Hi,

I'm sorry for the late response. I tried to recreate this problem with gcc when I found that there was a typo in the SD document. The flash origin should be 0x1C000 and not 0x2000 as stated in the documentation. This will be fixed in the next release.

linker script:

/* Linker script to configure memory regions. */

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

MEMORY
{
  FLASH (rx) : ORIGIN = 0x0001C000, LENGTH = 0x24000 
  RAM (rwx) :  ORIGIN = 0x20002800, LENGTH = 0x1800 
}


INCLUDE "gcc_nrf51_common.ld"

Hi,

does really no one have any idea.

Maybe it is because of this setting ind makefile where i flash the soft device.

echo "device nrf51822\nspeed 1000\nw4 4001e504 1\nw4 0x10001000    
$(FLASH_START_ADDRESS)\nw4 0x10001010 0xFFFF0053\nloadbin 
 $(PWD)/$(OUTPUT_DIR)/sd_s120.bin 0\nr\ng\nexit\n" > $(OUTPUT_DIR)/upload-softdevice.jlink

for what is nw4 0x10001000 $(FLASH_START_ADDRESS)\nw4 0x10001010 0xFFFF0053 good for? maybe this require a boot loader, but first i do not need any boot loader.

Best regards, Nils
