RAM in Code memory area

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 Zova,

A easier way to do this is to enable the TCM during startup code, and program the coprocessor register for TCM configuration, and then copy the required program code into the I-TCM before entering main. However, this might not be possible in some boards with fixed firmware / OS.

Have you look at the TRM?
