I can log into Angstrom via DVI monitor and USB hub, and the Angstrom
install seems fine.
Serial Angstrom login:
beagleboard login: ¹oot
òïïô@båagìåbïaòdºþ# oot
I've tried putty and teraterm with the same results. I managed to get
it to work once, but I have not been able to repeat. I haven't been
able to find anything on this site or any others about serial working
until Angstrom logs in, so any assistance would be greatly
appreciated.
Serial settings:
115200
8 bits
1 stop
parity: none
flow ctrl: none

That's a 'feature' of the omap cpuidle code: http://www.elinux.org/OMAP_Power_Management
The uart goes to sleep after 5 seconds and will loose some bits on wakeup.

I tried Angstrom-Beagleboard-demo-image-glibc-ipk-2009.X-
stable-20090612--beagleboard.rootfs.tar.bz2 and it starts out with the
same problem. Max, what do you mean by reset command? "Reset
terminal" in putty just clears the screen, and I can't type "reset,"
as only the s shows up. If I do a system reboot using the reset
button, then the serial terminal seems to work fine. At least it has
twice in a row now. Thanks!

I have always had trouble with screen and the beagleboard console on
my machine, this applies to every angstrom kernel .32 I have used so
far, downloaded or self compiled ;-)
Every now and then the output from the beagleboard freezes, but
characters sent to the beagleboard seem to be transmitted fine for a
while after the freeze. If I restart screen, the output resumes as
normal. This is a minor issue for me, but annoying nontheless.
On the newest demo image, the problem is a bit worse:
I feel the frequency of freezes is greater, and when I write (or
sometimes on the login prompt/ascii graphic) transmitted characters
appear garbled (lots of funny characters and ??). In many cases I can
type characters and communication will resume as normal after a while
- other times it is impossible for me to write anything more unless
performing a reset with the reset button on the board or powering it
down.
cheers,
