[U-Boot] U-boot on xup-ml509 board

Hello,

I have been working with Leon3 on a XUP-ML509 ( http://www.xilinx.com/univ/xupv5-lx110t.htm) and I have ported the u-boot for this board.

In the u-boot execution I have a problem with the flash:

Flash: 32 MiB *** Warning - bad CRC, using default environment

Following some readings in forums, to solve this problem I made the "saveenv", but then the execution stops.

Also, when the flash is unlocked, the execution stops before.

What can be the problem?

Have somebody worked with this board?

Thanks in advance, Wesley
