I have Python 3.7.4 , pyOCD 0.26 and I see the same thing.

Could it be something related to the dual-core?

RcColes commented 4 years ago

I can confirm that I have also had this issue on the Musca s1, and that it works correctly after a downgrade to pyocd 0.25.0

maclobdell commented 4 years ago

@flit can you investigate or recommend the right person to investigate? Looks like there is a problem reported on multiple targets on release 0.26.0.

bohdan-tymkiv commented 3 years ago

@marcuschangarm @Quincy-Zh @maclobdell Is this issue still relevant? I've tested with different PSoC6 flavors and I can not reproduce it with latest pyOCD master.

marcuschangarm commented 3 years ago

@bohdan-tymkiv I haven't used the PSOC in awhile. Let's close it if you can't reproduce it.
