nRF51822-Development-Kit power supply and software download

[TT]

Hi, I've received the nRF51822-Development-Kit, this morning and I can't download any software to the boards.

I've install keil uvision 4.71.2.0, nRFgo Studio and the J-link driver. supply 3.3V to the board using connector P1-pins 1&3, and connector P2-pins 1&2.

I'm trying to download to the PCA1004/5 one of the examples code "Blinky project". and I'm getting error message: "Device not found".

did I miss anything? is it possible to work with nRF51822DK without the motherboard? what is the correct device for the project?

many thanks for the help!

If you take a look at the hardware files for the development kit, you can find schematics for the board. As far as I can see, everything should be working correctly if you connect pin 2 on K2 to GND and pin 2 and 3 on K1 to VCC, ~3.3 V. Pin 2 on K1 is sufficient to get the chip running, but you need to conenct pin 3 as well to make the Segger see the voltage.

When I test this, I'm able to program the chip with nRFgo Studio as usual.
