Did you follow the reference guide (development module) schematics? It would be easier to answer your question if you posted your schematics and serial output.

I think pinout should be right. I get access via terminal and flashed successfully a new image over serial. After enable wifi and add "option antenna external" at etc/config/wireless the board always reboot. Maybe for using external antenna i missing something.
Heres the schematic: Power: PIN 49 GND, PIN 50 3V3 input Serial: PIN 43 UART RX, PIN 44 UART TX USB: PIN 20 USB+, PIN 21 USB- U.FL: external Antenna
Thanks again for attention Cheers

Thanks Peter, always the same problem didn´t thought about it. But this should be the solution. I use a cheap converter and powered the board with. I will give another try Cheers
