Hi all,

I keep seeing comments such as "you need to run menuconfig". But nobody ever gives the exact command line or which directory is supposed to be current when it is issued. I believe (no real basis, just other build systems) the line is 'make menuconfig' but that requires a Makefile and issuing it on the Makefiles I have found so far does not work - 'No Target of that name' or similar errors. Searching on the Wiki yields no hits.

So, precisely, how does one reconfigure the kernel and rootfs?

Does the Linux kernel that ships with Overo Earth include support for

problem, or a cable problem...

As shipped, the musb (OTG) port is configured for host only.  If you
want the ethernet gadget you will need to modify the kernel config for
either device or OTG mode and rebuild.

So, what's with the connector labeled "Host", then?  I'm confused...

The OMAP3 processors have 2 USB ports:

1. musb: will operate in device, OTG, or host mode via kernel config
2. ehci: host mode only.  this interface isn't currently functional
with the linux-omap kernel top of tree.

As delivered the musb driver is configured for host only.  You would
need to run menuconfig and select either device or OTG if you want to
use the ethernet gadget (and rebuild the kernel of course).
