https://devzone.nordicsemi.com/f/nordic-q-a/12558/using-pca10001-board-with-nrf51-sdk-on-mac-os-xI am interested in developing an nRF51822 application for an old PCA10001 nRF51 evaluation kit using a Mac OS X platform. I&#39;ve downloaded and installed the following tools: nRF51 SDK (nRF51_SDK_10.0.0_dc26b5e.zip) S110 BLE peripheral soft deviceen-USTelligent Community 13Wed, 16 Mar 2016 00:08:54 GMThttps://devzone.nordicsemi.com/thread/47663?ContentTypeID=1Wed, 16 Mar 2016 00:08:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7615c2d5-105a-4d1d-8f5d-9589e54d559cRK<p>Yes change the two defines for the board to BOARD_PCA10001.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/47662?ContentTypeID=1Tue, 15 Mar 2016 15:58:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:042e61dd-743c-4952-9804-236c7c702a37pozix604<p>How do I &quot;edit the makefile in there to change the board define to BOARD_PCA10001&quot; ? I see <code>CFLAGS += -DBOARD_PCA10028</code> and <code>ASMFLAGS += -DBOARD_PCA10028</code>. Change these? I also don&#39;t know what I&#39;m supposed to be looking out for in the linker script (in the Makefile?) since I&#39;m not familiar with this SDK yet. Can you elaborate?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/47661?ContentTypeID=1Tue, 15 Mar 2016 09:46:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e0bf5586-403f-402a-9098-383847d8bf8aRK<p>Copy one of board directories, eg pca10028, to pca10001, then go edit the makefile in there to change the board define to BOARD_PCA10001. You may also need to look at the linker script and ensure it matches your board.</p><div style="clear:both;"></div>
