Was this ever resolved ?

If you have a LED connected to a GPIO or a spare GPIO (for example 21) to check on a scope or a multimeter, right after main() do the following:

main(){
  nrf_gpio_cfg_output(21);
  nrf_delay_ms(1000);
  nrf_gpio_pin_toggle(21);
  nrf_delay_ms(1000);
  nrf_gpio_pin_toggle(21);
  nrf_delay_ms(1000);
  nrf_gpio_pin_toggle(21);

This way you'll know if the processor boots properly. Otherwise also its good to have some sort of BSP for getting at least the serial output for debugging.

Just remove bsp all together

@EarthLord,

well my custom board with 16k , its bsp is not based on pca10028. it's pca10024 , i am running the example application that is under pca10028 , but this don't matter since am focusing in the advertising of the application not the bsp part , even though they are different boards.

Can you give some other details of your setup?

Its based on this module www.tindie.com/.../ It has a 16 MHz crystal and no lfclk crystal. The RAM is 16 kB and flash is 256 kB. Irrespective of the crystals, blinks a LED or send a serial message the first thing in main() to see if its working.

@EarthLord ,

just to confirm you are using also a customboard 16k and 256 flash ? and are you using any external crystal or internal .. ?

Strange, it works here. Not sure where the problem is then. Here's the linker file that I use.

/* Linker script to configure memory regions. */

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

MEMORY
{
  FLASH (rx) : ORIGIN = 0x1b000, LENGTH = 0x25000
  RAM (rwx) :  ORIGIN = 0x20002080, LENGTH = 0x1f80
}

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

INCLUDE "gcc_nrf51_common.ld"

From the datasheet you can see that RAM starts from 0x20000000. The linker file says that the RAM for the application starts from 0x20002080. Since the total size of RAM is 32 kB for xxAC, 0x2080 + 0x5f80 is 0x8000, which is 32 kB. So just change the RAM length to 0x1f80 to show that the total length is 16 kB (0x4000).
