Tips and Tricks

External AD9361 reference clock via J1

An external reference clock can be supplied via J1. To switch the source, modify the arch/arm/boot/dts/zynq-adrv9361-z7035.dtsi device tree:

clocks {
    xo_40mhz_fixed_clk: clock@0 {
        #clock-cells = <0>;
        compatible = "fixed-clock";
        clock-frequency = <40000000>;
        clock-output-names = "XO_40MHz";
    };

    ad9361_clkin: clock@1 {
        #clock-cells = <0>;
        compatible = "gpio-gate-clock";
        clocks = <&xo_40mhz_fixed_clk>;
        enable-gpios = <&gpio0 105 1>; /* Set to 1 for extern AD9361_CLK */
        clock-output-names = "ad9361_ext_refclk";
    };

The ACTIVE_LEVEL for enable-gpios:

• 0 (active high) — use on-board XO

• 1 (active low) — use external clock via J1

Update the clock-frequency property with the exact frequency of the external supplied clock, set enable-gpios = <&gpio0 105 1>, then rebuild and install the modified device tree on the target.
