Cannot configure pin PA for USB OTG FS

[AAzhi.1]

Hey ,

In the OTG block diagram (attached below ) pin PA11 and PA12 can be configured as OTG_FS but using CubeMx we can't set the functionality of these pins.

[AAzhi.1]

Is there any way to configure these pins?

What chip?

STM32MP1

That's not a chip number. There are 48 different chips within that family. Which one are you using? Seems like they all don't have USB FS.

Hi,

I confirm this is a limitation of CubeMX, you should leave them untouched in CubeMX and edit manually your Device Tree.

See https://wiki.st.com/stm32mpu/wiki/OTG_device_tree_configuration#DT_configuration_example_as_full-speed_OTG-2C_with_micro-B_connector

and https://wiki.st.com/stm32mpu/wiki/How_to_configure_U-Boot_for_your_board#USB_OTG_node
