hi all, when i use u-boot 1.1.5 boot kernel 2.6.22, no kernel console output, development enviorment i use: cross_compiler: arm-2007-eldk.iso
No console output can be caused by several things, all hard to debug since you are running blind.
I'm not an arm expert, but u-boot 1.1.5 is suspiciously old, especially when trying to boot a fairly recent linux kernel. Can you upgrade it?
Can you boot an older version of linux with your 1.1.5 u-boot?
Do you get any console output in the linux memory buffer? http://www.denx.de/wiki/view/DULG/LinuxPostMortemAnalysis
When you halt the processor with your debugger, what is it doing? Where is it? What procedure is it in? Can you get a stack trace to see where it came from?
Are you passing the right options on the command line to tell linux what console parameters are? (Is your "atag" info right? I'm ignorant of how this works, just know there is something there.) http://www.arm.linux.org.uk/developer/booting.php

Good luck, gvb
