STM32WL33 Debug prove ST-LINK(ST-LINK GDB server) not working

[ola]

Hi All,

I have just started a project with STM32WL33CC1 MCU. To get started I am trying to run and debug the example MRSUBG_Chat project.
The project builds fine but refuses to enter debugging.

I can program the WL33 using STM32CubeProgrammer and STM32_Programmer_CLI.exe version 2.18. An earlier version of the STM32_Programmer_CLI.exe
version 2.14 that I had on my laptop did not work. 

I can debug using OpenOCD option but I can not seem to debug using the ST-LINK GDB server option. Is there something that I am missing?
I noticed that the STM32CubeIDE calls the STM32CubeProgrammer_CLI.exe using the same command tool that works when ran manually. 

I noticed that if I ran STM32CubeProgrammer_CLI.exe with mode=HwRstPulse then the error I get is similar to what the STM32CubeIDE throws.

As mention earlier I can manually use STM32_Programmer_CLI.exe to connect with the following 

C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin>STM32_Programmer_CLI.exe --connect port=SWD

Hi Andrew,

I am using the NUCLEO-WL33CC1

HI Andrew,

Just for completion. Please find below.

1. [Part Number] NUCLEO-WL33CC1 
2. [Environment] Windows 11 laptop
3. [Schematics] Using ST Nucleo board.
4. [Details] STM32CubeIDE would not enter debug.
5. [Expected behavior] It should enter debug like other STM32 micros
6. [How to reproduce] Simply connect to USBC socket on PC
7. [Occurrence] The problem is constant
8. [Sanity checks] Changed cable. Confirmed boards with STM32CubeProgrammer, STM32CubeProgrammer_CLI.exe, OpenOCD

Many thanks in advance.

Regards

Hello @ola 

I'm escalating this behavior to the concerned team (under internal ticket number 199780). I will be back to you as soon as I have any updates.

For the STM32CubeProgarmmer V2.14.0, this is due to the fact that the STM32WL3 is a new product (after the release of the V2.14.0)

Best Regards.

Hi STTwo-32,

Thank you for your reply. Yes I can understand why an old tool does not support a new device that was not available when the tool was being built. This is not an issue as this was easily solved by using STM32CubeProgrammer V2.18.0.

I look forward to hearing from your team.

Hi All,

While ST sort out the bug reported in this thread. In the meanwhile as a work around we can use OpenOCD as a debugger and connect to multiple boards using the following steps outline below.

1. Select Debugger tab for Debug Configuration
2. From Debug probe using the drop down combo box select ST-LINK (ST-LINK GDB server)
3. From the Interface section check the ST-LINK S/N radio button followed by pressing the Scan button. This would populate the combo box with list of board serial number attached to your PC.
4. Identify each boards serial number and create separate configuration for the board as show below do forget to click apply to save your changes.
5. From Debug probe using the drop down combo box select ST-LINK (OpenOCD)
6. In the section OpenOCD Setup, enter into the Edit box -c "hla_serial DEADBEFE3331511234333834" Note that the -c is not in the quoted string but outside.
7. Click apply to save your configuration.
8. Happy debugging

Hello @ola 

Thank you so much for the work around you have implemented, I suggest you sold SB30 (on the back of the MB180-NoUSB-D02) board. 

PS: this should work fine will using the MB180-NoUSB-D03.

Best Regards.

Hi STTwo-32,

I can confirm that by soldering the SB30 connection located on the back of the NUCLEO-WL33CC1 causes the ST-LINK(ST-LINK GDB server) Debug probe option to work.

Many thanks one again.

Regards
