[U-Boot-Users] running U-boot on ML300 board??

Hello,

When running U-boot on ML300 board, I don't receive any character on the serial port.

I worked so:

*I downloaded a reference design given by xilinx. *With the xparameters.h, I compiled U-boot *I put U-boot in \sw\os\linux\kernel....I rename it on zImage.embedded.

*I generate my ace file, and nothing happens when running it on the ML300 board.

Have I done a mistake? Thanks
