BOOTIE, A RUDIMENTARY BOOTLOADER FOR COMPUTATIONAL RFIDS
Author: Ben Ransford <ransford@cs.umass.edu>, April 2010

QUICK START:
 1. Put your standalone programs (i.e., programs that have their own main()
    functions) in the firmwares/ subdirectory.
 2. Install LLVM, Clang, and mspgcc4 following the instructions at
    https://github.com/ransford/mementos/wiki/Building-and-installing.
 3. cd llvm
    ./configure
    make
    make install # may require root
    cd ..
 4. ./configure
    make
 5. You will see an MSP430 ELF executable called 'bootloader'.

This version of Bootie simply rotates among firmware images on successive boots
of the device.  The included programs a.c and b.c (in firmwares/) serve as
examples.  For now, input programs like a.c and b.c are not allowed to contain
interrupt handlers or share function names (except main(), which will be
renamed at build time).

To use programs other than firmwares/a.c and b.c, make your own subdirectory,
e.g. myfirmwares/, and run 'make FWDIR=myfirmwares' in step 4 above.
