Hi All,

 I have read in DM385 datasheet that it supports 3-wire spi (half duplex mode). But I do not know DM385 IPNC RDK (V3.5.0) kernel supports 3-wire spi or not. Can any one help me how to check 3-wire spi support in kernel?                  

Regards,

Tejash Patel

    Hello

    in my case, I use spidev that test app to test the spi 2.(kernel/Documentation/spi/spidev_test.c)
    it doesn't support 3-wire mode on ipnc_psp_arago package 04.04.00.02.
    ./spidev-test -D /dev/spidev2.1 -3
