To hack b2g on the RPi, you'll want to set up a few things. First, a serial console is strongly recommended. (A serial console is basically required for kernel development.) You can purchase a serial-to-USB or serial-port connector for your RPi, [https://www.adafruit.com/products/954 for example this one from adafruit]. Some RPi kits also include one of these. A common serial-to-USB The adapter included in RPi kits shown above requires you to connect the black lead to pin 6 (ground), the white lead to pin 8 (GPIO14, UART0_TXD), and the green lead to pin 10 (GPIO15, UART0_RXD). You don't need to connect the red lead if your RPi already has a power source.  <font size="5" color="red">'''WARNING'''</font>: be very careful that you connect the leads to the correct pins! At least one developer has burned out a USB-to-serial adapter by connecting the wrong pins. The b2g kernel is pre-configured to open a serial console for the RPi, so all you need to do is plug the USB cable into your host machine and start up a terminal emulator. The <code>minicom</code> program works well. On ubuntu, install minicom with the command
