Let's say it's an odd day and `bitbake omap3-console-image` works without a hiccup and you want to put it on an SDHC card.

Here's a script that will partition the card no matter what the size (does the math for you). It can be run on the gumstix itself or on the host system with a card reader:

You'll have to reboot the gumstix (or remove and reinsert the SDHC card) for the kernel to register the changes
Then you can install the image like so (also from the gumstix or host system)

Of course, once you copy either script to a file you must `chmod a+x` it.

I've been using these for myself and thought I'd share.
