Hello,

 

I'm trying to evaluate the linux enviroment in zedboard following the steps described in:

 

Zynq & Altera SoC Quick Start Guide [Analog Devices Wiki] 

 

after create the image with win32diskimage and extract the 3 files from zynq-zed-adv7511  folder (I just have the zedboard without any FMC)

 

I run the boot commands:

 

env default -asaveenv
setenv ethaddr AA:BB:CC:DD:EE:FF (I don't find the sticker)save reset

I get the serial output:

the files are in the base directory and of course the devicetree.dbt.

 

why I have this error?.
