Using it without the explicit chip target works without problems. Log with -t cortex_m instead:

So this isn't super criticial but it's still kinda bothersome and maybe interesting to you that debugging with an explicit chip target from that pack fails, while the general cortex_m mode works.

Hi @maxgerhardt, thanks for reporting the issue. I think the problem is caused by the memory region definitions in the CMSIS pack. I've seen some issues in other STM32 packs, so I'll double check the L476 pack when I get a chance and report back. (I also need to make pyOCD more resilient to these kinds of issues.)
