Trying to set the IDE to recognize additional RAM available from a larger external DDRAM designed into current design

Larry Shilkoff

I'm currently trying to upgrade the DDRAM externally addressed by a SAM9G15 processor from a 2Meg part to a 4Meg part. The code is being developed on a Keil uVision IDE (vesion 5.14.0.0) and I have been trying to get the development system to recognize that there is additional DDRAM available. The options menu, under "Target", has an option to adjust the RAM1 size, which I changed from 0x200000 to 0x400000. With this change I continue to get error messages about exceeding memory limits. I also tweeked the scatter file (CG_SAM9.sct) to reflect different memory allocation without success. Is there anything else I may need to do to support increased memory availabliity?
