I believe that you can set the baud rate on the kernel command passed
in from u-boot. You'll need to edit the /etc/inittab file to change
the baud rate that getty initializes as well, and you'll probably want
to change the baud rate that u-boot uses as well.

Hi I just installed openbedded basic image for connex.. great.. very
impressed.

However usbnet isn't working for me..

If I start the usb0 interface either with ifup, or by adding an auto
entry to /etc/init.d/interfaces , it comes up at the default static
address, and my pc (ubuntu 7.10, uses usbnet sucessfully with buildroot
gumstix) detects it, bringing up its own usb0 interface, which I can
configure as before, however it just doesnt work- pings are not replied.

However if I manually remove and restart the g_ether module on the
gumstix, and restart the usb0 interface, it works perfectly as before, i
can ping and ssh in.

Would seem to be some weird timing thing with the startup sequence? 

Has anyone had success with usbnet on oe?

Tim

Hi I don't know whether anyone else uses usbnet on oe,

however:

as configured it doesnt work (just for me?) - although the interface
initialises and thinks its ok.

if i add these lines to the relevant section
of /etc/network/interfaces/ 

pre-up /sbin/modprobe g_ether;/sbin/modprobe
gumstix_gadget                  	
post-down /sbin/modprobe -r g_ether

:: similar to the way it used to have to be configured for buildroot::

now, it works, but only the SECOND time the interface is initialised!
(either through an auto enty or manually via ifup).

This, unfortuneately is no use- I need to take away the console board.

can anyone think of a reason why the usbnet gadget would only work the
SECOND time it is initialised?

OK I have managed to get usbnet to work by the clumsy expedient of
stopping and starting it a second time in the start stanza
of /etc/init.d/networking...

I'm using USBnet on a connex 200xm without any problems. I originally
connected via serial and then started the interface manually using
ifconfig usb0 192.168.0.2
To have the gumstix set up the interface each time it boots, edit the
/etc/network/interfaces file, replace "iface usb0 inet dhcp" with

iface usb0 inet static
address 192.168.0.2
netmask 255.255.255.0

then on the host load the appopriate kernel module (it's called usbnet
on Arch Linux) and then connect with ifconfig usb0 192.168.0.1
That works perfectly for me, though I'm yet to flash the root
filesystem with a new version and see if still works....
