I see from this thread:

...that some people were working on running writing custom images which get deployed via mfgtool of imx_usb_loader, for experimenting with various aspects of the system.
Did anyone ever get one of these doing anything at all interesting, and if so, is the source available? For example: drawing something on to the screen, although I'd be happy enough just making the LED blink.
I know I can also go and start dissecting u-boot, but it would save time if someone had already done one.
