Problem of ML605 DDR3 Usage

Hi, I'm a newbie of FPGA user. So please forgive me if anyting seems rather stupid.

When I am running the petalinux demo of the ML605 board, I use "ftpget" command to transfer some picture data to the board, maybe into the DDR3 memory. However I can not get the knowledge of the address of these data, which may be used later. is there any methods I can figure out the address of the data?

 

Thanks

Best regards

There would not be an "address" for the data, the PetaLinux kernel would store it on the file system.

Thanks, So if I want to use the data in the petalinux fie system through directly reading  from the DDR3 memory, How Can I achieve this?

Your question is a bit unusual.  Your are running an OS on top of MicroBlaze in your system.  The environment that you are using in this case is a pure software environment. 

 

How exactly were you planning on accesing the "DDR3 Memory"?

Thanks!

Actually What I'm trying to do is firstly to transfer some data from PC to ML605 DDR3 Memory, which is completed via Ethernet Cable and "ftpget" command running on Petalinux OS, secondly to read the data in DDR3 memory using RTL Implementation and do some processing to the data.

So this is how the problem comes.

 

If this is not a good way to accomplish the two tasks ,could you please give me some suggestions?

Thanks!
