Data from FPGA to host

Hello,

I tried to post something but it doesn't appear, maybe because of an attached file.

So I tried the sdram tutorial on http://www.alteraforum.com/forum/showthread.php?t=45927

but my console tells:

Writing to 256 SDRAM locations

Error:invalid command name "get_service_paths"

Error: while executing

Error: (procedure "sdram_test" line 4)

Error: invoked from within

and I don't know what I should do.

Do you understand the error?
