#OpenOCD simple flasher script to use with "make program". Version 0.3.
#It generates temporary command script to the openocd in openocd.flash file, then runs openocd.
#This script requires proper openocd.cfg file in the invokation path.
#It converts elf file to bin format. Path to the *.elf file can be passed as an argument (eg. ../ )
#Any comments are welcome. CeDeROM 2008 ( http://www.tomek.cedro.info )
