So, despite getting the right pack - it still doesn't work?
Internal ref; IOTPART-9002.
STLINKv3 is being used, firmware has been updated to latest one I'm aware of. details.txt says;
Version: 0221
Build: Aug 23 2019 16:25:00
Publicly more known version is V3J5M2 for STLINK-V3 boards (available via the STSW-007).
Contributor guide
First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start by reproducing the failure with pyocd list and pyocd flash on the NUCLEO-H743ZI2, then read the traceback locations in pyocd/core/session.py and pyocd/core/coresight_target.py. Done means the reported board can be flashed without the STLink "No device connected" errors or the "No cores were discovered" failure.
