Yes, Kiel v5.12. This still isn't working for me though and I don't seem to have an ability to really swap out compilers. Thank you for your help anyways.

I recently had to look into a simple way of converting the device's built in serial number to a decimal ascii character array. You may find sprintf() in stdio.h to work well enough for your purposes, just provide it a large enough buffer and make sure to use the correct format parameter for your application. For example, below is what I used to convert the unsigned 64 bit hex nordic serial number to a decimal string:

#include <stdio.h>
#include <stdint.h>
#include <nrf.h>
#include "nrf_soc.h"
...
int serial_number_string_length;
uint64_t const * const serial_number = (uint64_t const *) &NRF_FICR->DEVICEID[0];
static char serial_number_string[21]; // Max decimal character length is 20 digits (result of 2^64)
serial_number_string_length = sprintf(serial_number_string, "%llu", *serial_number);

You are using Keil I presume. Try newlib-nano. I think it should be avail in the version 5.1x. I have seen some time ago. I am currently using Eclipse with GCC.

In Options for Target, I can see that I'm using MicroLIB. Not sure what exactly is the latest new library that you're referring to.

Compiled with gcc 4.9

#include <stdlib.h>
        
char buf[10];
itoa(10, buf, 10);

Can you provide a code snippet? Including <stdlib.h> doesn't seem to give me an itoa. itoa declared implicitly.

It is already part of the standard C lib. It's in the newlib that comes with the compiler.
