Works for me. I'm using SDRAM in MS0 for code, stack, and data. Note that you'll need a recent interim release as earlier version of the libraries had some self-modifying code and the address computations assumed internal PM memory. Address computations for external PM memory work differently. You'll also need to initialize the SDRAM controller before using SDRAM, ie. in your boot loader. |
