How to transfer data from pc to sdram?

Hi,

What program can I use to transfer data from my PC to the SDRAM or FLASH memory on the board? I am using DE0.

For example I want to transfer the bit stream encoding an image file onto the SDRAM for later processing.

Please let me know if the question is unclear.

    So, someone told me I can use control panel but I would like to know how to do it without the magic control panel.

    So, using the de0 control panel, I am trying to write some values (0 in 0, 1 in 1, 2 in 2) into the flash memory and then dump the contents to a hex file. But having some trouble, doesn't seem to be working.

    When I open hex file in notepad I get:

    000001000200

    Any idea how to understand this?

    I am reading a source saying "Every line in a hex file always starts from colon". Hex code for ASCII colon is 3A. So... what gives?

    Would have been satisfied to see 000000010002 in hex file but alas no.
