I seem to have fried TX on my TTL serial converter. I can't get a new
one until Tuesday. I'll see if I can rig things up to boot without
needing to type since I can still receive the serial output.

I was using this modified for tftp loading. But I was setting fdt high
after loading the dtb, not before. Does that make a difference? FDT
has to be working or it would have errored out earlier when the
machine name didn't match.

env set fdt_high ffffffff
ext2load mmc 0 0x46000000 uImage.new
ext2load mmc 0 0x49000000 dtb
setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p3 ro rootwait loglevel=5
bootm 0x46000000 - 0x49000000

you can use tftp like this so that you don't have to keep rewriting the sd card.

env set fdt_high ffffffff
tftp 0x46000000 /server/uImage.new
tftp 0x49000000 /server/dtb
setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p3 ro rootwait loglevel=5
bootm 0x46000000 - 0x49000000

You can completely eliminate the SD card by NFS mounting the rootfs
root=/dev/nfs rw nfsroot=12.345.67.89:/path/on/server/to/nfs_root ip=dhcp

So recompile and hit reset. No need to write SD Card. Everything works
really fast over the GbE.

Now if only CT had a quick reset button.... simpler just to add a
switch in the power supply line.
