Hi Ovidiu,
You can't change the REF CLK frequency from the GUI.
You have to edit the device tree:
https://github.com/analogdevicesinc/linux/blob/xcomm_zynq/arch/arm/boot/dts/adi-fmcomms2.dtsi
If you have updated you boot partition recently - you should find this file also in your SD-Cards' FAT partition.
You can edit it there using your favorite editor.
clocks {
ad9361_clkin: clock@0 {
#clock-cells = <0>;
compatible = "fixed-clock";
clock-frequency = <30720000>;
clock-output-names = "ad9361_ext_refclk";
};
};
Once done - reboot your board and run the adi_rebuild_devicetrees.sh script.
root@linaro-ubuntu-desktop:/usr/local/src/linux_image_ADI-scripts# adi_rebuild_devicetrees.sh
CURRENT BOARD CONFIG: /media/boot/fmcomms5
Updating /media/boot/fmcomms5/devicetree.dtb -> /media/boot/devicetree.dtb
DONE
After that type: reboot
root@linaro-ubuntu-desktop:/usr/local/src/linux_image_ADI-scripts# reboot
