Gumstix Overo Fire booting from microSD card

I’m happy to report that I managed to make my Gumstix Overo Fire boot from the microSD card! After a few failed attempts as I mentioned here, I noticed an error message in the boot sequence:

A Google search lead to this discussion suggesting to “clearing the environment in nand” with:

Now I have the Gumstix Overo Fire booting from the microSD and even the Ethernet on the Tobi board is working (it didn’t work with the factory image from 2009). I tried both the desktop and the console image and both seem to work. I am very impressed tby the fact that the console image only consumes 45 MB of RAM once it is booted, leaving almost 200 MB for applications.
