For instance: I did cmsis-dap programmer with mbed code form github. Can I do that with Keil? Just set properly IROM1 and IRAM1 values? Is something similaren-USTelligent Community 13Fri, 20 Mar 2015 10:24:04 GMThttps://devzone.nordicsemi.com/thread/111980?ContentTypeID=1Fri, 20 Mar 2015 10:24:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2fb6080b-3b91-4b76-8952-98410c6782d0Nguyen Hoan Hoang<p>I have not used Keil to flash softdevice but it should work. I tested CMSIS-DAP debugging with Keil &amp; CrossWork, both work fine. Crossworks can also be used to flash softdevice. That I have test.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/111979?ContentTypeID=1Fri, 20 Mar 2015 09:54:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:66cda66e-831d-4b23-9696-4ef099f4e54cwesthouse<p>Thanks, your program will be very helpful for me. But I&#39;m curious, will it work also with Keil when I set properly IROM1 and IRAM1 values from data sheets and set to CMSIS-DAP debugger?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/111978?ContentTypeID=1Fri, 20 Mar 2015 09:36:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7763b11d-ffd0-4fda-84b7-308156988a2dNguyen Hoan Hoang<p>You can use IDAPnRFProg with IDAP-Link. <a href="http://embeddedsoftdev.blogspot.ca/p/idap-link.html">IDAP-Link is a full cmsis-dap debug jtag</a>. See this blog <a href="http://embeddedsoftdev.blogspot.ca/p/idap-link.html">http://embeddedsoftdev.blogspot.ca/p/idap-link.html</a></p> <p>Other option is to use OpenOCD or pyOCD program command but it&#39;s a lot slower</p> <pre><code>openocd -f interface/cmsis-dap.cfg -f target/nrf51.cfg -c &quot;program s110.hex verify&quot; </code></pre><div style="clear:both;"></div>
