nRF51 does not update firmwarehttps://devzone.nordicsemi.com/f/nordic-q-a/6147/nrf51-does-not-update-firmwareHi, I have purchased a Nordic nRF51 and start to write my firmware using mbed OS compiler. As far as I can see the whole process was working perfectly. I could update the firmware, see the board led blinking and right away the new firmware was workingen-USTelligent Community 13Fri, 20 Mar 2015 12:25:09 GMTRE: nRF51 does not update firmwarehttps://devzone.nordicsemi.com/thread/21525?ContentTypeID=1Fri, 20 Mar 2015 12:25:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:28d9d65f-ade4-487d-bc4f-ebf401fa4e73raffaeu<p>So I found the answer going through mbed OS forum and I guess it can be useful for everybody. I have downloaded the soft version s110_nrf51_8.0.0 and using nRFgo studio I had to wipe out my board, install the s110 v8 and everything went back to normal</p> <p>The cause was an embed eink display which was plugged using the wrong pins which caused the board to go in error mode and not able to recover anymore</p><div style="clear:both;"></div>
