The variable must be initialized inside a function since the FICR value is not going to be known at compile-time.

eg.

/* device_id defined globally. Will be zero-initialized by startup code */
static uint32_t m_device_id;

void my_function(void)
{
    m_device_id = NRF_FICR->DEVICEID[0]; /* Assign Device ID from FICR to m_device_id variable */
}

Hi,

Are you looking for an ID that's unique for each device? You can use the DEVICEID[] registers store in FICR for that.

Can you elaborate on what didn't work specifically?
