https://devzone.nordicsemi.com/f/nordic-q-a/86404/nrf52810-gazell-implementation-with-keilHi, We currently have a Gazell project that runs on nRF52832 . We have difficulties changing the project target to the nRF52810 . From the SDK17.0.2, example: &quot;gzll_ack_payload_device_pca10040&quot;, just setting the target to nRF52810 , we get these errorsen-USTelligent Community 13Wed, 30 Mar 2022 12:23:56 GMThttps://devzone.nordicsemi.com/thread/360803?ContentTypeID=1Wed, 30 Mar 2022 12:23:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b3bf2c22-e717-4757-ad35-0e827ca3ffaeJ&#248;rgen Holmefjord<p>Hi,</p> <p>nRF52810 does not have the Floating Point Unit in the Cortex M4 CPU like the nRF52832 has. You need to use a Gazell library that is built for soft-float CPU.</p> <p>I can&#39;t find any library for the nRF52810 in the ARM directory of the Gazell library, but there is a GCC version available, which can also be used with Segger Embedded Studio (components\proprietary_rf\gzll\gcc\gzll_nrf52810_gcc.a). If you are able to port your project to one of these toolchains, you can use this library.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/360688?ContentTypeID=1Wed, 30 Mar 2022 08:38:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:503820f5-6fa1-4011-918d-a7483d50f29bMarcel<p>I already followed this guide:</p> <p><a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.0.0%2Fnrf52810_user_guide.html&amp;cp=4_0_1_5_0&amp;anchor=ug_52810_intro">Transferring the project to nRF52810 hardware</a></p><div style="clear:both;"></div>
