Other Parts Discussed in Thread: TM4C1294NCPDT

Hello,

I am working on TM4C1294NCPDT and I wanted to know if I could update/change the firmware over Ethernet without using LM Flash Programmer.

If so is there any document which would help me do so?

What steps I need to follow?

Can I do it on a custom made board rather than evaluation/development boards?

Thank you..!

    Chinmay,

    yes, this can be done. I do it on a custom board.  Refer to the example here: \TivaWare_C_Series-2.1.1.71\examples\boards\dk-tm4c129x\boot_demo_emac_flash

    Good luck!

    Hello Jeff,

    Thank you for showing the example.
    Also do you have any pointers for developing a host program on the PC which will have the firmware image to be burned?

    Thank you ..!!

    I'm not sure exactly what you are asking but I will tell you what I do.

    I have a Windows Test App that I wrote using Visual Studio. I have a button labeled "Update Firmware" that opens a new dialog. This new dialog has controls that allow you to enter the needed data: MAC Address of target, etc. (similar to what LMFlash has). I also have a "..." button to allow selection of the file to download. Once everything is set and the "Program" button is clicked, I call the "FlashUpdate( )" function in eflash.c. This file can be found in \TivaWare_C_Series-2.1.0.12573\tools\eflash. You will also need the BootP_server.* files in that same folder.

    I hope this helps.
