Usage of external DDR memory

[SathishRaja]

Hi,

We are using MPC5645s controller in our project, with that we are using 64 MB external DDR memory.

We are utilizing only 8 MB to display image.

We want to utilize more of the DDR memory instead of internal RAM by allocating global data and heap section.

Can you give us some example code or way to use external RAM to its full capacity.

Hi,

I have simple project which shows how to create a segment in linker file and how to place some data to the segment. See main.c file and linker file MPC5644B.lcf.
