I’m trying to use USART + RTS only + DMA(non circular, peripheral to memory, DMA1 Stram0) on STM32H755ZIT6’s M4 processor.
My code is working on M7 but it does not works on M4 and I’m getting Framing Error , which means that the stop bit is not recognized on reception at the expected time

I would like to receive any length of data from USART2 DMA circular mode, then transmit the identical data via USART1 DMA normal mode.
