STM32U5A5 USB HS - Bare-Metal CDC Example

[inancmert]

Merhabalar,

https://community.st.com/t5/stm32-mcus-embedded-software/usb-hs-in-stm32u5a5/m-p/809596#M64236

I am writing to continue my question here.
When I checked the classic core middleware, I saw that it only supports the STM32U575 dev board.

I am using the STM32A5U5 development board. Can I run classic core middleware on STM32A5U5 development board? If so, how do I run it?

I need to work with bare-metal and CDC.

How do I structure the .ioc file?

Can you explain in detail?

Thank you for support.

Hi @inancmert 

You have 2 possibilities. You can either use USBX without threadX or classic core middleware without any RTOS.

1. You can start with the example provided here. Then remove :  use predefined buffer ux_device_byte_pool_buffer instead of dynamic allocation with tx_byte_allocate().

   #if defined ( __ICCARM__ )
   #pragma data_alignment=4
   #endif
   __ALIGN_BEGIN static UCHAR ux_device_byte_pool_buffer[UX_DEVICE_APP_MEM_POOL_SIZE] __ALIGN_END;​

   New knowledge base article about how to develop bare metal USBX application will be available within few weeks.
2. Using classic core middleware: you can get started with the attached example
