Execute the Code from RAM in ARM Processors

[swapgo]

Hi All,

I find some sort of dificulty in running the code in RAM for ARM Processor.

I use LPC2106 and the compiler is Keil uVision 3 Evaluation software.

I did the following set up in the Keil uVision IDE.

In the Location " Options -> LA Locate -> User Classes " I added ERAM(0x40000000-0x40000FFF).

Then I added __ram for my function to make it to run from ram.

" void switch1()__ram ".

While linking a microsoft error reporting window opens and the linking fails as a result I will not get the .hex file.

Why it is happening so? Is it because I use a evaluation software.

Or is there is any other Options to be enabled?

Or will it suit only for a processor with external memory?

Any one with sucess histroy of using __ram option in CRAM? Please let me know.

Thanks and Regards
Gopi Pemmasani
