I am currently developing software of the nrf9160 and am having trouble with a firmware upgrade. The firmware data is received via UART. All of the functions work as expected but when the device reboots, the new firmware doesn't run.
int firmware_update_demo(char *URL)
{
char *demo_pointer = NULL;
const void *buf;
size_t len;
size_t firmware_update_len;
int response = 0;
uint8_t mcubuf[1000];
dfu_target_mcuboot_set_buf(mcubuf, sizeof(mcubuf));
int set_buf = dfu_target_mcuboot_init((size_t)file_size,0, NULL);
LOG_WRN("Dfu target init: %d", set_buf);
//
CODE TO COLLECT THE DATA OVER SERIAL IS HERE
//
int offset_get = dfu_target_mcuboot_offset_get(&fota_offset);
LOG_INF("Offset get: %d", offset_get);
LOG_INF("offset: %d", fota_offset);
int dfu_write = dfu_target_mcuboot_write(firmware_block, content_len);
LOG_INF("dfu write: %d", dfu_write);
int download_done = dfu_target_mcuboot_done(true);
LOG_INF("DOWNLOAD DONE: %d", download_done);
// Set back variables to default values
fota_offset = 0;
start_range = 0;
int schedule_update = dfu_target_mcuboot_schedule_update(0);
LOG_ERR("Update Scheduled: %d", schedule_update);
k_sleep(K_MSEC(10000));
sys_reboot(1);
;
return 0;
}

On Startup i am also calling:
int err = boot_write_img_confirmed();
LOG_INF("Is image confirmed: %d", err);
How do i determine if the new image ever attempted to run?
