Yeah, you should be able to boot without issues. If you don't flash, I think the overo is pretty brick-proof.

Good luck, it sounds like you may have a hardware issue.

G'day Blaine,

As far as I know, I did not flash the overo, I just attempted to boot it
up from the sdcard. Assuming that the attempt to boot hasn't affected
the NAND, that means that I have other problems.....

Currently, the overo goes through the entire boot sequence, up until it
asks for me to login. At this point, it displays the JFFS2 notice from
my original email, and the overo hangs, with no response shown in the
kermit terminal despite my typing "root" and then enter.

I did put a finger on top of the overo, and noted that it is pretty hot,
as is the 10/100 port on the Tobi itself. I am thinking that I have a
power issue, so I'll try to get that sorted in the next day or so and
see if that fixes anything.

Of course, if you have any other ideas, feel free to suggest them and
I'll see what I can do.
