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

[Queenie]

Yes.. U r right. Iam not using the ixdp425 (development) board.
What iam using is a customised board having IXP425.

On this board, I tried with the REDBOOT prebuilt utility for ixdp425 board (
development board) from the web and I could see the console message on my
hyperterminal. 

I was wondering y I cannot observe the same with my U-boot. is there any
extra configuration needed?

I checked the CFG_IXP425_CONSOLE macro in u-boot and saw thats its assigned
to IXP425_UART1 of the IXP425 chip. I also checked the circuit diagram of my
customised target platform and found that the console is connected to UART1
only.

What could be causing this problem?
