用VsCode + CortexDebug，没有任何问题。 VsCode 中成功调试会话的示例输出：

openocd -c "gdb_port 50000" -c "tcl_port 50001" -c "telnet_port 50002" -s /repo
-f /home/user/vscode/extensions/marus25.cortex-debug-1.10.0/support/openocd-helpers.tcl
-f interface/stlink.cfg -f target/stm32f4x.cfg

所有断点都有效，响应灵敏，SVD/memview 工作良好。

现在，当我尝试使用 CLion + OpenOCD 下载并使用（据我所知）相同的配置运行时：

/usr/local/bin/openocd -c "tcl_port disabled" -c "gdb_port 3333" -c "telnet_port 4444" -s /usr/local/share/openocd/scripts -f board/stm32f4discovery.cfg -c "init;reset init;" -c "echo (((READY)))"

使用“openocd.cfg”（也尝试过 board/stm32f4discovery.cfg 和 board/st_nucleo_f4.cfg，结果相同）

source [find interface/stlink-v2.cfg]
source [find target/stm32f4x.cfg]

似乎一切都很顺利，但是...

...MCU 在系统时钟配置上立即崩溃，而在使用 VsCode 和 Cortex 调试时不会发生这种情况。

此时我怀疑gdb+openocd配置有问题，但我无法弄清楚。 我在 OpenOCD 日志中注意到的唯一区别是：

Info : auto-selecting first available session transport "hla_swd". To override use 'transport select <transport>'.
Info : The selected transport took over low-level target control. The results might differ compared to plain JTAG/SWD

对

Info : The selected transport took over low-level target control. The results might differ compared to plain JTAG/SWD
srst_only separate srst_nogate srst_open_drain connect_deassert_srst

如有任何帮助，我们将不胜感激。

奖金： 当在 CLion 中使用带有 st-util 的嵌入式 GDB 时，它可以正常工作，不会崩溃，但速度太慢，以至于无法使用。

同样的问题：我的 ctg 文件是这样的：

# 1. choose st-link/j-link/dap-link etc.##########################################
# adapter driver includes: ftdi, usb_blaster, usbprog, jlink,
# vsllink, rlink, ulink, arm-jtag-ew, hla, osbdm, opendous,
# picoprobe, cmsis-dap, xds110, st-link
adapter driver jlink
# the above line equal to the following line
# source [find interface/jlink.cfg]

# 2. select SWD port: swd, jtag
transport select swd

# 3. set adapter download speed (kHz)
adapter speed 2000

# 4. set flash size(0x100000=1048KB=1MB, 0x00080000=512kB)
# set FLASH_SIZE 0x100000
set FLASH_SIZE 0x080000

# set target type
source [find target/stm32f4x.cfg]

# connect under reset
# reset_config srst_only

运行后出现错误：
