  • TM4C129DNCPDT: TM4C129DNCPDT Dual Application Firmware Update Strategy Using UART and Alternate Flash Regions

    Part Number: TM4C129DNCPDT Hi, I am working on a firmware update mechanism for TM4C129DNCPDT and would like guidance on the best approach for dual-image firmware management. Current Requirement We receive application .bin files through UART and…

  • TM4C129DNCPDT: Does NMI Pin(PD7 - TM4C129DNCPDT) can act as normal gpio input interrupt pin with falling edge?

    TI Thinks Resolved
    Part Number: TM4C129DNCPDT Hi, I have a question regarding the NMI pin. Can the NMI pin be configured and used as a normal GPIO input pin? If yes, is it possible to configure it to generate a falling-edge interrupt? Currently, I have: Unlocked…

  • TM4C129DNCPDT: NMI intrupt not working properly

    TI Thinks Resolved
    Part Number: TM4C129DNCPDT I am trying to use PD7 as an NMI input on a TM4C129DNCPDT. Requirement: PD7 should be idle low. When PD7 transitions from low to high (rising edge), the MCU should enter the NMI handler. Inside the NMI handler, I want…
