Zedboard hangs when running HL code

jesusmgonzalez

Hi!

I'm trying to run some High Level code generated from Matlab/Simulink. I set all kind of software optimizations regarding embedded destination platform, such as RAM optimization and complex reduction, as well.

But he problem arises when I try to run the first step. The Zedboard freezes and the XSDK returns a debug error. I don't know if the problem is related with memory consumption. The total reserved space in one iteration is at least 20KB of data.

Does anybody know how to solve this problem? Could I add any hardware accelerator in PlanAhead?

Thanks,

Parents

    Zedboard hangs is not enough information to help you.

     

    What version of the Xilinx tools and Matlab are you using?

    What is your host PC OS?

    Is your application standalone or running under an OS?

    What is the error returned by XSDK?

    What does your overall application in general and your Matlab generated code specifically attempt to accomplish?

    Is this code modeled on some existing app note or reference design? If so what is it and did it work on your platform?

    Do you have a baseline design that works at some point before you add your new code? It is generally a good practice to build up an application step by step as you develop it. In reverse, in debug, it is often useful to remove modules until the application no longer fails.

    Hi!
    Thanks for the answers and comments.

    - Matlab/Simulink versiu00F3n 2014 is used in order to generate C/C++ of a small Kalman filter (some matrices and vectors).
    - XSDK and PlanAhead used version is 14.7.
    - My host PC OS os Windows 7, and the application is suppoused to run on baremetal.
    - The XSDK returned error is lost of communication with the Zed, during debug mode or run mode.
    - Even when I generate a .mcs boot image, in the first step of the main function (I additionally turn on a LED) the blue LED indicating everything is done turns off.
    - The code is not in any existing App note.
    - The problem is that I think there is not enough memory to run the application without OS. Is there any method in XSDK to see the memory consumed by the running application, in debug mode?
    - I've done several other projects following the same steps, importing Matlab generated code into the Zedboard, and everything was fine. The problem is that I don't understand why the Zedboard hangs when try to run step by step my application, and why when I set the Zed on Flash boot at the very first step board configuration gets off.

    Thanks!
