Should I try the gcc-port… many thanks in advance. Greetings Klaus ---

Don’t know if you have to uninstall your exiting version first or not.  The kickstart is limited to 32K for ARM7. ---

From the pop up window, select the linker category, followed by the Config tab. In the linker command file region of the tab, do you have the "Override default" check box checked and $PROJ\_DIR$\resource\at91SAM7X256\_NoRemap.xcl selected? If not the check the box and enter $PROJ\_DIR$\resource\at91SAM7X256\_NoRemap.xcl as the file to use. Does that fix it? ---

Try a fresh download of the FreeRTOS source code, then open the project from your new version of the ide.  You should find it builds with no warnings (hopefully 😉 ---
