enet_io blocks TM4C129ENCPDT reprograming

Hi,

When i program enet_io from "TivaWare_C_Series-2.0.1.11577\examples\boards\dk-tm4c129x\enet_io" package, its blocking TM4C129ENCPDT to reprogram. When i try to reprogram it was throwing error as "Could not stop Cortex-M device. Please check the JTAG cable".


Note:- However initially i programmed uart_echo example, where i could reprogram it with modifications.

    Hello Dileep,

    The DK-TM4C129 board has a TM4C129XNCZAD device and not a TM4C129ENCPDT

    Hello Amit,

    I am not using DK-TM4C129, i have a board with TM4C129ENCPDT (custom made). I selected TM4C129ENCPDT target type before building the projects, uart_echo worked (only tx). when i flashed enet_io program i am facing the problem.

    Is there any way to reprogram that device again or erase the flash contents ?

    Thanks,

    Dileep

    Hello Dileep,

    The example that you took was from dk-tm4c129 which made me believe that you had TM4C129XNCZAD device. Have you made the change to the pre processor define of PART_TM4C129XNCZAD to be changed to PART_TM4C129ENCPDT, if the only change was that of a TM4C129 part?

    The only thing that you can do if you have a Stellaris ICDI is to run the Unlock Sequence so that Flash can be erased.

    Regards
