Various problems with flashing the Dongle with Softdevice using Keilhttps://devzone.nordicsemi.com/f/nordic-q-a/48085/various-problems-with-flashing-the-dongle-with-softdevice-using-keilHi, I have a few issues with flashing the dongle. I am using [ \nRF5_SDK_12.3.0_d7731ad\examples\peripheral\blinky\pca10031\s130\arm5_no_packs ] When flashing the soft device (pressed load after selecting flash_s130_nrf51_2.0.1_softdevice for theen-USTelligent Community 13Wed, 05 Jun 2019 08:10:55 GMTRE: Various problems with flashing the Dongle with Softdevice using Keilhttps://devzone.nordicsemi.com/thread/190989?ContentTypeID=1Wed, 05 Jun 2019 08:10:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:14b012c3-da5a-477c-8348-038c218f1437Kenneth<p>There should be various ways (even possible from Keil, but you may want to check the softdevice hex file is not read or write protected in some way, I have seen that may cause issue):</p> <p><a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/nrf51_getting_started.html?cp=5_1_1">https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/nrf51_getting_started.html?cp=5_1_1</a>&nbsp;</p> <p>Click on the &quot;<a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/getting_started_softdevice.html">run an example that uses the SoftDevice</a><span>.</span>&quot;</p><div style="clear:both;"></div>RE: Various problems with flashing the Dongle with Softdevice using Keilhttps://devzone.nordicsemi.com/thread/190482?ContentTypeID=1Mon, 03 Jun 2019 11:30:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f6fbc2d2-5a0b-416d-843b-9f135bf8a257horacelai<p>Hi,</p> <p>I found this thread that suggested to use nrf go studio instead. The instructions were to:</p> <ol> <li><span>Erase everything on the dongle using nrfgo studio</span></li> <li><span>Flash the softdevice using nrfgo studio. </span></li> <li><span>Flash&nbsp;the code using Keil to the dongle.</span></li> </ol> <p>Is this the only way? Is it impossible to get Keil to work for flashing the softdevice?</p> <p>Also, I suppose I only need to flash the softdevice once, correct? Now that the blinky example is working with this method, I can see that my changes to main.c is reflecting on how the led is blinking, without any reflashing of the softdevice</p><div style="clear:both;"></div>
