Some errors occured when starting debug with Eclipse+pyOCD+JLink

0005890:INFO:gdbserver:Attempting to load argon

The traceback points to pyocd/gdbserver/gdbserver.py, pyocd/commands/commands.py, and pyocd/utility/cmdline.py. Start by tracing how Eclipse sends the remote command reset init and how reset_type is parsed, then reproduce the startup flow with Eclipse, pyOCD, and JLink. Done means the reported startup error is resolved and the relevant behavior is covered by a test.
