I ques what there is some CubeMX error because in stm xxx_hal_dma.h file this uart is added to list:

#define GPDMA1_REQUEST_USART6_RX      117U     /*!< GPDMA1 HW request is USART6_RX      */
#define GPDMA1_REQUEST_USART6_TX      118U     /*!< GPDMA1 HW request is USART6_TX      */

 For now I will try to setup manually, but I still on question about this issue ?
