I am using STM32H745 Discovery kit. I was running the example provided for UART but unable to see any message in Serial terminal. Checked on CRO but I am unable to see any data transmitted from TX pin (PB10).

I have directly connected the Tx of board to Rx of my computer and Rx of board to Tx of computer through the TTL to USB converter. I also checked the Tx and Rx of the board on DSO but was not able to see any data.

Synchronous SAI DMA stream NDT are not the same

As you can see we have difference of about 40 (betwenn S0NDTR and S1NDTR). since A is master and B is slave they must both start at the same time by HAL_SAI_Transmit_DMA but as you can see NDR is not the same. I also checked that their values are the...
