The compiler (+linker) a free to use any space that is defined in the memory configuration.</P> Sun, 27 Jun 2021 10:51:52 GMT converse 2021-06-27T10:51:52Z https://community.nxp.com/t5/LPC-Microcontrollers/IAP-memory-management/m-p/1298653#M45662 <P>Hi there</P><P>I am actually using the IAP functionality to save some variables into the flash. Do I need to reserve the page I use in the Memory configuration editor, or is the compiler reserving this space during build?</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="huegi_0-1624705671981.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/148079iE192944E737B95B0/image-size/medium?v=v2&amp;px=400" role="button" title="huegi_0-1624705671981.png" alt="huegi_0-1624705671981.png" /></span></P><P>I just wonder if this is necessary and could lead to unexpected errors.
