The output on the serial console goes like this on power up.

== Executing boot script in 1.000 seconds - enter ^C to abort

At this point, hit Control-C to interrupt the boot loader[4]. This will
give you the RedBoot prompt. Enter the following commands:

> load -v -r -b 0x01800000 -m ymodem ramdisk.gz
> load -v -r -b 0x01008000 -m ymodem zImage
> exec -c "console=ttyS0,115200 rw root=/dev/ram mem=256M at 0xa0000000" -r
0x01800000
