Standalone System In Zedboard and FMCOMMS2

Good afternoon everyone,

I am working on a project to connect the Zedboard and FMCOMMS2 using the HDL workflow advisor.

What I want to do is to have the Zynq FPGA (PL, not the processor) generate samples of a sine wave and send these to the RF for transmission FMCOMMS2, and to have this system operating stand-alone, without any further connection to the PC running Simulink.

It seems to me that, the way I have the project set up, I need to keep Simulink connected to the board, even if it is not doing any processing. If I disconnect the ZedBoard from the PC, I get an error message on the PC. By "disconnect", I mean literally unplugging the Ethernet cable from the PC's port. The error message specifies that "a runtime error occurred in the System Object 'comm.internal.SDRTxZedBoardFMC234SL', while executing the 'stepImpl' method" .

I would also like to know if it's possible to save the generated bitstream into a bootable image, so that I whenever I turn the board on, I get the desired functionality. I have followed the instructions in the PicoZed SDR SpeedWay 2015 Training but it doesn' work. I

I have attached a Word document with more details about how I have my project set up; also, the project folder with all the files. I'd be grateful if you could take a look at it and see if I'm doing everything correctly.

Thanks for your help,

Hi Romel,
For some reason your links are not working. If this is for an educational setting please post this over at the digilent forum.

Hi Josh,

I will post the same question in the Digilent forum so far I have updated the links.

Hi Romel,
I'm confused, why do you care what the PC reports when you unplug? As long as Zynq continues to execute (and it should) you have what you're after, right?

RE: standalone on Zynq
I believe MathWorks refer to this as "Turnkey Hardware". They have it for FPGAs, but to my knowledge, not for Zynq SoCs yet.

The moderators of this forum are Zynq experts. A few of us have years of experience with MathWorks tools. However your best place for answers on their Workflow is @ Matlab Central - http://www.mathworks.com/matlabcentral/answers/index

Hi Matt,
Thanks for your reply.
You are right, I don't care what the PC reports when I unplug, but my goal is generated a complete project running by itself without the PC running Simulink. In other words, I want to achieve the same results that "PicoZed SDR SpeedWay 2015" but for my design (signal generator).
I have followed several tutorials to generate the BOOT.bin file and I assume that it is working. However, I am not very confident about the "devicetree.dtb", and "uImage" that I get from the "zynq-zed-adv7511-ad9361-fmcomms2-3" folder. This is reflected because the SD card with the new image is not booting in the ZedBoard, and there are some errors. I attached the messages from the Zedboard using a terminal.

Finally, I think the workflow is fine because it generates the project in Vivado, but I will ask experts in Mathworks for some comments.

Thanks again for your support.

Hi Matt,

Just to clarify, when I said "I am not very confident about the "devicetree.dtb", and "uImage" ". I believe that I should modify something on them to run my new project.

Thanks,

Romel
