Which USB to power the FRDM-MCXA153 when using external MCU Link Debug Probe?

Hello, I am new to NXP microcontrollers and the MCUxpresso IDE. I have purchased the FRDM-MCXA153 and also the MCU-Link Debug Probe. I want to use the external debug probe because that is what I will use on my custom printed circuit board. I have gotten the Blinky LED example code working and with using the external debug port J18 with the MCU-Link Debug Probe.

My question is which USB connector on the FRDM board should I use to power the board J18 or J8 while I an using the external debugger?

Thank you

Hi @joe1652

I recommend using J8 as the power supply input.

Thank you.
