By default, you should see something like this in your linker file:</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="lukaszadrapa_0-1705992600801.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/259553i4B192388CF3B3258/image-size/medium?v=v2&amp;px=400" role="button" title="lukaszadrapa_0-1705992600801.png" alt="lukaszadrapa_0-1705992600801.png" /></span></P> <P>All the code resources are forced to program flash like this:</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="lukaszadrapa_1-1705992646711.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/259554i4A3C497514665498/image-size/medium?v=v2&amp;px=400" role="button" title="lukaszadrapa_1-1705992646711.png" alt="lukaszadrapa_1-1705992646711.png" /></span></P> <P>Just change it to data flash which is already defined in the memory segments.</P> <P>IVT can be placed also to the data flash, so there's no problem with this:</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="lukaszadrapa_2-1705992746998.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/259556iE1B2327AF168B468/image-size/medium?v=v2&amp;px=400" role="button" title="lukaszadrapa_2-1705992746998.png" alt="lukaszadrapa_2-1705992746998.png" /></span></P> <P>And there's one more thing - data flash can be already used like this in default linker file:</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="lukaszadrapa_3-1705992790858.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/259557i5EC17E8A528B085E/image-size/medium?v=v2&amp;px=400" role="button" title="lukaszadrapa_3-1705992790858.png" alt="lukaszadrapa_3-1705992790858.png" /></span></P> <P>So, you need to update this too. Easiest way is to split the data flash to two segments. Use the first segment as program flash and use the second segment for ROM data.</P> <P>Regards,</P> <P>Lukas</P> <P>&nbsp;</P> Tue, 23 Jan 2024 06:54:57 GMT lukaszadrapa 2024-01-23T06:54:57Z https://community.nxp.com/t5/S32K/S32K3-Bootloader-customization/m-p/1792892#M30933 <P><SPAN>How to put the bootloader code in the DFlash memory</SPAN></P> Mon, 22 Jan 2024 10:05:21 GMT https://community.nxp.com/t5/S32K/S32K3-Bootloader-customization/m-p/1792892#M30933 enthuCutlet 2024-01-22T10:05:21Z https://community.nxp.com/t5/S32K/S32K3-Bootloader-customization/m-p/1793514#M30970 <P>Hi <a href="https://community.nxp.com/t5/user/viewprofilepage/user-id/225878">@enthuCutlet</a>&nbsp;</P> <P>it's just necessary to update the linker file in your project.
