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:
1.50 ! gdt 5: Initial, limited, 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. Raspberry Pi 3 support was added for NetBSD 8, and backported to NetBSD 7 in July of 2017.

1.7 wiki 13: # Installation
1.49 gdt 14: - The automatic nightly builds on [nyftp.netbsd.org](http://nyftp.netbsd.org/pub/NetBSD-daily/) provide image files that can be used for installation. The Raspberry Pi and Pi 2 ports are part of the NetBSD 7 release.
1.44 wiki 15: - The 'evbarm-earmv6hf/binary/gzimg/' directory contains an rpi.img file that can be used as a single image for both boards.
16: - The 'evbarm-earmv7hf/binary/gzimg/' directory, as of August 6th 2015, contains an armv7.img file that is optimized for Raspberry Pi 2.
17: - The stable build directory will be under netbsd-7/YYYYMMDDHHMMZ/ (for example, http://nyftp.netbsd.org/pub/NetBSD-daily/netbsd-7/201412161700Z/evbarm-earmv6hf/binary/gzimg/)
18: - The HEAD/current directory build will be under HEAD/YYYYMMDDHHMMZ/ (for example, http://nyftp.netbsd.org/pub/NetBSD-daily/netbsd-7/201508062150Z/evbarm-earmv7hf/binary/gzimg/)
19: - You can build your own version of these images using (for example) './build.sh -m evbarm -a earmv6hf -u release', or './build.sh -m evbarm -a earmv7hf -u release'
20: - <i>gunzip and dd</i> this img to your sd card. For example,
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:
1.47 sevan 29: - 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".
1.41 wiki 30:
31: In Kermit, the command is "set flow none".
32:
33: In minicom, run "minicom -s" and set hardware flow control to "no"
34:
1.44 wiki 35: - Growing the root file-system (**not required with NetBSD -current after 2015-04-07, or by NetBSD 7 after 2015-08-06**)
1.17 wiki 36: - During the partitioning process, do not delete or format the
37: first MSDOS (FAT) partition, as the Raspberry pi firmware is
38: hard coded to boot on the SDCAD / 1st MSDOS partition / Firmware
39: updates and boot loader.
1.10 wiki 40: - Copy /boot/cmdline.txt to /boot/cmdline.txt.orig
1.15 wiki 41: - 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 42: - For the next steps, the root filesystem mustn't be mounted rw. So reboot, and at the prompt to enter the pathname of shell,
43: press return for the default (/bin/sh).
1.10 wiki 44: - At the # prompt, type
45:
46: "disklabel -i ld0" and press return.
1.19 wiki 47:
1.15 wiki 48: - At the partition> prompt type "A" and press return.
1.10 wiki 49:
50: Adjust disklabel sector from 4194304 to 62333952 [n]?
51: Type "y" and press return.
1.19 wiki 52:
1.15 wiki 53: - partition> prompt type "a" and press return.
1.12 wiki 54:
1.11 wiki 55: Filesystem type prompt, press return to use the current value (4.2BSD).
56: Start offset prompt, press return to use the current value.
57: Partition size prompt, type "$" and press return to grow the
58: partition to use all available free space.
1.19 wiki 59:
1.15 wiki 60: - partition> prompt type "W" to save the changes to the disklabel.
1.11 wiki 61:
62: Confirm this choice by typing "y" at the Label disk prompt.
1.12 wiki 63: Type "Q" and press return to quit disklabel.
1.19 wiki 64:
1.15 wiki 65: - At the # prompt (shell), type
1.11 wiki 66:
67: fsck -fy /dev/rld0a
68: resize_ffs -y /dev/rld0a
1.19 wiki 69:
1.11 wiki 70: - This may take a few minutes, be patient!
