Powering the nRF51822 Development Kit

[Andre Lochner]

I bought the nRF511822 development Kit, not realising that it needs the nRFgo motherboard to supply power to it.So i have to make do with what I have. I am trying to power the board, I connected 3V3 to pin 1 on P2 and GND to pin 5 on P2. I can program and verify with the J-Link and the nRFgo software. When i run the blinky demo nothing happens and I can see no current draw on my supply. Is there any other pin i need to connect to 3V3 or GND ? It almost look to me like the device is stuck in reset ?

Any help will be appreciated !:)

Thanks, I really appreciate the support. This is the first time I used them so new device. I use NRFgo studio, click on nRF51 Programming under the device manager. I then program with example/arm/_build/blinky_arm.hex. I don't see a current draw while programming or erasing. The tool does tell me Erase completed. I can also do successful read once I have programmed. I haven't programmed a bootloader.

When you say you don't see any current consumption, what does that actually mean? Is it exactly 0, or is it some microamps? Did you ever try flashing a softdevice, or doing an erase all? Does that change anything? Do you see any activity on the pins that are normally LEDs (P0.08-P0.15)?

When just the CPU is running, I'd expect to see ~4 mA of consumption, and this is what you should see when flashing blinky.

Have you tried the other board that came with the kit?
