Readwrite Sample program

Hi,

 

I'm trying to run the readwrite sample program from DSP Link 1.65, but without success.

I followed the instructions on http://processors.wiki.ti.com/index.php/Writing_DSPLink_Application_using_PROC_read_and_write_APIs i.e. I reserved the two regions READMEM and WRITEMEM.

When I try to run the program i get this:

 

./readwritegpp readwrite.out 2280652800 1024 1

I suspect a error in the memory mapping but I can't see what's wrong...

Here are the config files:

5270.configs.tar.gz

 

Does anybody have a suggestion?

 

Thanks,
