Hi Nelson, generally, from what I've seen, people usually retarget printf over UART, or use Segger RTT for logging. However, regarding the fact that its hanging, my guess is that somewhere in your project its linking to retarget.c. For instance, in my IAR project, under the nRF_Libraries group, retarget.c is linked. If I remove that file, navigate to General Options-->Library Configuration you should see an option for semihosting. If you want printf to log through IAR IO console, click Semihosted for stdout/stderr. You should now be able to see your stdout over the View-->Terminal IO window.

Let me know how you make out!
