1.1 jakllsch 1: [[!meta title="NetBSD/evbarm on Raspberry Pi"]]
2:
1.39 wiki 3: This page attempts to document and coordinate efforts towards NetBSD/evbarm on [Raspberry Pi](http://www.raspberrypi.org). All board variants are supported.
4:
5: 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.

1.7 wiki 13: # Installation
1.36 wiki 14: - You may use the rpi.img file created by an evbarm build - evbarm-earmv6hf is recommended. This isn't optimized for Raspberry Pi 2, but allows a single image to be used for all boards.
1.38 wiki 15: - The Raspberry Pi and Pi 2 ports will be part of the NetBSD 7 release.
1.34 wiki 16: - The automatic nightly builds can be found in the 'evbarm-earmv6hf/binary/gzimg/' directory on [nyftp.netbsd.org](http://nyftp.netbsd.org/pub/NetBSD-daily/).
17: - The stable build will be under netbsd-7/YYYYMMDDHHMMZ/evbarm-earmv6hf/binary/gzimg/
1.23 skrll 18: - The HEAD/current build will be under HEAD/YYYYMMDDHHMMZ/evbarm-earmv6hf/binary/gzimg/
19: - For example, http://nyftp.netbsd.org/pub/NetBSD-daily/netbsd-7/201412161700Z/evbarm-earmv6hf/binary/gzimg/
1.19 wiki 20: - 'releasedir/evbarm/binary/gzimg/' if you run (for example) './build.sh -m evbarm -a earmv6hf -u release'

29:

34: updates and boot loader.
1.10 wiki 35: - Copy /boot/cmdline.txt to /boot/cmdline.txt.orig
1.15 wiki 36: - Edit /boot/cmdline.txt and add the '-s' flag to the end of the first line of text to boot into single-user mode.

53: partition to use all available free space.
1.19 wiki 54:
1.15 wiki 55: - partition> prompt type "W" to save the changes to the disklabel.
1.11 wiki 56:
57: Confirm this choice by typing "y" at the Label disk prompt.
1.12 wiki 58: Type "Q" and press return to quit disklabel.
1.19 wiki 59:

Emulator cores for various gaming consoles are available in the [emulators/libretro-*](http://pkgsrc.se/search.php?so=libretro-) packages. To begin using retroarch:
117:
118: - Install [emulators/retroarch](http://pkgsrc.se/emulators/retroarch)
119: - 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).
120: - Plug in a USB HID compatible Gamepad, such as the Logitech F710 in "DirectInput" mode (set "D/X" switch to "D").
121: - Create a config file for your gamepad using *retroarch-joyconfig*.
122: [[!template id=programlisting text="""
1.35 wiki 123: $ retroarch-joyconfig -o gamepad.cfg
1.32 wiki 124: """]]
125: - Launch the emulator from the command-line (no X required):
126: [[!template id=programlisting text="""
127: $ retroarch --appendconfig gamepad.cfg -L /usr/pkg/lib/libretro/gambatte_libretro.so game.gbc
