microblaze and external RAM

    Question: when I want to use a microblaze with external SDRAM, I guess I
    just have to connect an opb sdram controller to the instruction and data bus
    of the microblaze?! But how is my code coming into sdram? Do I have to write
    a sort of bootloader (running in block ram) that gets the program from flash
    to sdram or something? Or are there other ways to handle this.

    TIA,
    Frank

    You could hardwire a small rom component in vhdl, containing a small
    program, that could get the microblaze to transfer a bigger program
    between a flash module and the sram, and then jump to where ever you
    want to start in the sram.
