CCS/TMS320C6678: how to close ECC in the evm6678l.gel

Part Number:TMS320C6678

Tool/software: Code Composer Studio

Hi,

when  I  use CCS to connect to my custom,I use  C:\ti\ccsv5\ccs_base\emulation\boards\evmc6678l\gel\evm6678l.gel as my  custom board 's .gel file.

But it seems that the gel file is not match to my board. The console output:

DDR3 memory test ...Failed.

6678evm  use  5 SDRAM and use ECC.my board use 4 SDRAM  and doesnot use ECC.

I try  to delete code about ECC in the evm6678l.gel,but I didnot find it .

How do I dubug "GEL Output: DDR3 memory test... Failed"?
