   This page attempts to document and coordinate efforts towards NetBSD/evbarm on [Raspberry Pi](http://www.raspberrypi.org). All board variants are supported.
   
   Initial Raspberry Pi support was introduced in NetBSD 6.0. NetBSD 7.0 adds complete support for the board, along with introducing support for the quad-core Raspberry Pi 2 board.

  - Growing the root file-system     - Most (all?) USB-to-TTL serial adapters only connect Tx, Rx and ground, and do not connect any flow control lines. An effect of missing flow control is that you see console output, but cannot type anything. If so, adjust your serial console application's flow control settings to "none". 
   
         In Kermit, the command is "set flow none".
   
         In minicom, run "minicom -s" and set hardware flow control to "no"

   ## RetroArch / Libretro
   Using [emulators/retroarch](http://pkgsrc.se/emulators/retroarch) it is possible to run many emulators at full speed the Raspberry Pi. Emulator cores for various gaming consoles are available in the [emulators/libretro-*](http://pkgsrc.se/search.php?so=libretro-) packages. To begin using retroarch:
   
 # Additional links   - Install [emulators/retroarch](http://pkgsrc.se/emulators/retroarch)
  - [ARM userland utilities](https://github.com/jaredmcneill/userland)   - Install the libretro core for the system you would like to emulate (lets take [emulators/libretro-gambatte](http://pkgsrc.se/emulators/libretro-gambatte), a GameBoy Color emulator, as an example).
    - Plug in a USB HID compatible Gamepad, such as the Logitech F710 in "DirectInput" mode (set "D/X" switch to "D").
    - Create a config file for your gamepad using *retroarch-joyconfig*.
   [[!template  id=programlisting text="""
   $ retroarch-joyconfig -o gamepad.cfg
   """]]
    - Launch the emulator from the command-line (no X required):
   [[!template  id=programlisting text="""
   $ retroarch --appendconfig gamepad.cfg -L /usr/pkg/lib/libretro/gambatte_libretro.so game.gbc
