AD-DAC-FMC-EBZ with AD9163 bring-up

Hello Everyone,

I hope you are all doing great! 

I am new to AD evaluation platforms and will first time use the Linux image on the following setup: 

HW: A10SoC+AD9163-FMCC-EBZ (Eval-AD916x) 

HDL: AD-DAC-FMC-EBZ 

config.tcl: AD9163 mode:08 (set params(AD9163,08) {2 8 2 1 1 16 16}) 

I would like to send out patterns read out from DMA (from DDR4) patterns 

My first question is : 

Which Linux image should I use for this purpose? 

Then What is the easiest way to feed the desired patterns over the DDR4 - DMA path to the DAC and get the maximum speed in the end as possible with this 8 lane configuration.

Best Regards,

Ömer.

  • Hi,

    As a starting point you can use the HDL design referenced here.

    Together with that you can use the latest Kuiper linux image but unfortunately the devicetree is not included in BOOT partition yet so you'll have to build one on your own using this devicetree source

    After that please try to use the IIO OSC tool already built in Kuiper image. With OSC tool you can load a waveform file and it will be streamed from DDR to DAC using the DMA.

  • Hello, 

    Thank you for the reply.

    The device tree source you mentioned is socfpga_arria10_socdk_ad9136_fmc_ebz.dts

    So is this also covering ad9163? 

    and can you suggest me a way to build it? 

    Best Regards,

    Ömer.

  • The devicetree I linked is targeted for https://wiki.analog.com/resources/eval/user-guides/ad-dac-fmc-ebz and it should support ad9163.

    You can follow the steps presented here: https://wiki.analog.com/resources/tools-software/linux-build/generic/zynq to build the device tree

  • Thank you, I have used the device tree from your link and followed the steps from here to build the Kernel and the Device tree https://wiki.analog.com/resources/tools-software/linux-build/generic/socfpga

    I have built also the FPGA project in Quartus and generated rbf and put all in the SDcard and booted. It seems boot is successful. 

    I have also the  EVAL-AD916X board attached to FMCA connector of the A10SoC.

    Now how can I verify actually that I have everything in place correctly? Are there some simple check points that you can suggest and any simple application examples to read/write registers and so on.. ?

    Best Regards,

    Ömer.

  • for example at the situation now, I don't have any iio devices appearing on the linux system. Is this normal? What should it look like to be said "it is OK to try some application now"

  • BTW - please don't open multiple threads for the same issue.

    Can you please provide your kernel startup messages?

    -Michael

  • Hello.

    I opened the other thread since I thought and I saw in other past threads comments that encourage to open seperate tickets once the initial question is answered, and I even thought that not doing so would be a reason to not getting response since the thread is getting longer and longer

    Aboiut the issue

    I dig into the problem more in the meantime. And I realized that the kernel modules are not present/installed and loaded. in other words usr/lib/$(uname -r) does not exist.

    I am trying to find out now: 

    1- How can I build the .ko files during the kernel compilation?

    2-How can I be sure that the rootfs has all the necessary files (including these modules built in 1-.  but are there any that I need to manually put in or somehow be sure with a script that all is in.)

    Below are the full startup messages. Hope not too long.
