I developed a board based on BF518F16 with 64Mbyte SDRAM and 8Gbyte NAND.
All work fine, but would like to know where can I find a document or an example code where explained the cache initialization and usage.
I use the GNU toolchain with a homebuilt environment:
In a simple SDRAM speed test I achieve a performance of 170 Mbyte/s in writing and 30 Mbyte/s in reading.
Can be these value increased with a correct cache initialization?
