Hi I am using Phytec Modul 165 with external RAM of 256k and Flash of 256k as well. Now uVision 2 configure only 16k of nData/nData1. That is when I define a structure array, it encouters an error of "exceeds nDATA/nDTAT0 limits: acc 23k max 16k. It happen when I do struct stdata buffer[300]; If I give 200 instead of 300, it is then fine. No error.The structure contains 37 bytes. So I want that uVision 2 knows that I have external RAM of 256k not just 16k so that all my data can be store into RAM for a while.
Select a different memory model, one that assumes variables are far or huge.
