Embedded Vision Demo won't run

thosch42

Hi all!

My Embedded Vision Development Kit with Python-1300 camera module just arrived and I'm doing my first steps.

First of all, I saved the sd image from the Getting Started Guide to the sd card and run the kit from this image. Everything works fine.
Then I followed the steps described in the PYTHON-1300-C Reference Design pdf. The build of the design works well and the Synthesis as well as the Implementation runs without errors. Even the Compilation of the embedded software project in the SDK run without errors. So far, so good.
But when I program the FPGA and run the application, I get nothing. So it seems, that the provided sd-image and the result of the build process of the provided Reference Design is not the same.
So the question is, where did I get the right Reference Design?

Best regards,
Thomas

    Thomas,

    I will help you to get this design working.

    The design was built and tested on hardware before being posted online.  I will re-download, re-build, and re-test the design as an additional verification step.

    In the meantime, can you confirm if the pre-built BOOT.bin that is included with the design works ? (C:\AVNET_EMBV_PYTHON1300\2014_3\sd_image\microzed_7020\BOOT.bin)

    Also, can you provide the output of the serial console ?  This can provide additional clues to help resolution of this issue.

    Regards,

    Mario.

    Hi Mario!

    THX in advance for your help.
    The BOOT.bin included in the AVNET_EMBV_PYTHON1300... works very well.
    But if I just recompile the embedded software and and run it, I have no more HDMI signal, while the console output looks good to me.

    I just edited one text line, to see if it really is the code from the SDK.
    I also run the fmc_imageon_vita_receiver_sensor_initialize function in verbose mode, to see if the init of the camera works. But it look also good to me, except to "UNKNOWN CHIP_ID". Could this be the problem?

    This issue has been resolved, on a seperate forum post:

       http://zedboard.org/content/embv-python-1300-c-reference-design-not-working

    The problem turned out to be a defect HDMI cable.

    Hello Mario
    I am from china.I have a problem.I use the IP core "onsemi_python_cam" and "onsemi_python_spi"to debug Python 1300.
    theCRC reg is 0x0000000F all the time
    " VITA CRC - Status = 0x0000000F"
    I can't find the reason ,can you help me ?
