Hi,

In my measurement of boot current with MSP-TS430RHB32Aand battery, the current consumption is over 10.0mA.
And the execute S/W is simle blinky hex code.
Off course whe measure the current ,remove Jumper2 to LED.

It seems to load current go to bypass Capacitor C9=470nF for Vcore as below document:
Figure B-17. MSP-TS430RHB32A Target Socket Module, Schematic

Is it correct measurement?
