Configuring devicetree for picozed sdr

Hi,

I am using PicoZED SDR/AD9361 and using the device tree combinations provided in analog devices linux kernel in arch/arm/boot/dts. I have used the 1) zynq-picozed-sdr2-fmc.dts and 2) zynq-picozed-sdr2.dtsi, but I am not sure whether they are correct or they need to be used in combination with the auto generated petalinux device-tree files (pl.dtsi, pcw.dtsi etc)? I am not able to access ad9361 and ethernet1 using the direct configuration. How should these device tree files should be used?

Thank you for your time.

Sincerely,

Abhinav

    Don't use auto generated devicetree files at all. zynq-picozed-sdr*.dts files only exists on older release branches.

    On the latest release they are called zynq-adrv9361-z7035*.dts.

    the .dtsi files are just common includes for the .dts files.

    If you use breakout carrier use zynq-adrv9361-z7035-bob.dts for the FMC carrier use zynq-adrv9361-z7035-fmc.dts.

    Please use these:

    dave@hal9000:~/linux/arch/arm/boot/dts$ ls -l zynq-adrv*
    zynq-adrv9361-z7035-bob-cmos.dts
    zynq-adrv9361-z7035-bob.dts
    zynq-adrv9361-z7035-box.dts
    zynq-adrv9361-z7035.dtsi
    zynq-adrv9361-z7035-fmc.dts
    zynq-adrv9361-z7035-fmc-rfcard-tdd.dts
    zynq-adrv9361-z7035-userspace.dts
    zynq-adrv9364-z7020-bob-cmos.dts
    zynq-adrv9364-z7020-bob.dts
    zynq-adrv9364-z7020-box.dts
    zynq-adrv9364-z7020.dtsi
