Hi,

Please tell me whether the virtual Uart take any hardware resoure (eg: actual UART port, PIN).

Does the virtual Uart support the baudrate change? If it support, what maximum speed it can support?

The virtual UART demo example in "STM32Cube_FW_MP1_V1.2.0/Projects/STM32MP157C-DK2/Applications/OpenAMP/OpenAMP_TTY_echo"

Rgds,

QiZhang

Hi @zqizh.1​ 

Virtual UART is a pure software abstraction concept to the IPCC intercommunication channel between A7 and M4. It does not take hardware resource.
