nrf52832 custom board programming

[pdpro]

I tried some steps and falling back to support. I received my custom nRF52832 board and wanted to kickoff programming the board to meet my requirements. I used nRF52840 DK to connect DebugIn port to my custom board and started nRF connect software. I can understand that the software wanted to communicate with my target nRF52832 board, but getting response as unknown. The most probable reason for this is lack of bootloader on custom board. 

First of all, I wanted to know the steps the programming the bootloader on nRF52832 custom board. I tried to give the path from following SDk: C:\NordicSDK\nRF5_SDK_15.2.0_9412b96\components\softdevice\mbr\nrf52832\hex

However, it is not getting programmed as expected. Full log as shows below:

I am comfortable with Segger IDE for development. Please help me with the steps.

Hi,

Try to use nrfjprog with the --recover command.

[pdpro]

I tried using nrfjprog command and I can see that chip got fully erased. However, my question is how to setup environment for custom nrf52 board. I was fully comfortable working with nRF52840 and most of the sample codes in SDK are available for these boards PCA10056 & PCA10059.

As per my understanding, nRF52832 has PCA20020 but nowhere SDK having these configuration in examples. How to compile code for my custom board and use segger studio for downloading and debugging the program?

PCA20020, aka Thingy:52, has it's own SDK, found here.

As per my understanding, nRF52832 has PCA20020 but nowhere SDK having these configuration in examples. How to compile code for my custom board and use segger studio for downloading and debugging the program?

If you have custom board with nRF52832, use the pca10040 project, but modify and create your own board file. See this link.  Simply copy the existing board file (e.g. pca10040.h), rename it, and modify it after your requirements (change pin configuration, etc). Then modify boards.h to include and support your new file, e.g.

..
#elif defined(BOARD_CUSTOM)
  #include "custom_board.h"
..

Then remove BOARD_PCA10040 preprocessor symbol/define, and add your own(BOARD_CUSTOM).

Thanks, I just made changes in PCA10040 and used nRF52DK for uploading a blink program. It started working as expected.

Though, I am able to fully program my custom board using nRF52 DK, there is one unusual thing happening. nRF52 DK is also getting programmed same as my custom DK. 

For example, I run BLE_APP_BLINKY on board and then nRF Connect mobile app shows two different advertisers, one from my custom board and another from nRF DK. I don't think it is usual behavior as I program other devices such as nRF52 dongle using DK and it perfectly dumps the program in dongle only. Please let me know if I am missing something in segger setup.
