From where getTotalHeap and getFreeHeap come?
What works is malloc_stats(), it prints directly:
max system bytes = 43896
system bytes = 43896
in use bytes = 40008
Also the following structure from malloc.h:All of these are showing only to the used heap, including fragments.
Probably the rest can be safely assumed/calculated from linker info, without forcing malloc.
Usually, the stacks stay bounded in the other SRAM banks (SCRATCH).

Code:
/* This version of struct mallinfo must match the one in libc/stdlib/mallocr.c. */struct mallinfo { size_t arena; /* total space allocated from system */ size_t ordblks; /* number of non-inuse chunks */ size_t smblks; /* unused -- always zero */ size_t hblks; /* number of mmapped regions */ size_t hblkhd; /* total space in mmapped regions */ size_t usmblks; /* unused -- always zero */ size_t fsmblks; /* unused -- always zero */ size_t uordblks; /* total allocated space */ size_t fordblks; /* total non-inuse space */ size_t keepcost; /* top-most, releasable (via malloc_trim) space */};Probably the rest can be safely assumed/calculated from linker info, without forcing malloc.
