Zedboard Newbie

go_er00

Dear Sir:

     I am new to the Zedboard system.  I just purchased a Zynq-7000 EPP 7Z020 Zedboard kit, downloaded the ZynqSW_Online_v03 and began to do the labs.

     When I got to lab 5 and I began to do the memory test, I discovered that my program "hangs" when I get to the 8 bit test.

     This is what I see:
 
--Starting Memory Test Application--
NOTE: This application runs with D-Cache disabled.As a result, cacheline requests will not be generated
Testing memory region: ps7_ddr_0
    Memory Controller: ps7_ddr
         Base Address: 0x00100000
                 Size: 0x1ff00000 bytes
          32-bit test: PASSED!
          16-bit test: PASSED!
           8-bit test:

      Lab 4, Experiment 3, steps 5 and 6, mention the 8 bit test but do not go into detail about any changes which need to be made in the program setup. 

      Can someone please provide me with a remedy for this issue?

    Not sure what would cause this error if the lab was implemented correctly. You could load the 'solution' for that lab that is included in the archive to verify that your hardware setup is correct.

     

    Just a note. The free webpack version of Vivado 2014.4 has all of the capability of the Design Edition except for the Vivado Analyzer.

    Dear Gary;

         I found out why the program was "hanging" and I got the program to run correctly.   The source of the problem was memory "allocation"  (Lab 4, Experiment 3, Step 3).

         Although I got the program running, at this stage of development, the "absolute noobie level," one isn't certain whether the software was installed correctly or not.  There was a lot of software to install.  This was the absolute very first program run using I/O and there is a lot of uncertainty when the first program run is made. 

         To test whether the software is installed correctly or not, there were some lab solution files that were provided to the user.   The files were created in the *.LAUNCH format.  However, literature on how to use the *.LAUNCH format is not provided.  Of course, one could "theorize", guess, how to correctly import the file but this is not the same as knowing with certainty how to use the file.  I guessed on how to import the file, however, although the compiler did operate, what I saw on the program output was open to interpretation.  It is important to know how to "formally" use the *.LAUNCH lab solutions within the IDE. I may start a new thread if I encounter another problem.  If you happen to see another discussion about using the *.LAUNCH file, I just wanted you to understand the rationale of why this discussion is relevant.  Also, second question that will follow the how to use the *.LAUNCH file is, what are the limits of this file as a remedy (what pre-conditions are necessary for this file to operate correctly).

         I would like to thank you for your prior technical support.
