AD-FMCOMMS1-EBZ Zedboard problems with a custom design

Former Member

Hi,

I'm working with a Zedboard and I have correctly implemented the reference design from here:
http://wiki.analog.com/resources/eval/user-guides/ad-fmcomms1-ebz/reference_hdl

Now I'm interested in creating my own design from the reference design. I have just removed the modules HDMI, spdif, GPIO and modified the DTS file but I still cannot communicate with the board AD-FMCOMMS1-EBZ. I attach the response I get when booting Linaro Linux OS through a SD card:

Welcome to Linaro 12.09 (GNU/Linux 3.6.0 armv7l)

How can I solve the problem of the SPI communication?
How does it affect my design when removing any hardware module from the reference design?

Thanks.

    In response to your question 'How does it affect my design when removing any hardware module from the reference design?'

    1) DeviceTree

    Generally you must remove DTS nodes for the cores you removed from the PL. Furthermore, XPS will reorder the IRQ numbers when you remove a peripheral, and you will need to ensure the updated IRQ numbers for the remaining peripherals match those in the the DTS file. You can see the IRQ numbers in XPS when you click on the block above the 'IRQ' label on the Zynq pane. Finally, the IRQ values in the DTS need to have 32 subtracted from numbers shown in the XPS dialog. For example, 91 becomes 59, 90 becomes 58, etc. After updating the DTS, generate an updated DTB and copy it to the FAT32 partition on the SD card as 'devicetree.dtb', overwriting the previous version.

    2) BOOT.BIN

    The SD card contains the Linux zimage, devicetree.dtb and BOOT.BIN in it's FAT32 partition. When modifying the PL, you must re-generate BOOT.BIN with an updated bitstream. It isn't clear from your post whether you did this. If not, then you can take a look at the Intro and Linux trainings here on zedboard.org for instructions on generating BOOT.BIN and updating the SD card.

    Thank you so much DSP_1!!!
    The problem was the IRQ numbers in the DTS file. I was going crazy, I could not see that detail before. So thank you very much for showing me the light ;).
