Does STM32U585 supports USB RNDIS ?

[NM.1]

Hi All,

I am starting work on USB RNDIS support for STM32U5, and completely new to this.

I am looking for example/documentation on USB RNIDS support on STM32U5.

Can anyone please help here ?

Hello @NM.1​ ,

There is no RNDIS example within STM32CubeU5 MCU package.

You may use examples provided on Microsoft Azure RTOS repo in order to develop your own RNDIS application.

We are currently working on adding multiple USBX classes to our packages including RNDIS.

Thank you for your understanding and your contribution.

The RNDIS class is provided with STM32Cube.

You can find it under ...\STM32Cube\Repository\<Your library and version>\Middlewares\ST\STM32_USB_Device_Library\Class\CDC_RNDIS.

A good starting point would be a CDC virtual serial port project, then modify it to the RNDIS structures und modules. The basic structure and calls are pretty similar.

Documentation for the RNDIS class (and all others) is here wiki.st.com/stm32mcu/wiki/Introduction_to_USB_with_STM32#CDC_Remote_Network_Driver_Interface_Specification_-28RNDIS-29_Sublass.

If the class is not provided for STM32U5 MCUs you can "steal" it from another models, like L4 or F4. Just install the Cube support for one of these, parallel to the U5 library.

The effort on integrating the stuff, and making it work is however completely on your side.

This will work for me.
