hey,
I'm trying to boot Linux-kernel on ml507 Virtex 5 (powerpc),
I make all steps in this tutorial:
http://xilinx.wdfiles.com/local--files/embedded-linux/uboot-ml507-howto.pdf
and use the newest verstion of tool and Kernel from
http://git.xilinx.com/
but in I boot the kernel I get folowing error:
=> printenv
