PS not responding

Former Member

Hi,

I am trying to run a simple helloworld+led-blink application on the Mini-ITX. I have tried JTAG, QSPI, and SD Card configuration, with varying results.

Using JTAG, I am able to program the PL, but the PS does not print "hello world" over UART, and the GPIO-controlled LEDs do not blink.

Using QSPI, the PL never gets programmed and the PS also does not run my helloworld app.

Using SD Card, the PL gets programmed, but the PS does not run my helloworld app.

Everything works perfect when I program the Mini-ITX with the provided .mcs and .bit files from the "zynq_mini_itx_7z045_embedded_design_v2015_2" project.

Furthermore, I can successfully run a helloworld app on the standard Zedboard, but not on my Mini-ITX board.

I can't figure out why the Zedboard works fine but the Mini-ITX is having this problem. For each of these boards, I have used the correct board files and constraint files. I am running Vivado 2015.4.

Can anybody provide some troubleshooting steps I can take?

Thank you

    Hi Gary,

    Thanks for your suggestions.

    I updated to 2015.4, verified that the MD5 checksums matched, regenerated and rebuilt everything, and the issues remained.

    I verified that I was using the correct board files as well.

    Then, I downloaded and installed 2015.3, and verified that the MD5 checksums matched. After rebuilding everything from scratch, again with the correct board files, and then creating a new SDK project, I still saw the same issues.

    Running the app with SDK debugger also does not help.

    What else can I check or do? By the way, I am able to connect to the PS through XMD, write to the LEDgpio addresses, and control the LEDs.

    Thank you
