Clarification needed for Syslink FAQs

Hello
I have already posted a question about that here:

http://e2e.ti.com/support/embedded/bios/f/355/t/271771.aspx

I'm trying to solve the problem indicated in the Syslink FAQ as "Ipc_control(STARTCALLBACK) timeouts on TI81XX device when only the VPSS-M3 is used" where it is indicated to modify a .cfg file with some new lines.

What I cannot understand is:

1. what file should be edited?
2. how this modification affects compilation of syslink.ko? I found two files with the GateDualCore variable (named RingIO_ti81xx_vpssm3.cfg and Notify_ti81xx_vpssm3.cfg), I modified both as described in the FAQ but nothing changed. Even introducing a syntax error does nothing, so I assume they are not read at compiling time
   
3. do I need to run some compilation tools (like xdctools) in order to get new compiling options before running make? or should I use Code Composer studio?

I am able to recompile the syslink.ko module as described in http://processors.wiki.ti.com/index.php/SysLink_Install_Guide, but as already mentioned the problem persists.

Thanks a lot, do not understand how to use the tools starts being annoying...
