Hi,

1. if i use a powersupply with micro usb on the wifi-dipcortex it does not work. it powered up only if i connect the USB cable to my pc.

2. if i use external power on pin 32 (+5V) und pin 31 (GND) the module also does not powered on. if i connect external power on this pins i have 3.3 V on pin p11. so i think the regulator works.

any ideas?

Hi,

If you can measure 3.3v on the 3.3v pin when you apply 5v the regulator is working and so should the processor.

I would eliminate the software, use a simply blinky application to just flash the led to show the micro is running.

The USB vbus is the 5v net so there should be no electrical difference

Grazy. After removing the lib USBDevice it works.
