RTOS/TMS320F28335: Minimizing RAM resources required for DSP/BIOS

Part Number: TMS320F28335

Tool/software: TI-RTOS

Hello,

I'm trying to minimize the RAM resources required by DSP/BIOS 5.42.02.10

My TCF is:

utils.loadPlatform("ti.platforms.ezdsp28335");

/* The following DSP/BIOS Features are enabled.  */
bios.enableTskManager(prog);

// !GRAPHICAL_CONFIG_TOOL_SCRIPT_INSERT_POINT!

prog.gen();

So currently there are no DSP/BIOS objects at all.

The map file is:

DSP/BIOS takes ~15% from the RAM.

Is it possible to make it smaller ?

Thank you,

Zvika

That's it for the .tcf? When things are not configured in the .tcf, they still have defaults. If you open the .tcf graphically, you can see the defaults. What size is the heap? Do you need a heap? What are the sizes of your stacks (both system and task)? Look can look in CCS's ROV (or KOV...depending on your CCS version) to see the peaks of the stacks.

Hi Todd,

I opened the tcf with the configuration tool.

According to the tool, for L03SARAM, L47SARAM, MSARAM, "create a heap in this memory = False", heap size=0x200

Does it mean that heap is consuming resources ?

If yes, how can I change it ?

Thank you,

Zvika

If the setting is "False" for the "create a heap in this memory", there is no heap.
