Peripheral USB Host[edit | edit source]
USB host controller supporting the standard registers used for full-speed (OHCI controller) and high-speed (EHCI controller).
Description[edit | edit source]
The USB Host interface available on ETRA SoM is based on STM32MP1 SoC.
The USB Host port supports the following standards and features:
- two physical ports supported using an on-chip 2-port high-speed PHY
- the second port is shared with USB OTG peripheral
- supports OHCI model for full- and low-speed operation
- supports EHCI model for high-speed operation
- LPM (link power management) support
- DMA engine with local 512 Byte packet buffer
Pin mapping[edit | edit source]
The Pin mapping is described in the Pinout table section
