remap section .exception

--- Quote Start ---

hi guys,

i would like to map the .exceptions section to a location in memory different to the location specified in the autogenerated linker script or exclude it at all from the elf file.

the linker flag --section-start=.exceptions=0x1100000 has been ignored by the ide.

is there any other way to move this section or an option to tell the linker to ignore it?

thanks for any help!

In the SOPC builder under "More cpu settings" you can change the exception address, which will change where the exceptions section is located. I think that&#39;ll probably change where everything else is located too though.

Also if you want to pass options to the linker you need to use the -Wl option. For instance, I have one of my projects configured to generate a map file when it builds. So in the C/C++ Build section, I have the string "-Wl,-Map -Wl,app.map" in the Linker Flags box. Maybe that&#39;s why the IDE is ignoring your --section-start option?

Finally you can use a customized linker script by going into your system library properties and choosing "Custom linker script". I think most people make a copy of the generated.x file, name it something else, and then modify it according to their needs. I&#39;m not too familiar with the syntax there, but if you search for "generated.x" or "linker" I&#39;m sure you&#39;ll find some threads with instructions on how to modify it.
