But he has it plugged into the NFC on the Sparkfun. Move it down to where it says "C" and "D" on the back of the board and you'll have the wiring correct.

My bad, I added the wrong linker script. Sorry for that and I have corrected my answer.

Hi,

Sorry for the delay in replying and thanks so much for taking the time. I have changed the linker script for exactly as is in the example you outlined. My debugger is no longer stopping on the first line of my application. It does when using the original linker script. Any ideas what might cause this ?

I am using Eclipse as an IDE and debugger.

Thanks.

You can just use the same Memory configuration as the linker script for the gcc toolchain in our SDK, ble_ant_app_hrm_gcc_nrf52.ld. You'll find it in \examples\multiprotocol\ble_ant_app_hrm\pca10040\s332\armgcc. You may also have to add the pwr_mgmt_data section if you're using that in your modified example.

   /* Linker script to configure memory regions. */

SEARCH_DIR(.)
GROUP(-lgcc -lc -lnosys)

MEMORY
{
  FLASH (rx) : ORIGIN = 0x27000, LENGTH = 0x59000
  RAM (rwx) :  ORIGIN = 0x20003800, LENGTH = 0xc800
}

SECTIONS
{
  .fs_data :
  {
    PROVIDE(__start_fs_data = .);
    KEEP(*(.fs_data))
    PROVIDE(__stop_fs_data = .);
  } > RAM
} INSERT AFTER .data;

INCLUDE "nrf5x_common.ld"
