USB RNDIS support for U5A5

[darshanmirajkar-eaton]

STM32U575 having Full speed USB and RNDIS enabled in zephyr, For U5A5 Supports USB High speed wrt to below attached image form datasheet.

It would be good to have support for USB and RNDIS enable for U5A5.

Or Someone suggest how to enable this.

This is already supported using following configurations:

USB Device Settings

CONFIG_USB_DEVICE_STACK=y

Select USB Configurations

CONFIG_USB_DEVICE_NETWORK_ECM=y
CONFIG_USB_DEVICE_INITIALIZE_AT_BOOT=n

CONFIG_USB_DEVICE_NETWORK_ECM=n
CONFIG_USB_DEVICE_NETWORK_RNDIS=y

@Desvauxm-st, can you have a look ?

[darshanmirajkar-eaton]

@Desvauxm-st do you have any update on this??

[darshanmirajkar-eaton]

@erwango @Desvauxm-st Any update on this.

@darshanmirajkar-eaton This is under investigation. If this point is critical for you, please contact your local ST support.

@darshanmirajkar-eaton We're facing an issue in U5 HAL. It appears this configuration isn't working on STM32Cube fw neither.
To speed up things, I'd suggest testing using CubeMX (using USB device API). You will face the same issue. Then you can raise an issue in https://github.com/STMicroelectronics/STM32CubeU5

@darshanmirajkar-eaton : see the word document sent to internal ST buzzila

I tried https://github.com/STMicroelectronics/STM32CubeU5/tree/v1.3.0/Projects/NUCLEO-U5A5ZJ-Q/Applications/USBX/Ux_Device_CDC_ACM with this also...USB is not initializing

Able to enable RNDIS in U5A5 that in v3.2.0. Suggesting to use PLL1P/2 or HSE as clock source for USB_HS block. For further check this

@darshanmirajkar-eaton As we now have a PR for USB OTG HS on the stm32U59x/5Ax with #76200, maybe you could re-test on your side.
What is the application you are running to have RNDIS enabled ?
