Is ARM (SWD) debugging for SAMC currently working in AS7, using a PICKit4 debugger?
Currently, it's recognizing that the PICKit is connected, but is timing out trying to do anything.
It's entirely possible that this particular board simply doesn't work, but ... shouldn't I be able to "read target voltage" without the target chip actually running? (this times out too.)
(This using the "tools/Device Programming" panel.)
I have: PICKit HW Vers 3, Firmware Version 0.0e, and Atmel Studio 7 (Version: 7.0.1931 - )
