Hi,
I am trying to connect to an NXP MKV31F512 with a J-Link Pro using the power supply feature of the J-Link.
This is with a custom board.
When using an external power supply to power the board (so the MCU gets its power from a DCDC converter), I can connect with the J-Link just fine (with power off).
Connecting fails with Commander, J-Flash and Ozone. From Ozone, I received a log file, which I attached. I hope I removed all the sensitive information like serial numbers from it.
Any idea why I cannot connect to the MCU when the J-Link powers the board but I can if the CDCD converter supplies the voltage?
Cheers
