&lt;p&gt;I solved the problem with nrfjprog (part of the nRF command line tool).&lt;/p&gt;

&lt;p&gt;Can you write the full exact error message here, or provide a screenshot of the error message?&lt;/p&gt;

&lt;p&gt;When I try to download softdevice and bootloader (nRF5_SDK_15.0.0_a53641a\examples\dfu\secure_bootloader\pca10056_ble) to 52840 (PCA10056) DK board with nRFgo studio, verification failure will occur.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: about 52840 （pca10056) program bootloader</title><link>https://devzone.nordicsemi.com/thread/214399?ContentTypeID=1</link><pubDate>Thu, 10 Oct 2019 13:36:40 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:34bfd61a-3c37-48d0-adb8-85f042d0061c</guid><dc:creator>tesc</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;I am not sure if nRFgo Studio fully supports programming the nRF52840, as the nRF52840 is a relatively new SoC. Can you use either &lt;a href="https://infocenter.nordicsemi.com/topic/ug_nrf5x_cltools/UG/cltools/nrf5x_nrfjprogexe.html"&gt;nrfjprog&lt;/a&gt; (part of &lt;a href="https://infocenter.nordicsemi.com/topic/ug_nrf5x_cltools/UG/cltools/nrf5x_command_line_tools_lpage.html"&gt;nRF Command Line Tools&lt;/a&gt;) or the &lt;a href="https://infocenter.nordicsemi.com/topic/ug_nc_programmer/UG/nrf_connect_programmer/ncp_introduction.html"&gt;nRF Connect Programmer&lt;/a&gt; application instead? nRFgo Studio has not been actively developed lately, and we recommend the tools that I just mentioned for new development.&lt;/p&gt;
&lt;p&gt;Regarding the validation failure, when exactly does it happen, and what exactly does the error look like?&lt;/p&gt;
&lt;p&gt;Regards,&lt;br /&gt;Terje&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
