Secure DFU SDK15.3 errorhttps://devzone.nordicsemi.com/f/nordic-q-a/48569/secure-dfu-sdk15-3-errorHi! I try to compile secure DFU from examples SDK15.3 for nrf52810 (pca10040e_ble). I added old files from DFU SDK15.0 in to my new project. Also added file micro_ecc_lib_nrf52.lib compiled before for SDK15.0 where it works fine.

Should be recompile library again. Now it works.</p><div style="clear:both;"></div>RE: Secure DFU SDK15.3 errorhttps://devzone.nordicsemi.com/thread/192970?ContentTypeID=1Fri, 14 Jun 2019 14:44:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:19678e88-59b4-405b-b49b-f77b1118320aMikhail<p>Hi!</p> <p>It is good idea to recompile&nbsp;<span>microecc&nbsp;in the new SDK. I&#39;ll try it compile. I&#39;ll write later.</span></p><div style="clear:both;"></div>RE: Secure DFU SDK15.3 errorhttps://devzone.nordicsemi.com/thread/192916?ContentTypeID=1Fri, 14 Jun 2019 11:51:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:81910757-a85f-43af-90a5-b664194fc397tesc<p>Hi,</p> <p>What old files did you add to the new project? There are some changes between the SDK versions, see the <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.3.0%2Findex.html">release notes</a> for details. You may have to do some updates. If you start a new project I recommend not mixing SDK versions, even of the same major version. At the time of writing the latest nRF5 SDK version is 15.3.0.</p> <p>Can you try compiling microecc in nRF5 SDK v15.3.0 instead of copying in the files from v15.0.0?</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
