Bpmp api

Hello,

I’m trying to follow instructions in the NVIDIA Xavier Series System-on-Chip Technical Reference Manual sections 7.2.3.3.2 & 7.2.3.3.5, which refers to:

using the BPMP software API

Use BPMP_FW API

In the TRM Boot and Power Management Processor (BPMP) section 4.1.1, this is stated:

Note: The BPMP processor runs NVIDIA supplied software and is controlled through an NVIDIA API. Details of the hardware programming interface are not supplied in this document.

What is the BPMP API and where can I find documentation on how to use it?

For reference, these references to the BPMP API are here:
TRM 7.2.3.3.2, SLVS-EC Initialization
TRM 7.2.3.3.5, SLVS-EC Enabling INCLK to SLVS-EC Sensor
TRM 4.1.1, Boot and Power Management Overview
