Regression: "target was not halted as expected..." - for pyocd 0.36 versions

[prosper00]

I've recently noticed some issues with 0.36 release (also the 0.36-dev) series. Reverting to an earlier version of pyocd (in this case, 0.35-dev), and everything flashes (and functions) as expected.

[the pyocd.yaml file specifies the .pack to use, I'm using the one from https://github.com/IOsetting/hk32f030m-template/tree/main/Misc]

Also see #1646

Hi,

I too have problems with 0.36:

0.36:

PS D:[...]> pyocd erase --chip -t stm32l071cbtx
0001057 I Erasing chip... [eraser]
0001181 W T bit in XPSR is invalid; the vector table may be invalid or corrupt [cortex_m]
0001209 C target was not halted as expected after calling flash algorithm routine (IPSR=3) [main]

0.35.1 (same HW, did not even unplug the DAPlink):

PS D:[...]> pip uninstall pyocd
Found existing installation: pyocd 0.36.0
Uninstalling pyocd-0.36.0:

So there definitely is an issue. I updated the pack to the current version (2.3.0?) which didn't fix the issue.
The MCU is obviously a STM32L071CBT6 (Cortex M0+)
