Zynq Base TRD 14.1 On Zedboard?

e14 Contributor


Has anyone had any luck getting the Xilinx Zynq Base TRD 14.1 running on the Zedboard?  I know it is intended for the ZC702 Evaluation Board, but I hoped the hardware would be similar enough to get close.

I tried just installing the binaries on the SD card and booting it, but it hung on:

INFO : Initialize HDMI OUT

The TRD is along the lines of a potential application, so I would like to see it run if it isn't impossible.

    Hi.
    I made my ZYNQ board. It has DDR3 512MB. I used reference example "zynq_base_trd_14.2".
    I did boot linux kernel(v3.3) already but I had a problem with video driver(xylonfb).

    The video frame buffer's address is 0x30000000 ~ 0x37FFFFFF at ZC702 because it has DDR3 1GB.
    So I changed it "0x10000000 ~ 0x17FFFFFF" at DTS file, because my board has 512MB.

    DTS modification
