LoRa-STM32WL-DevKit flashing with openocd fails

[opr]

I could compile the demo with my settings but uploading the .elf always fails with:

Am I missing something? I tried it under OSX and Windows with openocd 0.12 and 0.11

Seems like openocd issue. Either the script or the  core are problematic. Make sure to test with the latest OpenOCD version.

Maybe try an older oocd, too, as they sometimes make major changes which are ... er ... not quite right first try.

I tried it on a different machine (Apple M2) and it worked with the same version.

Thank you!
