1.7 wiki 11: # Installation
1.23 skrll 12: - You may use the rpi.img file created by an evbarm build - evbarm-earmv6hf is recommended.
1.34 wiki 13: - The Raspberry Pi port will be part of the NetBSD 7 release.
14: - 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/).
15: - The stable build will be under netbsd-7/YYYYMMDDHHMMZ/evbarm-earmv6hf/binary/gzimg/
1.23 skrll 16: - The HEAD/current build will be under HEAD/YYYYMMDDHHMMZ/evbarm-earmv6hf/binary/gzimg/
17: - For example, http://nyftp.netbsd.org/pub/NetBSD-daily/netbsd-7/201412161700Z/evbarm-earmv6hf/binary/gzimg/
1.19 wiki 18: - 'releasedir/evbarm/binary/gzimg/' if you run (for example) './build.sh -m evbarm -a earmv6hf -u release'

1.14 wiki 21: dd if=rpi.img of=/dev/disk1
22:
23: - Using a serial console
1.19 wiki 24: - By default the rpi.img is set to use the HDMI output; to change to using a serial console first mount rpi.img (it's a FAT filesystem)
1.14 wiki 25:

27:
1.10 wiki 28: - Growing the root file-system
1.17 wiki 29: - During the partitioning process, do not delete or format the
30: first MSDOS (FAT) partition, as the Raspberry pi firmware is
31: hard coded to boot on the SDCAD / 1st MSDOS partition / Firmware
32: updates and boot loader.
1.10 wiki 33: - Copy /boot/cmdline.txt to /boot/cmdline.txt.orig
1.15 wiki 34: - Edit /boot/cmdline.txt and add the '-s' flag to the end of the first line of text to boot into single-user mode.

49: Start offset prompt, press return to use the current value.
50: Partition size prompt, type "$" and press return to grow the
51: partition to use all available free space.
1.19 wiki 52:
1.15 wiki 53: - partition> prompt type "W" to save the changes to the disklabel.
1.11 wiki 54:
55: Confirm this choice by typing "y" at the Label disk prompt.
1.12 wiki 56: Type "Q" and press return to quit disklabel.
1.19 wiki 57:
1.15 wiki 58: - At the # prompt (shell), type
1.11 wiki 59:
60: fsck -fy /dev/rld0a

1.16 wiki 73: # Installation with sshramdisk image
74: - You may use the rpi_inst.img.gz file created by an evbarm build.
75: - Connect Ethernet Cable to RPI.
1.19 wiki 76: - After starting DHCP client, SSH login to with user "sysinst", and password "netbsd".
1.17 wiki 77: - Be careful to note the ip address given during DHCP so you don't lose your connection
78: - Also for after the sysinst is done and the system reboots
79: - sysinst started!

1.32 wiki 113: ## RetroArch / Libretro
114: 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:
115:
116: - Install [emulators/retroarch](http://pkgsrc.se/emulators/retroarch)
117: - 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).
118: - Plug in a USB HID compatible Gamepad, such as the Logitech F710 in "DirectInput" mode (set "D/X" switch to "D").
119: - Create a config file for your gamepad using *retroarch-joyconfig*.
120: [[!template id=programlisting text="""
1.35 ! wiki 121: $ retroarch-joyconfig -o gamepad.cfg
1.32 wiki 122: """]]
123: - Launch the emulator from the command-line (no X required):
124: [[!template id=programlisting text="""
125: $ retroarch --appendconfig gamepad.cfg -L /usr/pkg/lib/libretro/gambatte_libretro.so game.gbc
