[ECOS] Enabling flash memory support (custom board)

["David Ho" <davidkwho@gmail.com>]

Hi,

I am attempting to enable AMD/Spansion flash support for redboot but
when I examined ecos.ecc, it is not active.

# AMD AM29XXXXX FLASH memory support
# FLASH memory device support for AMD AM29XXXXX
#
cdl_package CYGPKG_DEVS_FLASH_AMD_AM29XXXXX {
    # Packages cannot be added or removed, nor can their version be changed,
    # simply by editing their value. Instead the appropriate configuration
    # should be used to perform these actions.

    # This option is not active
    # ActiveIf constraint: CYGPKG_IO_FLASH
    #     CYGPKG_IO_FLASH == current
    #   --> 1
    # ActiveIf constraint: CYGINT_DEVS_FLASH_AMD_AM29XXXXX_REQUIRED
    #     CYGINT_DEVS_FLASH_AMD_AM29XXXXX_REQUIRED (unknown) == 0
    #   --> 0
};


Looking around, CYGINT_DEVS_FLASH_AMD_AM29XXXXX_REQUIRED is not set, I
suppose I should not set this manually and let the inference engine
figure it out.

The question becomes, how do I do that?

I have included in my ROM configuration IO_FLASH and DEV_FLASH_AMD,
enabled FIS and FCONFIG.

Is there anything I missed?

Thanks,
David
