Peripheral USB OTG[edit | edit source]

The USB OTG is a dual-role device (DRD) controller that supports both device and host functions and is fully compliant with the On-The-Go Supplement to the USB 2.0 Specification. It can also be configured as a host-only or device-only controller, fully compliant with the USB 2.0 Specification.

Description[edit | edit source]

The USB OTG interface available on ETRA SoM is based on STM32MP1 SoC.

The USB OTG port supports the following standards and features:

  • it is USB-IF certified to the Universal Serial Bus Specification Rev 2.0
  • integrated support for A-B device identification (ID line)
  • integrated support for host Negotiation protocol (HNP) and session request protocol (SRP)
  • it allows host to turn VBUS off to conserve battery power in OTG applications
  • it supports OTG monitoring of VBUS levels with internal comparators
  • it supports dynamic host-peripheral switch of role

Pin mapping[edit | edit source]

The Pin mapping is described in the Pinout table section
