Hardware reset and halt on connect

Is there a way to connect to a device in sleep mode?
Can I issue a hardware reset, and halt the processor before trying to connect?

Currently I'm getting this error:

pyocd.core.exceptions.ProbeError: STLink error (11): Debug power error

I've had this issue before using OpenOCD
Changing the following line in the device config file resolved it.

from: reset_config srst_nogate
to:   reset_config trst_and_srst srst_nogate connect_assert_srst

When first connecting and disconnecting the stlink-utility and then running the script there are no issues.

Start by tracing the reported connection path through pyocd/core/session.py, pyocd/board/board.py, pyocd/core/coresight_target.py, pyocd/coresight/dap.py, pyocd/probe/stlink_probe.py, and pyocd/probe/stlink/stlink.py. Compare the existing reset configuration handling with the requested connect-and-reset behavior and identify relevant tests or device configuration entry points. Done should be defined as reliably connecting to the affected sleeping device while supporting hardware reset and processor halt before connection.
