NVIDIA Orin Power Management

  • Provides an interface to Power-On/Off the Orin SOC
  • Provides an interface to set the GPIO pins for Boot-chain of Orin SoC while powering On
  • This is a stateless (independent of IST, SC7) Component as it acts on the commands from other SWCs on MCU which might hold the states and state management.
  • Detects HW Error scenarios like HW power-up failure detection via PG Signal from VRS10/11/12 and Orin rails, and the power-on is aborted.
  • Supports safe shutdown of Orin
    • During power-Off/ Reset request, Power Manager waits for Handshake GPIO to be set before powering off the VRS10.
    • A timeout of 20 seconds is provided in case the GPIO is not asserted.
  • Needs a Platform Power Management SW Component (provided as a reference code), which invokes the APIs provided by Orin Power Manager. The same requests are provided via the shell commands also.
