pyocd fails to write cortex_m0 / hk32f030mf4p6 chip after upgrade to 0.36 #1646

Hi, Was trying to upgrade a controller with the following commands:

pyocd erase -c -t hk32f030mf4p6 --config ./pyocd.yaml
pyocd load ./Project/MDK5/Objects/LCM_Light_Control_IO_WS2812_New.hex -t hk32f030mf4p6 --config ./pyocd.yaml

The pack and config files above are in this repository: https://github.com/surfdado/floatwheel/tree/main/LCM

The first erase went fine, however all subsequent erase and load command were failing with the following error:

0000875 I Erasing chip... [eraser]
0001000 W T bit in XPSR is invalid; the vector table may be invalid or corrupt [cortex_m]
0001032 C target was not halted as expected after calling flash algorithm routine (IPSR=3) [__main__]

After downgrading to 0.34.3, I was able to erase and load binary file

I can confirm this issue

I'm with a similar issue. My workaround is to use 2 python environments, one with the latest (0.36.0) for some devices from ST and another one with the last version that worked with my specific device from Silabs (0.34.3).

I have the same issue with STM32L051 target on pyOCD 0.36, this condition occurs after erase operation (W T bit in XPSR is invalid; the vector table may be invalid or corrupt [cortex_m]). Target works normally after erasing flash after downgrading to version 0.35.0.
