Status of USB TTY support in u-boot

Jason's tree : http://www.beagleboard.org/gitweb/?p=u-boot-arm.git;a=shortlog;h=try-musb-20090201

Jason pointed me to suggestions from dirk on IRC, I had missed reading it.

The TTY support works on this tree, it fails when we type reset.

Dirk - thanks.

Khasim,

I developed most of the code and I can give you a hand if you need.
I'm just a bit buried by several customers (which is a good thing, I
guess :S ), so I take a bit to respond.

The sakoman tree has code in the config file to set the environment to
USBTTY and serial (both at the same time), is just that if the board
has pre-defined environment for std* the config definitions doesn't
matter, so you have to change them manually.

Hangs very frequently.

Sakoman's tree:
http://www.sakoman.net/cgi-bin/gitweb.cgi?p=u-boot-omap3.git;a=shortlog;h=refs/heads/omap3-dev-usb

Doesn't seem to work, the input, output and err are directed to Serial
(and not to USBTTY).

Thanks Jason! :slight_smile:

We re-started omap3-dev-usb from scratch after mainline merge of basic OMAP3 code. If the config option was lost while doing this, sorry. I didn't check with old omap3-dev-usb tree. If anybody likes to change this in omap3-dev-usb board config files, a patch would be nice.

The TTY support works on this tree, it fails when we type reset.

Please check the mail I will sent in some minutes...

Best regards

I was seeing it hang very frequently when I hit the reset button, but
not if I typed "reset". I haven't tried the latest version with the
CONFIG_MUSB_TIMEOUT change that Dirk sent out (I've been working at a
customer site this week).
