Redboot, FLASH configuration using PowerPC

["Smith, Keith" <Keith.Smith@xxxxxxxxxxxxxxx>]

I'm using eCos 3.0. I'm running my Redboot in ROM mode. Redboot comes up, but gives the following error.

        FLASH: driver init failed. Invalid FLASH address.

I have determined that the 'Invalid FLASH address' error, CYG_FLASH_ERR_INVALID, is generated in cyg_flash_get_info() and find_dev(). Both functions are in io/flash/v3_0/src/flash.c.

I am running Redboot on a PowerPC. The flash part is an AMD 29LV160 (2 megabytes). Redboot is loaded at a 1 megabyte offset.

Below are details of my configuration.
I have no errors in the build nor any conflicts.

What have I failed to configure properly?

Here is the package list for my target.
      packages        { CYGPKG_HAL_POWERPC
                          CYGPKG_HAL_POWERPC_PPC60x
                          CYGPKG_HAL_POWERPC_ICM12
                          CYGPKG_DEVS_FLASH_POWERPC_ICM12
                          CYGPKG_DEVS_FLASH_AMD_AM29XXXXX
                          CYGPKG_IO_PCI
                          CYGPKG_DEVS_ETH_ICM12
                          CYGPKG_DEVS_ETH_INTEL_I82559
        }

Here's the CDL file for CYGPKG_DEVS_FLASH_POWERPC_ICM12:
cdl_package CYGPKG_DEVS_FLASH_POWERPC_ICM12 {
    parent        CYGPKG_IO_FLASH
    active_if       CYGPKG_IO_FLASH
    requires        CYGPKG_HAL_POWERPC_ICM12

    compile       icm12_flash.c

    # Arguably this should do in the generic package
    # but then there is a logic loop so you can never enable it.
    cdl_interface CYGINT_DEVS_FLASH_AMD_AM29XXXXX_REQUIRED {
        display   "Generic AMD flash driver required"
    }

    implements    CYGINT_DEVS_FLASH_AMD_AM29XXXXX_REQUIRED
    requires      CYGHWR_DEVS_FLASH_AMD_AM29LV160
}

>From Configuration:
Base address of flash device redboot should use: 0
Which block of flash to use: -1
