Hi,

Does stm32f429zi support usb in hs mode? i found that PB 14 is required by USB-HS but on that pin red led is connected.

Thanks for support.

Hi

Doe.Joe

‌,

  • In deed, the STM32F429ZI supports the USB HS mode. The OTG_HS interface supports anULPI interface for external HS PHY ; The ULPI interface needs PB13 as ''OTG_HS_ULPI_D6'';

  • I think you are using an STM32 Nucleo On this board:

    • A red user LED is connected to PB
    • If jumper JP7 is present, the PB13 pin is connected to Ethernet PHY as ''RMII_TXD1''.

Since you need this pin for USB HS transfers,please follow the steps below:

1. Configure the PB13 as ''Reset State''.

2. Configure the External Phy depending on your needs (OTG/Dual_Role_Device, Host_Only, Device_Only).

You will notice that the CubeMX tool has configured all the pins needed by the ULPI interface.
