Build and flash instructions

Building the firmware


  • SDCC
  • Binutils (needs objcopy)

On Ubuntu this can be installed with:

sudo apt-get install sdcc binutils

On Mac (using homebrew):

brew install sdcc
brew install binutils
ln -s /usr/local/bin/gobjcopy /usr/local/bin/objcopy

To build the firmware you should navigate to the firmware directory.

Flashing the Firmware

To flash the firmware run the following from the firmware directory:

sudo python ../usbtools/ flash bin/cradio.bin

After flashing successfully, you need to replug the Crazyradio. More details are in the wiki.
