Did I understand this right: you'd only have the Lua
_scripts_ (precompiled bytecode) in the banked memory?
How much of scripts do you have?
That would mean no banking is used for the GC'able
objects. Makes no sense to me..

Can you share a few more details?
The banking is in external RAM.
We have sufficient code space as the microcontroller is
addressing 16MB of it - (Harvard architecture so
separate address and
It's main limitation is on data space, since it can only
address 64KB of
ram for which 32KB is on chip for application variable
storage, 16KB is
used for constant data access and the remaining 16KB
would be for page
access to the external 1MB of data ram that would only
be used to hold
the Lua scripts.
