NVIDIA Orin IST Manager

NVIDIA DRIVE Orin™ IST Manager

  • Provides an interface to set the IST Configuration. Communicates the configuration set by the user application to NVIDIA DRIVE Orin™ software (IST Client) over Ethernet (for Key-On/OFF Orin IST).
  • Provides an interface to read the IST results.
  • Provides interfaces using which the Platform Power manager can query if a Keyon/KeyOff IST must be executed, and query whether IST is completed.
  • During bootup, decides whether NVIDIA Orin should be in IST Mode or Normal mode.
  • Triggers IST by GPIO assertion, monitors the execution of IST on NVIDIA Orin and detects IST stuck scenarios through timeouts.
  • Provides an interface to abort the IST execution.
  • Detects and handles the following HW Error scenarios.
    • IST stuck is detected by a GPT-based HW timer with a configurable timeout.
    • Communication with NVIDIA DRIVE Orin™ SoC is monitored by a software timer with a configurable timeout.
  • Depends on an active Ethernet (VLAN200) connection between MCU and NVIDIA Orin.
  • The customer application is expected to set a valid IST configuration during every power-cycle, using the interfaces provided by NvMCU_ISTManager. This is done using the Serial console Shell Commands.
