I set up PATH to run nrfjprog fromen-USTelligent Community 13Mon, 06 Feb 2017 09:29:41 GMThttps://devzone.nordicsemi.com/thread/75605?ContentTypeID=1Mon, 06 Feb 2017 09:29:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ad5a11fe-f170-4e2b-92ae-a649fcd9cb80Summit<p>Hello Jorgen, No when SEGGER software was installed on my Macbook air, it was automatically installed under /Applications/SEGGER Embedded Studio 3.10i.app/ folder and the libjlinkarm.dylib was located under /Applications/SEGGER Embedded Studio 3.10i.app/bin. After getting your comments, I created /Applications/SEGGER/JLink/ folder and copied libjlinkarm.dylib to /Applications/SEGGER/JLink/ folder and it works now.</p> <p>Thank you very much for information about the default location.</p> <ul> <li>Summit</li> </ul><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/75604?ContentTypeID=1Mon, 06 Feb 2017 08:40:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7eec3300-d868-4f56-bdb2-76350590a195J&#248;rgen Holmefjord<p>Did you install the Segger driver in the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.tools/dita/tools/nrf5x_command_line_tools/nrf5x_installation.html?cp=5_0_1">default location</a>?</p> <blockquote> <p>When installing on Mac OS X or Linux, the SEGGER software must be installed in its default location, or the shared library must be placed so that dlopen() can find it.
