Debugging the Lora-STM32WL-devkit: Open On-Chip Debugger failed

[Volker]

Two Remarks:

1. Launching the debugger fails with a probability of about 50%.

2. OpenOCD.exe which came with STM32CubeIDE 1.10.0 does not work:

I tried using the openOCD.exe which comes with STM32CubeIDE 1.10.0. This version just issues a message and does nothing:

I believe the support for STM32wlx chips was added in OpenOCD 1.11.0, so it is expected to have problems with OpenOCD 1.10.0.
