Nios ii de2

Hi,

I am a beginner and NOSII Quartus I operate Altera DE2, I wanted to use the SD card (memory card from my Altera DE2) board for a project.

after sending the architecture of the example that comes with the CD named DE2_SD_Card_Audio, I encountered a problem while sending the executable file (. sof), and here is the error message that is displayed "launching XXX2013Nios II Hardware configuration has Encountered a problem. Elf downloading process failed". Another alternative display shows that there is a problem between address "Verifying failed 0X6000000 address and 0X600FFFF Between", these addresses correspond to memory addresses 2 (RAM U2).

and this is the complete downloading messages:

"Using cable "USB-Blaster [USB-0]", device 1, instance 0x00

Reading System ID at address 0x09405178:

As i notice there is a Warning, is this warning mean that there is a problem in my Hardware archiecture vs software definitions, or there is something that i can't undrestand.

NB: the file. Sof that comes with the example works fine, but when I compile the example and brings ALTERA gives me another SOF File. Sof gives the problem mentioned before.

Please help friends.
