[U-Boot-Users] problem to load uImage but not zImage (onvirtex-4 board)

[Guillaume Berthelom]

Hi,

I find my problem! it was like you said a problem with the command line 
in u-boot. I had defined  CONFIG_EXTRA_ENV_SETTINGS before 
CONFIG_BOOTARGS, that's it! and you have to do the opposite.

Thanks for your help,
Guillaume Berthelom
