Nucleo STM32H5 debugging OpenOCD

[margce]

Hi all,

I recently got a Nucleo STM32H563ZI board to start doing development with the STM32H5x family of microcontrollers but I'm having issues trying to setup a debug session in VSCode. I've download the STM32 OpenOCD version and compiled it as it seems to have support for STM32h5x.

Has anyone successfully launched a debug session in VSCode? 

I'm using Cortex-Debug and have tried different configurations with openocd but no luck. 

Thanks!

Thanks! Will take a look at and get back to you if I need anything.

Hi Nemui,

I stumbled onto this after needing to incorporate an STM32H5 project with PlatformIO and the standard OpenOCD installation doesn't include H5 support. I've replaced the local installation with your compiled binaries (many thanks!) but am running into an issue seemingly from the OpenOCD build when trying to upload or debug:

embedded:startup.tcl:28: Error: Can't find interface/stlink.cfg
in procedure 'script' 
at file "embedded:startup.tcl", line 28
*** [upload] Error 1

I've verified that there is in fact a file at interface/stlink.cfg, but wondering if you have any tips on this.

Dear SSpen,

Can you execute OpenOCD standalone(execute OpenOCD from windows powershell)?
If executes correctly,problems may be in PlatformIO settings.

Here is my example output.

PS C:\Devz\ARM\ocd> ./openocd.exe  -s C:/Devz/ARM/OCD/tcl -f interface/stlink-dap.cfg -c "transport select dapdirect_swd" -f target/stm32h5x_flash.cfg -c "mt_flash main.elf"
