About STM32F072 device , Problems when use HAL_SPI_Receive function of HALL in single wire and half-duplex mode.

[hzhu.17]

Hlello. I want to use single wire and half-duplex mode for spi master.Init works, and HAL_SPI_Transmit function works .But it will go to timeout when call ​HAL_SPI_Receive function from HALL. it still can't get RXNE FLAG . I measured it , it didn't generate clock. I read code, it should follow datasheet.   I don't konw why. Has it bug of the function ?

Thanks a lot if somebody can help me .
