DRV8305: DRV8305 SPI SDO pin no output

Part Number:DRV8305

Hi,

I have a DRV8305 connected over SPI to a STM32F334

I have a 1k5 pullup on the SDO pin.

The SPI is configured as:

    spi.SPI_Mode            = SPI_Mode_Master;
    spi.SPI_Direction        = SPI_Direction_2Lines_FullDuplex;
    spi.SPI_CPOL            = SPI_CPOL_Low;        /* CPOL=0 -> Low    */
    spi.SPI_CPHA            = SPI_CPHA_2Edge;    /* CPHA=1 -> 2Edge    */
    spi.SPI_NSS            = SPI_NSS_Soft;
    spi.SPI_BaudRatePrescaler    = SPI_BaudRatePrescaler_64;
    spi.SPI_FirstBit        = SPI_FirstBit_MSB;

I am unable to get any data from the SDO pin.

Any idea, as what maybe causing the issue ?

Thanks in advance

Manu
