    Hello Mark Bul,<br>
    <br>
    I don't think that it's possible to extend the native address space
    onto an external<br>
    flash memory, which is probably driven by SPI.<br>
    <br>
    Do you really need 20 MB of coding size, or are parts of that<br>
    big files like pictures/videos/music files? Those can be loaded at
    runtime<br>
    and then accessed/worked on without problems.<br>
    <br>
    If you really need 20 MB of code, then I don't see a simple solution
    here.<br>
    You probably could split your program into small parts and load
    these parts<br>
    on demand from the SD flash memory into the SRAM of your
    microcontroller<br>
    and execute the code snip from RAM, but this degrades the overall
    performance<br>
    is very hard to maintain..<br>
    <br>
    Best,<br>
    Cenk<br>

        <div>The UDOO's hardware has 512KB of flash memory, but there's
          a possibility to add a micro SD card of 8GB or more, so since
          that my project is 20MB, is it okay or still it has to be less
          than 512KB? Because if I can't overcome that size then
          everything I did is wrong. That's why it's important for me to
          know it.</div>

                        <div>I'm new to this mailing list and to RIOT, I
                          hope I can have some help.</div>
                        <div><br>
                        </div>
                        <div>I want to use a board like the udoo where
                          to put RIOT and my program that I'm
                          developing, the question is: </div>
                        <div>since the udoo, as well as all the other
                          boards, have a limited amount of memory (ram
                          and rom) how big can my project be? </div>
                        <div>I'm developing a project which is more than
                          20MB of size is that too much? As far as I
                          got, usually the in the boards the ROM is
                          256KB or 512KB, but the udoo has the
                          possibility to put an external memory card, so
                          the available memory would be bigger?</div>
                        <div><br>
                        </div>
                        <div>I'm probably doing a lot of confusion and
                          I'm sorry if my question is dumb, but I hope
                          someone can clarify to me this thing.</div>
                        <div><br>

                        <div>Thanks. Cheers</div>
