https://devzone.nordicsemi.com/f/nordic-q-a/2229/nrf51822-hangs-while-running-with-s110-softdevice-and-s110-hrs-appI have a nRF51822 Evaluation kit I am trying to get up and running. My kit has the older QFAACA part. I followed the steps to setup eclipse and GCC and i am successfully compiling. I adapted the GCC makefile and eclipse project to the PCA10001 boarden-USTelligent Community 13Mon, 18 Aug 2014 22:25:14 GMThttps://devzone.nordicsemi.com/thread/9389?ContentTypeID=1Mon, 18 Aug 2014 22:25:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ece81dc0-4508-405f-8aa9-4d7ba01135d2Stephen<p>I experienced a similar issue. The solution was to ensure I had the correct version of the soft device installed. I was using v6.0.0 and when I switched to v7.0.0 like magic, everything started working.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/9388?ContentTypeID=1Wed, 07 May 2014 00:31:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b439ab56-119c-4106-80b2-871f8bae25b6Chris Lovett<p>You should have the source for bond_manager_init located in the SDK ~\Nordic\nrf51822\Source\ble\ble_bondmngr.c, so in stepping through that where does it hang exactly ?</p> <p>Some things to try:</p> <ul> <li>try &quot;erase all&quot; flash memory, then re-download the softdevice and your app.</li> <li>try setting m_bondmngr_config.bonds_delete to true</li> <li>the only soft device call the bond manager init makes is flash_pages_erase which calls sd_flash_page_erase.</li> <li>make sure your app is downloading to Region 1, usually 0x14000. If your &quot;main&quot; function is lower than this then you probably clobbered the soft device.</li> <li>lastly make sure the SDK you compiled against matches the soft device you are using.</li> </ul><div style="clear:both;"></div>
