Zedboard doesn't boot with Xilinx 2015.2 Release

Former Member

Hi, all. I seem to be having issues getting to the Zedboard to boot using the files in the Xilinx Zynq 2015.2 release tarball (http://www.wiki.xilinx.com/Zynq+2015.2+Release). I copy the ramdisk and uImage kernels over to the SD card, and the Boot.bin and DTB from the zed subdir from that release. However, it seems to hang "Starting kernel ..." and never recovers.

I've seem this same issue with releases from 2013.4 through 2015.2. None of those will boot. However, 14.7/2013.3 will boot. What is the work around for this? If this is an incorrect setting in the DTS for the zedboard, what setting is incorrect? Is this only an issue with older boards? I've had mine for just under 2 years now.

Thanks,

-Dirv

    Could this issue be related to GPIO Support? See https://forums.xilinx.com/t5/Embedded-Linux/Zedboard-hangs-at-quot-starting-kernel-quot/td-p/368313

    That being said I've tried to disable that referenced option to no avail. It seem to be required. From menuconfig screen:

    Thoughts?
