Hello,
I'm experiencing problems using my XDS200 debugger with the F280045 on a custom board, connected via a Blackhawk isolation adapter. Basically I am experiencing the exact same behavior reported in the thread. Main difference is I'm using an XDS200 debugger instead of XDS110, and my target is different.
Here is a screenshot of my target config:
Here is the schematic showing the connections from the JTAG port to the MCU:
When I test the connection without the isolation, everything passes. But when I try with the isolation, I get the 'SC_ERR_PATH_MEASURE' error:
I've tried decreasing the JTAG clock frequency, but it doesn't help. If I turn it way down (like below 500kHz) I get this error instead:
I've tried this with two different debugger/isolator combos, same results. I've had no issues using the same debugger/isolator when debugging other boards using the F28379D, so I don't think the debugger/isolator is at fault here. But my application will require isolation in the near future, no way around it.
Please advise
