You can solder a wire to one of the output pins of the MC33269D-3.3G voltage regulator.

The 5V LDO regulator may be the culprit...you could check it by disconnecting everything else from your netduino mini and have it powered by the battery. Then you can measure the voltage on the +5V pin of your netduino to see if it is properly regulating.(by the way I don't know your level of expertise but I'll assume you have it wired correctly) Another thing you should check is if the battery is discharged<again use a voltmeter to measure it's voltage output>. Last time I checked, netduino plus is kinda power-hungry and those 9V batteries can't supply much current.

In Topic: Native programming, which tools do I need?

I'm not really experienced, but when I think about ARM this is what comes to my mind: Compiler/IDE+JTAG debugger+complex documentation/beginner unfriendly=$$$$$$ well, that's about it for "pre" arm cortex devices. If you want an easy to play development kit you should try STM32F4-Discovery. It comes with a programmer/debugger, CMSIS libraries making life easier, DSP libraries and you can use a free license IDE with it(Attolic True Studio).
