 +====== Programming Crazyflie from firmware projects ====== 
 + 
 +When developping with the Crazyflie firmware projects, either [[https://github.com/bitcraze/crazyflie-firmware|crazyflie-firmware]] or [[https://github.com/bitcraze/crazyflie2-nrf-firmware|crazyflie2-nrf-firmware]] you can flash your current build with: 
 +<code> 
 +make cload 
 +</code> 
 + 
 +If you want the Crazyflie to restart automatically in bootloader mode you can enable the warmboot mode. To do so, edit the file 'tool/make/config.mk' and add the address of your Crazyflie: 
 +<code> 
 +CLOAD_CMDS = -w radio://0/80/250K/E7E7E7E7E7 
 +</code> 
 + 
 +After this, 'make cload' will restart the Crazyflie in bootlader mode, flash it and restart it with the new firmware. 
 + 
 + 
 +<WRAP center round info> 
 +In warmboot mode the bootloader is launched using a random address. This means that multiple Crazyflie can be programmed at the same time without collision.

 +//**Warning**// 
 +If the flashing operation fails or if the firmware has a bug, it may be impossible to warmbootIn that case start the bootloader manually and disable warmboot temporarly by programming with: 
 +<code> 
 +make cload CLOAD_CMDS=
