Unable to handle kernel paging request

Hi people,

  I am trying to test the FMCOMMS4 with a zedboard, but I am unable to run the simplest test.


I download newest image (6 February 2015 release (2014_R2)):


For the configuration FMCOMMS4 + zedboard I used the boot files that are stored in zynq-zed-adv7511-ad9364-fmcomms4.


The image and everything else are the standard from the image, I didn't change anything.

the gunzip -c /proc/config.gz | grep ADV7  returns:





However when I boot I get the following error :



Unable to handle kernel paging request at virtual address 6c707478
