System Workbench for STM32

Hi Dulan,
Thanks for your pointers. I attempted your proposal to copy and rename the .svd file.
It was not successful. I tried both making copies in their native location and also in my project directory; I tried matching the CHIPNAME and creating its prefixes, but no luck.
BTW, I'm working on an STM32F401CCU, using GDB remote debugging.
In the end this worked:
I briefly launched the the native "AC6 STM32 Debugging" configuration.
It failed because my debugger is remote, but it populated the IO registers immediately.
Then I went back to my GDB remote debugging.

Frustrating...
