[U-Boot-Users] Blank console with IXDP425 in U-boot-1.1.6

Could it be that your hardware uses a different UART?
I had similar problem with a board of my customer that used different
UART. in his case the change was simple, just change
CFG_IXP425_CONSOLE from IXP425_UART1 to IXP425_UART2 in
include/configs/ixdp425.h

Check the UART in you board.
