https://devzone.nordicsemi.com/f/nordic-q-a/24930/very-basic-blinky-demo-code-can-not-hit-mainI have tried blinky demo project (without BLE) in MDK5, the code can not run into main(). Why ? What happens ? I am using MDK5 to debug the code.en-USTelligent Community 13Tue, 05 Sep 2017 23:05:53 GMThttps://devzone.nordicsemi.com/thread/98164?ContentTypeID=1Tue, 05 Sep 2017 23:05:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:834b5ab9-273e-45dd-90d7-2f6deb4321c6allankliu<p>Sorry, guys. It is my fault.</p> <p>Last night is Chinese ZhongYuan Festival, so called Chinese ghost festival. And I hit two faults.</p> <h2>Wrong Path</h2> <p>The demo demands softdevice.</p> <p><strong>c:\nRF51_SDK_12.3.0\examples\peripheral\blinky\pca10028\s130\arm5_no_packs\blinky_pca10028_s130.uvprojx</strong></p> <p>The baremetal should not include s130 in the path. I should use another blank demo instead.</p> <p>c:\nRF51_SDK_12.3.0\examples\peripheral\blinky\pca10028\blank\arm5_no_packs\blinky_pca10028.uvprojx</p> <h2>Wrong Silkscreen</h2> <p>The new module I bought came along with a converter, which was designed for nRF52832, instead of nRF51822, therefore, I measured the wrong pins. Actually I meansured all of the GPIOs, then I realized it.</p> <p>So, I am not careful enough. All my fault.</p> <p>However, story didn&#39;t end. I will open another thread anyway. It is closed.</p><div style="clear:both;"></div>
