+====== OTA (Over The Air) update of the STM32 using the Crazyradio/Crazyradio PA ======
+The Crazyflie and Crazyflie 2.0 has the possibility to be updated/flashed over the air using the Crazyradio or Crazyradio PA. This will cover how to do it using the make util.
+== Prerequisite ==
+   * A Crazyflie or Crazyflie 2.0
+   * A Crazyradio or Crazyradio PA
+   * The [[projects:crazyflie:pc_utils:install|PC client]] installed and working
+   * The [[https://github.com/bitcraze/crazyflie-firmware|Crazyflie]] or [[https://github.com/bitcraze/crazyflie-firmware/tree/crazyflie2|Crazyflie 2.0]] source code
+(This has been tested on ubuntu but should work on mac and windows with the necessary tools installed)
+== Instructions ==
+For it to work out of the box the crazyflie-clients-python and the crazyflie-firmware needs to be located in the same directory. If it isn't the cfloader path can be altered in the Crazyflie Makefile
+<code>
+CLOAD_SCRIPT      ?= ../crazyflie-clients-python/bin/cfloader
+</code>
+Then go into the crazyflie-firmware directory and compile the firmware. The firmware should be compiled with CLOAD=1 (default). If it is the compilation output will say "CrazyLoader build!" in the end.
+<code>
+cf@bitcraze:~/projects/crazyflie-firmware$ make -j4
+...
+  LD    cflie.elf
+  COPY  cflie.hex
+  COPY  cflie.bin
+   text	   data	    bss	    dec	    hex	filename
+	   1112	  26892	 101996	  18e6c	cflie.elf
+Build g05f2a3b3a726:05f2a3b3a726 (2014.01.0-15) MODIFIED
+CrazyLoader build!
+rm version.c
+</code>
+When the code has been compiled without any errors it is time to put the crazyflie on bootloader mode.
+|| Crazyflie | Crazyflie 2.0 ||
+|| Power it on after lanching the script | When turning it on hold the button until the blue led starts to blink ||
+To lanch the firmware update run "make cload"
+<code>
+cf@bitcraze:~/projects/crazyflie-firmware$ make cload
+../crazyflie-clients-python/bin/cfloader flash cflie.bin stm32-fw
