Locking flash memory

Is there a way to lock the flash memory in the beagle oars black?

What I want to do is to install Ubuntu in the flash then install software sans lock the flash. Any work done saved on an USB key the embedded flash untouched. Is there a way?


You can apply the method normally used in embedded platforms to partition the flash and store a squashfs ro image and use that to boot from. You will of course need to create tmpfs and any mounts for nonvolatile data which can be stored on a rw partition.

You would need to use mksquashfs to generate the image.
