[Tinyos-devel] stack depth checking

[steve ayer]

hi all,

a former colleague (andy christian) here wrote one awhile back; don't 
know what's supported, but it works great with msp430 elf executables 
from the msp430-gcc toolchain.

it's in the old tinyos-1.x/contrib/handhelds tree, but i can check it 
into tos-2.x when i get a second if other think that it's useful.

for now, tinyos-1.x/contrib/handhelds/tools/scripts/memuse.py.
