F28035 Solar Power Inverter Developer's kit Problem

Hi,

I'm on the F28035 Solar Power Inverter Developer's kit, Now I'm trying to create a new CCS v4 project and copy related file to my new folder, and remove unnecessary files(such as files for F2833x, F2802x etc. and **example** etc.)

Now errors ocurr after building, like below, could anyone give me some suggestions?

Regards,

Felix

    What you have here is a problem during linking.  Basically the linker is attempting to assign an object ".text" of size 0xd46 (3398 words) to the range RAML0L1 which is of size 0xc00 (3072 words) and is spitting an error because 3398 > 3072 and it doesnt fit.  The same is happening for "ramfuncs".

    This problem is easy to fix using some advanced memory management - splitting the objects into smaller objects and assigning them to different areas of RAM.  As long as there is enough spare RAM everything should be fine.  Are you able to copy your linker command file (.cmd) for your project into a reply and I will hopefully provide some methods of getting rid of your problems with this information.

     

    Thanks,
