DK-TM4C129X boot demo flash

SL

Does the boot demo flash require a specific version of the DK-TM4C129X?  I'm trying to load the boot_demo_flash example that was included as part of v2.1.2.111 examples but it doesn't appear to be working.  The example builds in CCS and I'm able to load it onto the DK but the it doesn't appear to be working.  I see the title "boot_demo_flash" on the screen but I don't see any of the other messages, such as "Waiting for link" or "Waiting for IP Address".  The DK was shipped with v2.0.1.11577 examples which didn't include the boot_demo_flash example, so is there a specific version of the DK that I need in order for the example to work?  If so, then is there something that I can do with the version of DK that I have in order to get the boot_demo_flash example to work.

Thanks.

    Hi SL,

    This example project is intended for use with flash based Ethernet boot loader (boot_emac_flash). You need to program the boot_emac_flash code to the flash at 0x00 (defined in cmd file), and use Ethernet tool (for example tftp) to upload the application code (boot_demo_flash)to the flash at APP_START_ADDR (0x4000 defined in bl_config.h).
