Dear Wyy,
After correct the SWDIO connection, I still get the “Failed to get the CPU status…” message.
( I am trying KM0 Bootloader first…)
- shoud I power the board while using SWD ?
( USB-plug ? mmm, I had tried…) - Is the SWD interface default on ?
- Should I check the eFuse value ? Any eFuse samples by using Arduino?
- Any other advise ?
And, one more thing/clue:
1.if I connect the Vref to 3.3V on this Mini board, I’ll get the “J-Link Driver” error first…
if choosing “No” abort, the flow will go to “Failed to get CPU status…” error.
2 If I leave the Vref open, it directly goes into “Failed to get CPU status…” error.
