[ECOS] Protecting RedBoot in the field

[Andrew Lunn]

Hi Folks

The devices we send out into the field still have redboot installed on
them. We are thinking this is a bit dangerous. Anyone can connect to
the serial port and hijack the devices, download tetris, destroy the
flash etc.

I don't want to remove the functionality of redboot. Its useful for
getting dead devices back to life and we do all our development work
with redboot starting the system. I don't like the idea of change to a
ROMRAM application.

Putting a password login onto the console seems the obvious
solution. Does anyone have any other ideas or other solutions they are
already using?

        Thanks
                Andrew
