Hi,

I am checking the UART TX linking with DMA. I am not getting the data serially. I am checking in tera term at PC end sending the helloworld string.

I generated code from the CubeMx. With out DMA it is working fine. I debugged that it is hanging the in the state of the UART_DMA_TX_BUSY state.

I am using the stm32f401re nucleo.

Can you please help me out.

Regards,
