Thanks Paul,
I'm trying to flash my GSM firmware and running into a problem.
I get to the point where I run the fluid command line and it just  
sits there.

Here are the steps I'm taking for doing the flashing. I'm following  
the docs on the wiki
at:
http://wiki.openmoko.org/wiki/GSM/Flashing.

After I get the
Bootloader: (reset target)
message, I run "s3c24xx-gpio b7=1" in another xterm, ssh'ed into the FR.

and the main window just sits there.

Here's the output of what I'm typing in the main window:

Help ?
How long should I wait for the Bootloader to respond to the "s3c24xx- 
gpio b7=1" command ?
The documentation makes it sound like it should happen right away.

Thanks,
