https://devzone.nordicsemi.com/f/nordic-q-a/9855/nrf52-s212-softdeviceHello, We are unable to get the softdevice to work on nrf52 DK(PCA10040) . It ends up at app_error_handler each time. We have followed previous recommendations about LFCLK (turning it ON before the SD is enabled) and making sure FPUnit is enabled.en-USTelligent Community 13Wed, 28 Oct 2015 10:12:16 GMThttps://devzone.nordicsemi.com/thread/36576?ContentTypeID=1Wed, 28 Oct 2015 10:12:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5b817b83-37ae-48fd-887e-e0d36230ae2cagf<p>Unfortunately both version of S212 are restricted to use with nRF52832 IC rev Engineering A (see release note). On PCA10040 you have Engineering B. You can use PCA10036 which have installed Engineering A.</p><div style="clear:both;"></div>
