Interface and connectivity ICs

Hello, I'm using a FTM32767ZI and trying to receive data from host using HAL_UART_Receive_DMA(). I enabled DMA settings for RX and generated code using STM32CubeIDE. However I can't receive any data by calling HAL_UART_Receive_DMA.

I already confirmed HAL_UART_Receive() can receive expected data. However I can't using HAL_UART_Receive_DMA.When I looked into RDR register (huart.Instance->RDR), I can see the first 1 byte of data sent from target is received. But the data isn't c...
