Thank you Hung Bui, it was same problem, I edited the linker file and it worked

/* Linker script to configure memory regions. */

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

MEMORY
{
  FLASH (rx) : ORIGIN = 0x1b000, LENGTH = 0x25000
  RAM (rwx) :  ORIGIN = 0x20001fe8, LENGTH = 0x6018
    /** Location of bootloader setting in flash. */
  BOOTLOADER_SETTINGS (rw) : ORIGIN = 0x0003FC00, LENGTH = 0x1000 

}

SECTIONS
{
   /* Place the bootloader settings page in flash. */
  .bootloaderSettings(NOLOAD) :
  {

  } > BOOTLOADER_SETTINGS

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

INCLUDE "nrf5x_common.ld"

Bootloader origin is specified by BOOTLOADER_SETTINGS_ADDRESS in nrf_dfu_types.h

Hi Roger, Thanks a tonne. That might be it, but I'm unable to check the memory size in the linker file. How does one do that? Below is my linker file:

/* Linker script to configure memory regions. */

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

MEMORY { FLASH (rx) : ORIGIN = 0x1b000, LENGTH = 0x25000 RAM (rwx) : ORIGIN = 0x20001fe8, LENGTH = 0x6018 }

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

INCLUDE "nrf5x_common.ld"

Thanks a tonne!

Keil and GCC have different stack handling, are you sure your linker file has the correct memory size (RAM) for the device you are using?
