Do you mean zImage.embedded? I have been using make_image utility from
uboot and using image arch/ppc/boot/images/vmlinux.gz to create image that
uboot downloads via tftp.

I tried changing the baud rates didn't make any difference. If I attach
the BDI it is looping in serial_console_write. I did verify that clock
rate is getting passed from uboot to kernel correctly. In uboot I am
not setting the variable clock_in_mhz.

Doea anybody have .config file for EP8260 that I can use?
