But I am facing hardfault issue in Clock driver. From my observation the hardfault is not ocurring because of insufficient memory, there is sufficient memory available in sram. I would like to know that is there any limitations in acessing the sram memory.</P><P>Note:</P><P>1)I have created a project with dual core(CM0,CM1) enabled.&nbsp;&nbsp;</P><P>2)I am attaching the memory usage of existing project created and a new folder integrated project.&nbsp;</P><P>3)Just adding 700 extra byte size is causing a hardfault.<span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Existing project memory usage" style="width: 765px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/367087i3EB236E9601BB259/image-size/large?v=v2&amp;px=999" role="button" title="image.png" alt="Existing project memory usage" /><span class="lia-inline-image-caption" onclick="event.preventDefault();">Existing project memory usage</span></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Memory usage after integration of new folder" style="width: 999px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/367090i362EF1549D4E2A06/image-size/large?v=v2&amp;px=999" role="button" title="image (1).png" alt="Memory usage after integration of new folder" /><span class="lia-inline-image-caption" onclick="event.preventDefault();">Memory usage after integration of new folder</span></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="image (1).png" style="width: 999px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/367089i03A25ED017B47D5D/image-size/large?v=v2&amp;px=999" role="button" title="image (1).png" alt="image (1).png" /><span class="lia-inline-image-caption" onclick="event.preventDefault();">image (1).png</span></span></P><P>&nbsp;</P><P>Regards,</P><P>Varshni</P><DIV class="">&nbsp;</DIV><DIV class="">&nbsp;</DIV><P>&nbsp;</P> Tue, 25 Nov 2025 06:52:15 GMT https://community.nxp.com/t5/S32K/MEMORY-ASSIGNING-ISSUE/m-p/2248085#M54789 Varshini_ext 2025-11-25T06:52:15Z https://community.nxp.com/t5/S32K/MEMORY-ASSIGNING-ISSUE/m-p/2248359#M54804 <P>Hi&nbsp;<a href="https://community.nxp.com/t5/user/viewprofilepage/user-id/257286">@Varshini_ext</a>,</P> <P>There are many possible root causes.</P> <P>Try find more information about the fault exception.</P> <P><A href="https://community.nxp.com/t5/S32K-Knowledge-Base/Example-S32K312-HARDFAULT-Handling-Interrupt-DS3-5-RTD300/ta-p/1806259" target="_blank">https://community.nxp.com/t5/S32K-Knowledge-Base/Example-S32K312-HARDFAULT-Handling-Interrupt-DS3-5-RTD300/ta-p/1806259</A></P> <P><A href="https://community.nxp.com/t5/S32K-Knowledge-Base/How-To-Debug-A-Fault-Exception-On-ARM-Cortex-M-V7M-MCU-S32K3XX/ta-p/1595570" target="_blank">https://community.nxp.com/t5/S32K-Knowledge-Base/How-To-Debug-A-Fault-Exception-On-ARM-Cortex-M-V7M-MCU-S32K3XX/ta-p/1595570</A></P> <P><A href="https://community.nxp.com/t5/S32K-Knowledge-Base/Fault-handling-on-S32K14x/ta-p/1114447" target="_blank">https://community.nxp.com/t5/S32K-Knowledge-Base/Fault-handling-on-S32K14x/ta-p/1114447</A></P> <P>&nbsp;</P> <P>What kind of fault exception is it?</P> <P>What is the PC address of the fault instruction?</P> <P>&nbsp;</P> <P>Thank you,</P> <P>BR, Daniel</P> Tue, 25 Nov 2025 11:42:24 GMT https://community.nxp.com/t5/S32K/MEMORY-ASSIGNING-ISSUE/m-p/2248359#M54804 danielmartynek 2025-11-25T11:42:24Z
