https://devzone.nordicsemi.com/f/nordic-q-a/83032/how-to-configure-keil-uvision-for-using-sdk17-1-0-on-a-pca10028-boardI have a legacy board and i would like to use it with sdk 17.1.0. But sdk getting started page did not have detailed explaination. I have done #define BOARD_PCA10028 to the main function of an example and changed the target device as nrf51422_xxCAen-USTelligent Community 13Wed, 22 Dec 2021 11:17:34 GMThttps://devzone.nordicsemi.com/thread/344772?ContentTypeID=1Wed, 22 Dec 2021 11:17:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8a8e5864-5402-4b4e-927b-101c169acdbdMehmet Nuri<p>I downloaded sdk v12.3 and using it with pca10028 now.

Is there a specific reason you&#39;d like to use SDK v17.1?</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
