This error message appears when the ISS has detected that your elf file does not match the system described in your ptf file. What it is attempting to do (and failing), is load data from your elf file that should go into a chunk of memory, starting at address 0x20. Check that there is a memory peripheral at that address, and that your elf file has been built for that ptf file.
