https://devzone.nordicsemi.com/f/nordic-q-a/16684/flash-error-in-eclipseHello guys, I followed this guide to set up the software on my macbook. The blinky example can be successfully built, but cannot be flashed to the nRF52 DK. Then I tried on Windows, it works. Here are the result in OS X and Windows.

The problem is that Eclipse doesn&#39;t the path of the command line tool. So I need to add the PATH variable in project properties or in the Eclipse preference, as shown in the pictures.</p> <p><img src="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/Screen-Shot-2016_2D00_10_2D00_29-at-15.53.55.png" alt="image description" /> <img src="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/Screen-Shot-2016_2D00_10_2D00_29-at-15.54.36.png" alt="image description" /></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/63838?ContentTypeID=1Thu, 06 Oct 2016 13:30:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:313554a1-5207-45b1-a522-c73a4c3f5f0fTong Yu<p>Thanks you. I added the full path of nrfjprog into the makefile, then it works. But I still don&#39;t know why it doesn&#39;t recognize nrfjprog, everything works pretty good in the Terminal.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/63837?ContentTypeID=1Tue, 27 Sep 2016 23:19:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:24a49a75-89e3-437f-b3a0-f6d87db33bd2Nguyen Hoan Hoang<p>Well, then it is not Eclipse issue but the makefile issue. You can check the makefile to see what wrong with it. Running a commande line in OSX requires a &#39;./&#39;</p> <p>You can also have a look at <a href="http://embeddedsoftdev.blogspot.ca/p/ehal-nrf51.html">this blog</a> for alternative way to work with OSX.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/63836?ContentTypeID=1Tue, 27 Sep 2016 16:33:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fbee6c62-235d-4699-9d09-c7b6240dd3ccTong Yu<p>Yes, I installed the Segger JLInk software, and it works fine in terminal, only not in Eclipse.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/63835?ContentTypeID=1Tue, 27 Sep 2016 12:32:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c674c498-b519-4598-b20c-5962adda407bNguyen Hoan Hoang<p>Have you installed the Segger JLink software ? It is also required. The error message said that it could not file the nrfjprog. Is your path correct. Have you tried to run the program in the terminal ?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/63834?ContentTypeID=1Tue, 27 Sep 2016 09:58:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:61523933-6539-45db-be59-591d4666cbf3Tong Yu<p>Thanks for the reply. I already had the command line tools. In OS X, I think I only need to unzip it and add nrfjprog folder to the PATH variable, right? I already done that before I post my question. So, any other way to solve that?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/63833?ContentTypeID=1Tue, 27 Sep 2016 00:01:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e7610eb1-ee4e-4326-b76c-3b8135e5ef52Nguyen Hoan Hoang<p>You need to download and install the command line tools from Nordic here <a href="https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF52832">www.nordicsemi.com/.../nRF52832</a></p><div style="clear:both;"></div>
