The BMC Module is one of the components of the NVIDIA IGX Orin Boards Kit. Baseboard Management Controllers (BMCs) provide a standards-based interface to system management and recovery.
The following list provides the functions and features of the BMC Module.
DCSCM-2 specification-compliant connector and I/O interface.
Console access by Ethernet.
Local UART comm port to IGX Module debug UART for console access to NVIDIA Orin CPU.
Ability to reset the IGX Module.
Ability to control power and report power status of the IGX Module.
Access control (authentication or authorization) for restricting use.
Ability to reprovision the IGX Module firmware.
Connections to all devices with updatable firmware, which allows it to update all device firmware on the motherboard including:
Support for securely updating the BMC Module firmware.
Includes ERoT for BMC Module secure boot.
Authentication of BMC Module firmware performed by RoT.
Communication channel between BMC Module and Safety MCU for data sharing and safety MCU firmware updates.
Access to telemetry data of the system including relevant temperatures, voltages, currents, performance status, M.2 drive SMART status, and fan speeds.
PCIe Endpoint to IGX Module for the purposes of remote access to application software control and monitoring.
