You will need some type of "execute in place", i.e. run the kernel and/or userspace applications out of ROM in order to work with 2MB of RAM. This type of thing is generally very board, processor and application specific. So I don't believe there is existing (open source) code to do it. --Mark ** Sent via the linuxppc-embedded mail list.
