CC2650's sensor controller SPI question

Other Parts Discussed in Thread: ADS1292, CC2650

Hi,

In my project, I use CC2650's sensor controller to operate ads1292, comunicate by SPI.

1. first CC2650 initialize ads1292 by SPI, and that 's OK;

2.sensor controller read ads1292 result by SPI, and the MISO/MOSI waveform is OK, But the result read from spi all zero.

my sensor controller code:

for (U16  n = 0; n < ADS1292_RESULT_SIZE; n++) {

    U16 rxResult;

    spiRx16bit(SPI_POL0_PHA1; rxResult);

}
