I find this to be a more reliable tool when programming SoftDevices and erasing chips.</p> <p>Essentially you want to call the following.</p> <p>nrfjprog --family nrf52 --eraseall</p> <p>nrfjprog --family nrf52 --program [YOUR FILE LOCATION/SDK_HEX_FILE]</p> <p>Then you can download the application firmware as normally in Keil.</p> <p>We also have a series of tutorials here on DevZone. <a href="https://devzone.nordicsemi.com/tutorials/2/">Setting up an example project on the nRF51</a> DK and <a href="https://devzone.nordicsemi.com/tutorials/4/">Testing and using a simple BLE application</a> are good places to start.</p> <p>Let me know if anything is unclear or you experience any more issues.</p> <p>Best regards,</p> <p>Øyvind</p><div style="clear:both;"></div>
