TM4C129XNCZAD: TM4C129XNCZAD Ethernet Bootloader

Part Number: TM4C129XNCZAD
Other Parts Discussed in Thread: EK-TM4C1294XL

Hello TM4C Microcontroller forum,

I am trying to build an Ethernet based boot loader for my TM4C129XNCZAD device.

I cannot find any examples codes in the latest Tivaware (I have 2.1.3.156) for my device. I browsed through the forum and other resources to find a good starting point but could not find something specific - either the device is different or examples use UART, etc. for the boot loader.

My questions:

- Are there specific examples for ethernet boot loader for the TM4C129XNCZAD?

- If no specific examples, what would be the best place to start? Should I start looking at the (Tivaware 2.1.3.156) examples for the EK-TM4C1294XL and modify to run on the TM4C129XNCZAD?

Thank you - any help is greatly appreciated.

Robert

    Hello Robert

    The example you should be referring to in the TivaWare is

    D:\ti\TivaWare_C_Series-2.1.3.156\examples\boards\dk-tm4c129x\boot_emac_flash

    Which is the flash based Ethernet boot loader. You can also use the ROM ethernet boot loader for devices which are in factory reset condition and require the vanilla boot loader. Is this a custom board that you have or are you using the DK-TM4C129X

    Hello Amit,

    Thanks for your reply.

    Yes, it is a custom board.

    I will take a look at that example code and get it build for my architecture.

    Thanks,
    Robert
