I suppose you could do this, but remember that you need to record
program counter samples as well and that the overhead of pushing data
out through an i/o channel is likely to be much greater than updating
it in the embedded systems memory. This may bias the results to such
an extent that makes them useless.
If you've got enough memory in your target system, I'd collect the data
locally, and then dump it to a desktop after the profile data has been
collected.
