VHDL DE2 board - write bmp file to SDRAM display via vga

Hello all,

I'm trying to save a bmp file to the sdram on altera DE2 board and display that file, via the vga dac, on screen.

i have manged to find a vhdl code for the vga part, but having trouble using the sdram.

i am a beginner, i have tried to use Qsys with it's tutorial and came across some problems, for example there is no .sof file to select for the Altera Monitor Program (in the new project wizard - specify a system).

hope someone could help me.. thank you :D..

    I'd start with a working example project for your board that uses the SD ram. Use a copy of that as your starting point. Make small changes to implement the other functions you need. Start with simple stuff. Walk before running etc.

    thank you galfonz. i think i'll check how to use the M4K blocks (cyclone II). Maybe anyone have a working example of a vhdl code to read and write from the M4K in the fpga?

    thanks everybody..
