RAM in Code memory area

Woody Wu
Note: This was originally posted on 20th June 2011 at http://forums.arm.com

Hi,

My board has 32K SRAM in the code memory area (within the first 0.5G), also has the same size of build in SRAM in data area.  My question is, what kind of data are suitable to put in CODE area?  Particularly, should I set the main stack in CODE SRAM or DATA SRAM?

Thanks in advance.

    Hi narke, may I ask how you access the I/D SRAM or say I/DTCM ? Have you modified your linker program? Now, I'm facing the same problem as you. I want to put some code in code SRAM (my board is S3C6410, ARM1176JZF-S based), but I've no idea about how to place code in.

    Thanks,
