Well there's 128K of PROM and 4K of RAM in the ATMEGA 128
and I believe it is all available. At the end of the TOS
compile you get a line that says how much your program is
using. If you are not doing any kind of dynamic allocation
this should be the maximum used. Perhaps you have a pointer
or something that is running amuck in a way that you don't
see in simulation.
I think using FLASH is rather slow and the number of MTBF
cycles is not conducive to temporary storage.

I did other experiments and i found that, with little data size, the nodes are
able to send and receive all packets they generate. So it's definitely a memory
problem. But i think not to use so much memory and i free, when i can, the used
structures. Remember i need a buffer chain in each node cause i store incoming
packets and then i create new coded packets from these buffers.
Now my question is: with Micaz motes, tinyos 1.x, how much memory in ROM and
RAM can i use?
and is it possible to use the FLASH memory?if yes how?and what's the size of it?
If possible, i'd like to receive very precise informations for understanding
my problem in the best way.
Thanks very much for your availability
cheers

Sounds like your buffering scheme is overflowing and crashing the mote.
One clue is that I seem to see a lot of length 5 buffer pools in TOS...
You might want to double check that you are freeing buffers after use.
