    Hi,

    I did this testing in RM57 Launchpad:

    LAUNCHXL2-RM57L Development kit | TI.com

    I am attaching both bootloader and application projects that i used for the reference.

    Hercules_Ethernet_Bootloader_RM57.zip

    LED_Blinky_RM57_At_0x20020.zip

    The first project is ethernet bootloader, and the second project is LED blinky project which will blink two user LED's on launchpad for every one second.

    I will explain what are the steps i followed to work with ethernet bootloader, here i performed static IP method instead of using DHCP 

    1. First configure proper static ip, subnet mask to the target board based your PC ipconfig

    For example 

    My PC ipconfig is here.

    So, i configured my target PC static ip, subnet mask as follow.

    2. Now build the ethernet bootloader code and program it into the Target board. Once programming is successful connect a ethernet cable between your PC and target board.

    3. Now reset the board then you should get below data in serial port.

    Note: Here serial configuration is, baud rate-19200, stop bits-2 and No parity

    4. So static ip got assigned to the board, now open Tftpd32 tool to program the application through ethernet bootloader.

    5. Do below configuration in Tftpd32 tool

    At server interface, select your PC ip address. And select Tftp client menu, also give target ip at Host field and give port number as 69.

    6. Once you did the proper configuration in Tftpd32 tool now select binary file path at local file field

    This should be the binary file of the application you want to program through ethernet. In this case the binary file i provided in example application.

    7. Once you select the binary file now you can click on "put" option to send binary file over ethernet.

    8. Now you can see the target board programming steps through serial port as below

    It will erase the necessary sectors in the flash to program the application and it program the flash in blocks wise.

    9. Once programming the application, now make sure to connect GIO_A7 to the 3.3v 

    As i am using launchpad i shorted J1 connector 1st and 5th pin.

    10. Once you short GIO_A7 to the 3.3v then now reset the board to run application code by ethernet bootloader

    And user LED's should blink on launchpad.

    Here i used static IP right, if you want you can connect PC and target board to the router and assign dynamic IP's and can perform the step 3 onwards.
