1. building the project
   
   a. add environment variable in ~/.bashrc

      export RTT_ROOT=/home/bright/smart-lock/RT-Thread
      export RTT_EXEC_PATH=/usr/local/gcc-arm-none-eabi-4_7-2013q1/bin
      export RTT_CC=gcc
      export RTT_BUILD=debug

   b. modify rtconfig.py for compile command and other variable

      PROJECT = 'smart_lock'      
      ARCH='arm'
      CPU='cortex-m3'
      
      EXEC_PATH = '/usr/local/gcc-arm-none-eabi-4_7-2013q1/bin'

   c. copy bsp/stm32f10x/* to your project root directory

      .

   d. compile the project for debug and release

   for debug:

   cd the project root directory
   run "scons" and "scons -j 4"

   for release:

   set environment variable RTT_BUILD=release
   cd the project root directory
   run "scons" and "scons -j 4"

   e. clean the project
   
   run "scons -c"

2. debug and program
   
   a. for program(jlink):

   install openocd for debug and enable jlink
   link jlink to the board
   cd the project root directory
   run "
   
   sudo /usr/local/bin/openocd -f yuettak_smart_lock_jlink.cfg 

   telnet localhost 4444
   {
	halt
	flash write_image erase $PROJECT.elf
	reset
   }

   "
   b. for program(openjtag):

   install openocd for debug and enable openjtag
   link openjtag to the board
   cd the project root directory
   run "
   
   sudo /usr/local/bin/openocd -f yuettak_smart_lock_openjtag.cfg

   telnet localhost 4444
   {
	newboot	
   }


   "

   b. for debug
   
   install openocd for debug and enable openjtag
   link openjtag to the board
   cd the project root directory
   run "
   
   sudo /usr/local/bin/openocd -f yuettak_smart_lock_openjtag.cfg

   telnet localhost 4444
   {
	newboot
   }
   open emacs and M-x gdb
   /home/bright/CodeSourcery/Sourcery_CodeBench_Lite_for_ARM_EABI/bin/arm-none-eabi-gdb -i=mi smart_lock.elf -x gdb.init

   gdb.init:
   {
	target remote localhost:3333
	monitor init
	monitor reset init
	monitor sleep 200 
	monitor flash probe 0 
	monitor sleep 200 
	load
	monitor reset halt
	monitor poll
	thbreak main 
	continue 
   }
