Hi TI,

After build wlan_station project, the CCS show memory allocation as below.

After the wlan_station project execute, how many memory remainder?

Is a 98304 - 48097? or less?

Looking at your screen capture it looks like the SRAM on the device has been divided into a block for CODE and a block for DATA. If you expand each one you will be able to see what is being placed in each.

The amount of the SRAM_DATA block remaining is 98304 - 48097. However the amount of SRAM_CODE remaining is 81920 - 66759. i.e. there is less memory available for code.

The linker command file defines the sizes of SRAM_CODE and SRAM_DATA.

Regards,
John

Hi John,

After CCS build this project, there is about (98304 - 48097) + (81920 - 66759) memory available for used.

This point that I know.

But I want to know how many memory remainder after project execute.

Ex: (98304 - 48097) + (81920 - 66759) - X = Y. I want to know Y.

The CCS can provide this information? or have other tool can provide?

thanks.

CCS doesn't provide much in the way of runtime memory analysis. If the project is using TI-RTOS then one feature that is available is the Runtime Object Viewer.

Using ROV you can track the runtime stack and heap usage. At the end of the video it shows how to open the stack graph, using the same sequence there is a heap graph there as well.

Some more information here:

Hi,

Quick comment...

Default linker file in wlan_station demo in CC3200 SDK does not use whole available RAM. It use only 176 of RAM. CC3200 chip have 256kB of RAM. By changing linker file you can use this unused RAM (up to 256kB - 16kB). Only first 16kB of RAM is limited to use.
