    hi , i referred the document we have an external nor flash ic for booting .

    we have on chip ram ip for copying the flash code . but i have to boot based on external pin .

    what should be used for my project,

    1. memory based boot copier

    or

    2. alt_load_function based

    i think i had to use memcopy based boot copier because i have to boot based on external pin triggering.

    so, how do i create memory based boot copier in the code .

    can u give a solution .
