Hello @chenchenchen1122 and welcome to the ST Community
Sorry but i think my first answer was not as clear and complete as it should be. Infact, as mentioned on the paragraph 11.1 of the UM2569:
- Some boards feature a specific STM32 device version, which allows the operation of any bundled commercial
stack/library available. This STM32 device shows a “U” marking option at the end of the standard part number
and is not available for sales.
Best Regards.
