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.
13: - The Raspberry Pi port will be part of the NetBSD 7 stable release,
14: but you may want to use the HEAD branch for the latest development code.
15: - The automatic nightly builds can be found in the 'evbarm-earmv6hf/binary/gzimg/' directory under on [nyftp.netbsd.org](http://nyftp.netbsd.org/pub/NetBSD-daily/).
16: - The HEAD/current build will be under HEAD/YYYYMMDDHHMMZ/evbarm-earmv6hf/binary/gzimg/
17: - The stable build will be under netbsd-7/YYYYMMDDHHMMZ/evbarm-earmv6hf/binary/gzimg/
18: - For example, http://nyftp.netbsd.org/pub/NetBSD-daily/netbsd-7/201412161700Z/evbarm-earmv6hf/binary/gzimg/
1.19 wiki 19: - 'releasedir/evbarm/binary/gzimg/' if you run (for example) './build.sh -m evbarm -a earmv6hf -u release'
1.23 skrll 20: - <i>gunzip and dd</i> this img to your sd card.
1.10 wiki 21:
1.14 wiki 22: dd if=rpi.img of=/dev/disk1
23:
24: - Using a serial console
1.19 wiki 25: - 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 26:
27: edit cmdline.txt and remove '"console=fb"'
28:
1.10 wiki 29: - Growing the root file-system
1.17 wiki 30: - During the partitioning process, do not delete or format the
31: first MSDOS (FAT) partition, as the Raspberry pi firmware is
32: hard coded to boot on the SDCAD / 1st MSDOS partition / Firmware
33: updates and boot loader.
1.10 wiki 34: - Copy /boot/cmdline.txt to /boot/cmdline.txt.orig
1.15 wiki 35: - Edit /boot/cmdline.txt and add the '-s' flag to the end of the first line of text to boot into single-user mode.
1.20 wiki 36: - For the next steps, the root filesystem mustn't be mounted rw. So reboot, and at the prompt to enter the pathname of shell,
37: press return for the default (/bin/sh).

39:
40: "disklabel -i ld0" and press return.

45: Type "y" and press return.
1.19 wiki 46:
1.15 wiki 47: - partition> prompt type "a" and press return.
1.12 wiki 48:
1.11 wiki 49: Filesystem type prompt, press return to use the current value (4.2BSD).
50: Start offset prompt, press return to use the current value.
51: Partition size prompt, type "$" and press return to grow the
52: partition to use all available free space.
1.19 wiki 53:
1.15 wiki 54: - partition> prompt type "W" to save the changes to the disklabel.
1.11 wiki 55:
56: Confirm this choice by typing "y" at the Label disk prompt.
1.12 wiki 57: Type "Q" and press return to quit disklabel.
1.19 wiki 58:
1.15 wiki 59: - At the # prompt (shell), type
1.11 wiki 60:
61: fsck -fy /dev/rld0a
62: resize_ffs -y /dev/rld0a
1.19 wiki 63:
1.11 wiki 64: - This may take a few minutes, be patient!
65:
66: fsck -fy /dev/rld0a
1.18 wiki 67: mount_msdos /dev/ld0e /boot
1.11 wiki 68: mv /boot/cmdline.txt.orig /boot/cmdline.txt
69: reboot
1.19 wiki 70:
1.11 wiki 71: - When the system comes back up, the root file-system will have been expanded to
1.10 wiki 72: fill the SD card.
1.7 wiki 73:
1.16 wiki 74: # Installation with sshramdisk image
75: - You may use the rpi_inst.img.gz file created by an evbarm build.
76: - Connect Ethernet Cable to RPI.
1.19 wiki 77: - After starting DHCP client, SSH login to with user "sysinst", and password "netbsd".
1.17 wiki 78: - Be careful to note the ip address given during DHCP so you don't lose your connection
79: - Also for after the sysinst is done and the system reboots
80: - sysinst started!

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