Flashign on a custom PCB board

[pltv]

Hello folks

I have a custom PCB board with the attached layout diagram. I also have our firmware that was flashed on to the Nordic beacon kit and tested. I would like to flash the same on to the custom PCB board with attached drawing. Any help would be useful

@prasanna: Please upload your schematic. To be able to program the nRF51822 you to connect 4 pins to the programmer :

• GND

• SWDIO

• SWDCLK

• VDD (as reference, you still need to provide power to the board)

@hungbui i have attached the schematic diagram i got in my post. Do we need more than this?

@prasanna: Maybe there could be something wrong with the file. What I am seeing here is just 2 pages, one page with the PCB layout of the top side, and another with the PCB layout of the bottom side. What I need is the schematic.

With just the PCB layout it's not enough to know how the pins are connected.

I hav the following not from the manufacturer on the pins on the board

1. G: Ground;
2. V: Vcc, 3.0V;
3. D: Data;
4. C: CLK;

Will this be of any help in further guiding us on how to connect this board to the DK?

@prasanna: I can't say for sure if it works because I don't have the schematic. But you can try to connect the SWD programmer to your board as follow: The left is the pin on the board, the right is the pin on the programmer.

G -> GND

V -> VDD (you should provide 3.3V to this pin as well, or just put the battery in.)

D -> SWDIO

C -> SWDCLK.
