  -p, --program         Program file
  -v, --verify          Verify by file

The order of the above options matters! The table is ordered by normal
execution order. For the options "Epv" a file must be specified.
Program flow specifiers default to "pvr" if a file is given.
Don't forget to specify "e" or "eE" when programming flash!

Data retreiving:
  -u, --upload=addr     Upload a datablock (see also: -s).
  -s, --size=num        Size of the data block do upload. (Default is 2)
  -x, --hex             Show a hexadecimal display of the uploaded data.
                        (Default)
  -b, --bin             Get binary uploaded data. This can be used
                        to redirect the output into a file.

Do before exit:
  -g, --go=address      Start programm execution at specified address.
                        This implies option --wait.
  -r, --reset           Reset connected MSP430. Starts application.
                        This is a normal device reset and will start
                        the programm that is specified in the reset
                        vector. (see also -g)
  -w, --wait            Wait for <ENTER> before closing serial port.

If it says "NAK received" it's probably because you specified no or a
wrong password.
