Checkout and compile Cleanflight

Head over to the Cleanflight Github page and grab the URL of the GIT Repository: "https://github.com/cleanflight/cleanflight.git"

Open the Cygwin-Terminal, navigate to your development folder and use the git commandline to checkout the repository:

cd /cygdrive/c/dev
git clone https://github.com/cleanflight/cleanflight.git

GIT Checkout

GIT Checkout

To compile your Cleanflight binaries, enter the cleanflight directory and build the project using the make command. You can append TARGET=[HARDWARE] if you want to build anything other than the default NAZE target:

cd cleanflight
make TARGET=NAZE

GIT Checkout

within few moments you should have your binary ready:

(...)
arm-none-eabi-size ./obj/main/cleanflight_NAZE.elf
   text    data     bss     dec     hex filename
  95388     308   10980  106676   1a0b4 ./obj/main/cleanflight_NAZE.elf
arm-none-eabi-objcopy -O ihex --set-start 0x8000000 obj/main/cleanflight_NAZE.elf obj/cleanflight_NAZE.hex

You can use the Cleanflight-Configurator to flash the obj/cleanflight_NAZE.hex file.
