See <a href="https://devzone.nordicsemi.com/question/16176/s310-and-iar-i-jet-loadrun/">this</a> and <a href="https://devzone.nordicsemi.com/question/33022/iar-i-jet-debugging-wont-run/">this</a> thread. In general, any SWD compliant debugger should work. However, we cannot guarantee that it will work, you will have to verify this by yourself. Check out chapter 16 - Debug and trace in <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52/dita/nrf52/chips/nrf52832_ps.html?cp=2_2_0">nRF52832 product specification</a> or chapter 11 - Debugger Interface in <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf51/dita/nrf51/pdflinks/ref_manual.html?cp=3_2">nRF51 reference manual</a>. You might also get som support from the developer of the debugger.</p> <p>nRFgo Studio <a href="https://devzone.nordicsemi.com/question/33421/nrfgo-and-iar-i-jet/">will only work with SEGGER debuggers</a>, i.e., the I-Jet will not work.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
