 I can not understand it.Maybe about settings_load()? 
 The main function in my code as follow: 
 int main(void) int主要(空白)

{

int err; int犯错;

uint32_t blink_status = 0;

struct dm_init_param init_param; struct dm_init_param; struct dm_init_param;

printk("1202 Start
"); printk(“1202年开始\ n”); printk(“1202年开始\ n”);

err = dk_leds_init(); 错误 = dk_leds_init（）; 错误 = dk_leds_init（）;

if (err) {

printk("LEDs init failed (err %d)
", err); printk(" led init failed (err %d)
"， err); printk(" led init failed (err %d)
"， err);

return 0; 返回0; 返回0;

}

err = peer_init();

int main(void)
{
	int err;
	uint32_t blink_status = 0;
	struct dm_init_param init_param;

	printk("1202 Start

	err = dk_leds_init();

	init_param.cb = &dm_cb;

	err = dm_init(&init_param);

 return 0;
	}
