Thanks! That solved the issue.

It's most likely your RAM settings. xxAA has 16K of RAM instead of 32K that the xxAC variant on the Devkit has. Try to use the following configuration in your *emProject file:

      linker_section_placement_macros="FLASH_PH_START=0x0;FLASH_PH_SIZE=0x80000;RAM_PH_START=0x20000000;RAM_PH_SIZE=0x4000;FLASH_START=0x1b000;FLASH_SIZE=0x25000;RAM_START=0x20001fe8;RAM_SIZE=0x2018"
      linker_section_placements_segments="FLASH RX 0x0 0x40000;RAM RWX 0x20000000 0x4000"

Thanks! Your example was very helpful for me also. It can be opened in SES v4.12 and works properly with nrf51 devkit.

But now I need to port it to the custom board (based on nrf51822 QFAAH1). I tried to do expected adjustments (changing target, setting BOARD_CUSTOM macro and providing custom_board.h), but without any luck - in all cases it fails with "Stopped by vector catch" even before entering main(). Any ideas what I could be missing/how can I debug the problem further? I have tried to set up breakpoints in error handlers - non of them is getting hit.

Hello,

I've backported the ble_app_hrs ses project from SDK 15.2.0 to SDK 12.3.0 which you may serve as starting point, see attached. Please note that it has not been thoroughly, it can be errors in the configuration that I've overlooked.

A short summary of what I did:

First I copied the example from SDK 15 to SDK 12, then opened the SES project file in a text editor and updated the include paths, source list, preprocessor defines and linker settings according to the project makefile and linker file found in the hrs example in sdk 12
Imported the new MDK directory, sdk_config tool, and the RTT files from sdk 15, see readme.txt in zip file.

Attachment:

devzone.nordicsemi.com/.../nRF5_5F00_SDK_5F00_12.3.0_5F00_SES_5F00_51_5F00_example.zip

Note: SDK has been stripped of dependencies that weren't needed to build this particular example Thus, the SES project directory and SDK 15 imports should be copied into a fresh SDK 12.3.0 copy so that you have a complete SDK to develop with.
