Question: Error: " Cannot allocate system memory - out of memory " 

Answer: This is caused by the DOS 640K system memory limitation. You can solve this problem by trying to maximize the available memory in the following ways:

• Get a simulator upgrade: TI has incorporated a memory cache approach that implements a virtual memory system based on the space available in your disk.
• Use the Microsoft Windows version of the simulator.
• Remove device drivers as you can from your autoexec.bat file.
• Modify your siminit.cmd file declaring only the memory ranges needed in your application.
