Here is my log. It stops at the "done, booting kernel." I tried setting the console to ttyAM0 and no change. I don't think its booting as I don't see the LCD flash and no penguin. The odd this is that I built the latest kernel for iMX and this uboot will boot it. I also included my u-boot
Do you mean you are able to boot a mainline kernel, but not a 2.6.35 kernel?
environment settings at the end.
U-boot environment settings:

Please change it to ttyAM0.

If you boot a 2.6.35 you need to use ttyAM0.
console_fsl=console=ttyAM0console_mainline=console=ttyAMA0netargs=setenv
This line seems to be without any spaces. Are you sure this is correct?
Make sure your kernel command line passes ttyAM0 instead of ttyAMA0 if you want to boot a 2.6.35 kernel.
