Setup ADRV9364-Z7020 with ADRV1CRR-FMC using MATLAB

Matlab has the whole instructions on how to setup the radio using Communication Toolbox for Zynq , I followed the procedure. But I have a doubt on switch configuration. I am trying to boot using SD card.I have tried with S1,S3,S4 On(position away from dot on switch). For some reason the LED DS3 which should've blinked suggesting successful boot, isn't happening. I even did a carrier rest according to the procedure and waited at least 5mins but it didn't work.

D3,D4 LED are ON continuously. 

I just took a random SD card and Matlab downloaded some files onto it, Is there anything I am missing? I am a rookie in the field, any help would be great. 

And is there any jumper setting? Currently all are open

  • Does that mean I can't use HDL coder or Embedded Coder from MATLAB?

    I saw many example designs based on MATLAB which used adrv9361, but is it valid to 9364?

    If I can't use MATLAB packages then what are the options I have?

  • 1. I would reach out to MathWorks to see if they have some support for this configuration.

    2. You can try the Transceiver Toolbox: It does have support for ADRV9364. We do not test ADRV9364+FMC but the BOB should work on the data path. I would first verify your board boots with the boot files provided on the SD card first. That will tell you if the combination functions.


  • I copied boot.bin and .dtb from bob-cmos folder to boot partition main directory, Switches s1,s3,s4 on ADRV9364 are ON(pointing away from the dot on switches), which I think does SD Card boot from the FMC Card slot. But I am only seeing D3,D4 LED's on SOM glowing continuously.

    On the FMC DS8,DS2  glows red.  I opened serial console using teraterm  but the terminal is blank. Please help me identify the problem with booting.

  • Someone with an ADRV9364+FMC will try out this configuration and get back to you.


  • Tested on my side using the 2021-02-23-ADI-Kuiper.img from here:

    Copied files from the zynq-adrv9364-z7020-bob-cmos and zynq-common folder.

    My switches are set same as yours.

    Initially all LEDs are like yours, but after a second D4 on the SoM turns off and DS7 on the carrier turns on. These LEDs indicate CFG Done. 

    So in case this doesn't happen. The FPGA didn't boot. 

    Typical root cause is SD card selector in the wrong position, or BOOTMODE set incorrectly.

    Can you try to:

    1) Use our latest boot files from the link above.

    2) Also try to use the SD Card socket on the SoM itself.

    3) Move the switches ON/OFF and make sure they are really in their end position.
