I am using two stm32H7A3ZI-Q board to transmit and receive data (which is a double). I am using HAL_UART_Tramsit and HAL_UART_Receive_IT to send and receive the data. When i connect Tx to Rx on the same board, it sends and receives data fine. The ima...

Yeah I agree. I don't know why this works and the other doesn't.

Cool, Thanks for the help. I think we have find a solution. i did this. SPITxCompleteFlag=0; HAL_SPI_Transmit_IT(&hspi1, TX_Data, sizeof(TX_Data)); while(SPITxCompleteFlag !=1){ } HAL_SPI_Receive(&hspi1, RX_Data, sizeof(RX_Data),100); ...

Thanks, Yes i am quite certain that is the issue. I dont know how to overcome this? Is there any techniques i could used?

Sure can, what is PS tho? Do you want a picture? I connect MOSI to MOSI, MISO to MISO, NSS to NSS, and CLk to CLK on each of the boards, using spi.

i not sure where "..." is. The trouble is that i can figure out how to send and receive. The figure above shows that.
