Work in progress.

Your application needs memory tracing enabled. To enable this in your application:

1. Set a high serial baud rate to avoid a large slowdown in your application.

2. Add the visual memory tracer library to your project:

   $ mbed add https://github.com/janjongboom/mbed-visual-memory-tracer-lib
   

3. Enable the following macros in your mbed_app.json:

   {
       "macros": [
           "MBED_MEM_TRACING_ENABLED",
           "MBED_HEAP_STATS_ENABLED=1"
       ]
   }

4. Initialize the tracer library by placing initialization code in both mbed_main and main:

   #include "mbed.h"
   #include "mbed_vis_mem_tracer.h"
   
   extern "C" void mbed_main() {
       mbed_vismem_preinit();
   }
   
   int main() {
       mbed_vismem_init();
   
       // ... rest of your application
   }

Preferably use a separate UART port for the trace information.

Set your serial port and baud rate in tracer.js, then run:

1. npm install
2. node tracer.js

To get the symbols from your application, run arm-none-eabi-objdump -S path/to/your.elf. Will automate this in the future.
