    using ST7FMC in SPI slave mode for full duplex,

    master can receive the data from MISO pin of ST7FMC once,

    but easily failed to get data from MISO anymore afterward,

    possible damged in MISO pin??

    the MOSI is OK to get data from master,

    any comment?

    have you checked the SS signal? making sure it goes high after the first data transfer?
