Customer is working on the PPC ADS8260 reference design.
They need to support up to 512MB RAM based on the
ADS design.
-Is it possible to support this?
(There seems to be 64MB block available at the start of
memory, but then there is a block dedicated to
a different type of memory, so it seems as if the
memory map will have to change radically.)
-How difficult is this (to change the memory map)?
-Does anyone have any detailed info on the implementation
of this, pointers, issues etc?
-I’m assuming that the main system RAM has to contiguous
both for this hardware as well as QNX. Is this correct?
If the board supports this then yes. With the BSP for this board you
can change the code so that it supports it. By default it only supports
16MB of RAM (this is coded), but with the BSP you will have the souce
code to change this to whatever the board can see.

Thanks.
Motorola subsequently told the customer that the board
only supports up to 128 MB with 2x64MB organisation.
