Putting together a first reference design with nRF52832

[SteveQuinn]

Hi,

Forgive what may seem like a stupid question, but...

I would like to create a first reference PCB design using an nRF52832 for an IoT project I am working on.

I would like to programme it via a Segger Jlink EDU from the Segger Embedded studio (if this is possible).

I've done a reasonable degree of searching on the Nordic site and have not been able to find any circuit diagrams highlighting how to connect up a jtag device the nRF52832.

Could someone point me to a URL on the Nordic site where I could locate this information, perhaps an App Note?

Regards

SQ

As I say apologies in advance if this sounds like a stupid question.

There is a simple schematic here that you can look at here sourceforge.net/.../.  It uses a certified module but the SWD is the same. The file is IBK-BLYST-NANO_QuickStart.pdf.  Look for the connector P2.  That is how you connect the SWD to a standard ARM Coresight 10 pins

Hi Nguyen,

Thank you for your reply.

I did take a look and compared the schematic in the QuickStart guide (connector P2) for your product and compared against the segger jlink Interface Description but was unable to make a direct pin for pin correlation. 

I was thinking more along lines of official Nordic Semiconductor literature similar to what Microchip do for their ICD which is a very good and clear document.

My hesitation is as I mention above I want to commit my design to PCB and have it manufactured and therefore need to refer to manufacturers formal literature as opposed to a third part design, albeit a very good one I'm sure as it looks like a very nice product.

Do you think I should approach Nordic direct to get answers to;

• Application note for programming connections for Segger Jlink EDU and nRF52832
• Can the Segger Jlink EDU from the Segger Embedded studio

Best Regards

Steve

The ARM standard connectors https://developer.arm.com/documentation/dui0499/d/ARM-DSTREAM-Target-Interface-Connections/CoreSight-10

The require pins are :  SWDCLK, SWDIO, RESET, GND, VCC. just connect those to yours connector.
