RE: [ECOS] Mmu and Memory Layout

[honda at itri dot org dot tw]

Hello,

     What's the main difference in  the MMU configuration and Memory Layout
between the 1.3.1 and the current version. Version 1.3.1 did work on
EDB7212, it hang on the MMU_INITIALIZE. But when I modified it for my own
system, it didn't work. By upgrade to the current version, it works. Why?

=============================================================================
Since you're starting fresh - please don't use 1.3.1 - it's way too
old and we won't be able to help you much.  Start from the current
anonymous CVS.

Other than that, you have the basic grasp of what needs to be done.
