    I moved this question to the Blackfin Processors community.  Someone here should be able to assist you.

    Hello Ranjith,

    Support in what sense? Booting or simply interfacing ...

    for booting: the boot ROM of processor supports booting from 8/16/24-bit addressable SPI memories (with a READ opcode of 0x03). So, as long as serial flash supports the expected read sequence, it is safe at the timings side... Refer EE-240 for SPI flash boot timing.

    If you are using SPI flash for non-booting purpose, SPI can send as many address bytes as required.

    Make sure that other electric/AC specifications are acceptable.
