https://devzone.nordicsemi.com/f/nordic-q-a/2808/nrf24lu1-bootloader-in-nrfgo-studioHi All, I&#39;ve just been trying to program some of my USB dongles, nRF24LU1P-F16, via nRFGo Studio. They are recognised fine, and seem to be operational after programming, BUT....I get &quot;Circuit was not programmed correctly&quot; in the log messages box.en-USTelligent Community 13Sun, 06 Jul 2014 22:23:40 GMThttps://devzone.nordicsemi.com/thread/10777?ContentTypeID=1Sun, 06 Jul 2014 22:23:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dac4828a-0517-4312-950d-9db340cd9c00Simon Third<p>Hi Hakon,</p> <p>I&#39;m using 1.16.1.3119 Studio.</p> <p>I think I&#39;ve found the issue. Turns out the chips I was using where 32k parts, and selecting the 16k check box option caused the problem.</p> <p>Would you expect the same error to occur when I use the 16k parts when the program is bigger than 14k? I&#39;m at 14002 bytes currently so getting close to overwriting the bootloader.</p> <p>Also, can you get the Studio Log window to be cleared at the start of each programming cycle? It would make it clearer when programming many devices.</p> <p>BR Simon3</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/10776?ContentTypeID=1Tue, 24 Jun 2014 11:25:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1f5ca6dd-b8d5-440b-bb15-bb9140635051H&#229;kon Alseth<p>Hi Simon,</p> <ol> <li>Which version of nRFgo Studio are you using?</li> <li>Does this verification error happen every time?</li> <li>Have you tried using a different hex file to verify that the one you have is not going into the bootloaders address area?</li> </ol> <p>BR Håkon</p><div style="clear:both;"></div>
