Kernel Panic booting Linux on Zynq w/ ADV7511

Hi,

 

I'm looking for help to following set of instructions "LINUX WITH HDMI VIDEO OUTPUT ON THE ZED AND ZC702 BOARDS"

 

http://wiki.analog.com/resources/tools-software/linux-drivers/platforms/zynq

 

I follow the instruction almost verbatim and consistently get a kernel panic error. The only modification is I build 'zynq-zc702-adv7511.dts' instead of the device tree listed in the sample commands. As per other threads, I'm using the latest available versions on the adi git repository for the IP cores and the linux kernel.

 

Output from the boot sequence is copied below. It appears the kernel crashes right when trying to start the init sequence on the file system (Linaro).

 

I'd very much appreciate any tips as to how to debug this issue.

 

Thanks,

Johnnie
