https://devzone.nordicsemi.com/f/nordic-q-a/120260/clarification-on-ipc-radio-sysbuild-optionsI&#39;m currently working on a matter application on a custom board in NCS 2.9.0. In the documentation for the ipc_radio net core image the README at nrf/applications/ipc_radio suggests enabling SB_CONFIG_NETCORE_IPC_RADIO on production and SB_CONFIG_NRF_DEFAULT_IPC_RADIOen-USTelligent Community 13Fri, 28 Mar 2025 18:20:24 GMThttps://devzone.nordicsemi.com/thread/529605?ContentTypeID=1Fri, 28 Mar 2025 18:20:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:12386058-a358-4aa1-bfcb-4921e2fbcae5timl2415<p>I haven&#39;t seen a difference when switching between the two although its strange that the documentation suggests that one is used for &quot;production&quot;. Your explanation makes sense though, thanks!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/529569?ContentTypeID=1Fri, 28 Mar 2025 14:27:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:29a2d7d6-c8c2-4fcf-ac46-dde2aad6779aHung Bui<p>Hi Timothy,&nbsp;<br /> I don&#39;t think there is a big different between&nbsp;<span>SB_CONFIG_NRF_DEFAULT_IPC_RADIO&nbsp;and&nbsp;SB_CONFIG_NETCORE_IPC_RADIO. We reserve&nbsp;SB_CONFIG_NRF_DEFAULT_IPC_RADIO for our sample and application most likely for the ability to change configuration for bulk of the samples. As far as I can see in the code I don&#39;t see the&nbsp;SB_CONFIG_NRF_DEFAULT_IPC_RADIO&nbsp; makes any difference compare to&nbsp;SB_CONFIG_NETCORE_IPC_RADIO.&nbsp;<br />Do you find anything change when you use&nbsp;SB_CONFIG_NRF_DEFAULT_IPC_RADIO&nbsp;compare to&nbsp;SB_CONFIG_NETCORE_IPC_RADIO&nbsp; ?</span></p><div style="clear:both;"></div>
