Other Parts Discussed in Thread: MSP-EXP430FR2433
Currently I am using msp430fr2433 launchpad development kit(MSP-EXP430FR2433).
I checked 5v by connecting USB port of eZ-FET Debug Probe.
And Led102(on Demo board) glowed yellow color.
But, 3.3v is not checked anywhere on the board.
(I think... Supply eZ-FET USB Power and this power rail to 3.3 V for eZ-FET operation.)
In addition, I used the blink led example provided on the Ti homepage. And tool is iar7.2for msp430.
The IAR tool looks like board is debugging.(Attach picture)
