Hi ,

I'm doing data acquisition with the BF548.I use DMA to bring data from my SPORT peripheral to my External L3-RAM.I have Two x8 DDR RAM of 64MBytes each connected in parallel.Thing is i need to DMA large amount of data into external memory.

I want to know is it possible to declare a buffer large enough to contain 30Mbytes of data?How in the code can you declare such a buffer to tell the linker you want to put it in the external RAM?
