Trace heap allocation

Norbert Toth

I'm using CCS6 for application development on Tiva4C Connected Launchpad. The programming language is C++ (so new calls malloc). Under the project options I enabled the heap so every dynamic memory allocation is redirected to "malloc" and "free" provided by TI runtime library.

How can I trace the pointer of the newly allocated memory (and maybe its size)? Is there any JTAG debugger option or defining some hook or whatever else...

Norbert,

Without a RTOS, there are no pre-built mechanisms to track heap usage either from the JTAG, the debugger or the compiler options. However, this subject was discussed in the past and a few threads may help:

e2e.ti.com/.../1628326

(this last one has links to other discussions)
Hope this helps,
Rafael

Hi,

Yes, I know this form of tracing and I already found the entry point of it, but the problem is that I'm using C++ as mentioned and the STL containers (string, map, vector, etc) as well and they bypass the FreeRTOS memory managers and calls "operator new" directly.

Norbert

Norbert,

Apart from filling the memory and visually inspecting it via a memory browser (similar to what is mentioned in the thread below), unfortunately there is no mechanism for dynamically checking the heap usage. Sorry.
