Tool/software: Linux
Hello,
I am currently using the AM389x series, and I have memory related questions.
We used 8 DDR2 (x16 / 256MB) and connected all CS0 / CS1 to use 2GB of physical memory board.
However, we recently learned that the AM389x series does not guarantee functionality for CS1.
So we are considering two ways to use the CS0 to operate the board.
The first is to use 4 DDR2 (x16 / 256MB) and connect only CS0 to use 1GB of physical memory. In this regard, I want to use 256MB for the kernel and 768MB for the user area.
I'd like to know if this is possible.
The second method is to use 8 DDR2 (x8 / 256MB) and connect only CS0 to use 2GB of physical memory like existing board.
In the second method, since the data bandwidth of DDR2 is small, we are worried about the performance degradation between CPU operations.
Best Regards,
