- 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.
Khouloud.
