Im using nRF52832 Development Kit , I need to know the 'TARGETID', of the board ??

[Nivas Bathirappan]

I'm trying to implement Serial Wire Debug to read some Data from Nordic from other Controller. Initially Need to read some registers in DP & AP Nordic. For that I need to know Target ID of the Chip. I have refereed the "nRF52832 Development Kit v1.1.x User Guide", still I cant able to find the target ID. Can you please provide me how to identify the Target ID of the Chip??

That sounds like a rather OTT approach!

Can't you just make a simple comms link over standard interface like UART, SPI, I2C ... ?

My indentation is to get Target ID of the Nordic  nRF52832 , Whatever may be the Communication .Target ID remains same correct??

You mean, "intention" ?

My point is that a simple comms link over standard interface like UART, SPI, I2C would not require the Target ID.

But, if you use a J-Link, doesn't it report the Target ID ?

Hi Awneil,

I need to read some data from Nordic(TARGET) from other Controller(HOST). As a initial step I am trying to read Target ID of Nordic from my Micro controller using SWD(FYI ,My Requirement is to use only SWD). So only I'm not using any other communication like UART,I2C,SPI. Even any documentation regarding SWD please share the same.

This is a very weird approach!

SWD, as the name suggests,  is usually only used for programming and debugging - not for application comms!

That'll be why it's not so well documented - because it's only something that people actually developing debuggers would need to know.

If you have a requirement to use SWD, then surely a thorough understanding of it is a pre-requisite?!

It is a standard ARM interface & protocol - go to the ARM site for details.

You might find the CMSIS-DAP code and/or documentation useful ...
