Zedboard interfacing with AD-FCOMMS3-EBZ

I need to interface Zedboard with AD-FCOMMS3-EBZ.  I have prepared the SD card image as mentioned in the link: https://wiki.analog.com/resources/tools-software/linux-software/zynq_images.  The images which I have tried are : 22 June 2020 release (2019_R1) and 04 February 2020 release (2019_R1 RC). 

But the Zedboard is not booting. The following is observed on the console:

U-Boot 2014.07-dirty (Nov 20 2014 - 17:05:21)

It is given on the link mentioned above (reproduced below in bold text), to copy the images from subdirectory into the base directory. But there are no images files in the subdirectory corresponding to Zedboard+ADV7511+ADFCOMMS3-EBZ board file. The subdirectory has only BOOT.BIN file and a devicetree.dtb file and a zip file. I am not able to find the uImage in the subdirectory.  

The SD card includes a few images on it's BOOT partition. One of these images needs to be selected before the system will boot properly. In order to run any of these images, just copy the images from the subdirectory into the base directory, and then boot it. For newer versions of the SD card, uImage files are in subdirectories for FPGA board generation. Be sure to move the correct uImage into the root of the BOOT partition as well.

Please clarify whether base directory means BOOT partition of the SD card. What do you mean by "root of the BOOT partition"? Please let me know where the correct uImage can be found?

    Hi Rajesh,

    On the SD card there are 2 paritions visible a BOOT and a rootfs. If you use windows you will only see the BOOT partition. Inside it are a number of folders with the names of different projects along with the name of the board that they are designed for.

    For FMCOMMS3 you must copy the files from zynq-zed-adv7511-ad9361-fmcomms2-3 into the BOOT root outside of this folder. Another thing to copy is the uImage from the zynq-common folder, again in the root of the BOOT parittion.

    Regards,

    Mircea

  • Thank you .  It worked and I am able to view the IIO oscilloscope program. I am trying to capture FM radio as described in the link: https://wiki.analog.com/resources/tools-software/fm-radio.

     The following are my Receive chain settings:

    RF bandwidth: 22 Mhz, Sampling Rate : 22 MSPS, RX LO frequency: 87.399, RF Port Select: A_Balanced.

    Can you please explain what is the BNC connector connected to the RX1A of FCOMMS3 board in the figure below.

    I am not able to view the peaks in the frequency domain as explained in the link.

    My capture of the receive chain is given below:

    I tried to listen to the headphone jack of the zedboard but I am not able to hear anything. Please clarify?
