I dont know but maybe (or definitely) you guys are way more advanced tha
me that's why I'm getting nothing, so to be clear I have an fpga board o
it is the virtex 4 and lots of other chips including an sram module and
flash (scan disk) and something called linear flash all this is on the SAM
board as the FPGA and what I'm trying to do is to use these modules to sav
information temporarily, so I need to save data in the sram (the on
ONboard) to be able to use later. I'm using VHDL to code my project, and m
question is; HOW can I use these resources which are on the same board.

please help the declaring big array did not work.
any tutorials or sample code is greatly appreciated

thanks a lot guys and best of regards