71:
72: fsck -fy /dev/rld0a
1.18 wiki 73: mount_msdos /dev/ld0e /boot
1.11 wiki 74: mv /boot/cmdline.txt.orig /boot/cmdline.txt
75: reboot
1.19 wiki 76:
1.11 wiki 77: - When the system comes back up, the root file-system will have been expanded to
1.10 wiki 78: fill the SD card.
1.7 wiki 79:
1.16 wiki 80: # Installation with sshramdisk image
81: - You may use the rpi_inst.img.gz file created by an evbarm build.
82: - Connect Ethernet Cable to RPI.
1.19 wiki 83: - After starting DHCP client, SSH login to with user "sysinst", and password "netbsd".
1.17 wiki 84: - Be careful to note the ip address given during DHCP so you don't lose your connection
85: - Also for after the sysinst is done and the system reboots
86: - sysinst started!
1.16 wiki 87:
1.7 wiki 88: # Updating the firmware
1.45 schmonz 89:
90: You probably don't want to do this. Firmware updates can break things,
91: and the latest firmware that's been tested is already included in the
92: NetBSD build you installed.
93:
94: If you're feeling adventurous (or are the port maintainer), here's what
95: to test whenever you try new firmware:
96:
97: - Audio
98: - OMXPlayer (and [[!template id=man name="vchiq"]])
99: - Serial/framebuffer console
100: - CPU frequency scaling
101:
1.46 schmonz 102: That goes for all of `rpi[0123]`.
103:
1.45 schmonz 104: Upstream firmware releases are
105: [on GitHub](https://github.com/raspberrypi/firmware/releases).
106: Copy all files except `kernel*.img` into `/boot` and reboot.
1.7 wiki 107:
1.42 wiki 108: # Updating the kernel
109: - Build a new kernel, e.g. using build.sh. It will tell you where the ELF version of the kernel is, e.g.
110:
111: ...
112: Kernels built from RPI2:
113: /Users/feyrer/work/NetBSD/cvs/src-current/obj.evbarm-Darwin-XXX/sys/arch/evbarm/compile/RPI2/netbsd
114: ...
115:
1.47 sevan 116: - Besides the "netbsd" kernel in ELF format, there is also a "netbsd.bin" kernel that is in a format that the Raspberry can boot.
1.48 sevan 117: - Depending on your hardware version, copy this either to /boot/kernel.img (First generation Pi, Pi Zero hardware) or to /boot/kernel7.img (Pi 2, Pi 3 hardware)
1.42 wiki 118: - reboot
119:
1.24 wiki 120: # Wireless Networking
121: - A Realtek 802.11n USB adaptor configures as urtwn(4).
1.25 wiki 122: - Configure with wpa_supplicant in /etc/rc.conf -
1.24 wiki 123:
124: ifconfig_urtwn0=dhcp
125: dhcpcd=YES
126: dhcpcd_flags="-q -b"
127: wpa_supplicant=YES
128: wpa_supplicant_flags="-B -i urtwn0 -c /etc/wpa_supplicant.conf"
1.25 wiki 129: - A sample wpa_supplicant.conf can be found at /usr/share/examples/wpa_supplicant/wpa_supplicant.conf
1.24 wiki 130:
1.27 wiki 131: # GPU

133: ## Video playback
1.29 wiki 134: Accelerated video playback is supported in NetBSD 7 with the [OMXPlayer](http://pkgsrc.se/multimedia/omxplayer) application and through GStreamer with the [omx](http://pkgsrc.se/multimedia/gst-plugins1-omx) plugin.
1.27 wiki 135:
136: ## OpenGL ES
137: Accelerated OpenGL ES is supported in NetBSD 7. The GL ES client libraries are included with the [misc/raspberrypi-userland](http://pkgsrc.se/misc/raspberrypi-userland) package.
138:
1.28 wiki 139: ## Quake 3
1.27 wiki 140: A Raspberry Pi optimized build of *ioquake3* is available in the [games/ioquake3-raspberrypi](http://pkgsrc.se/games/ioquake3-raspberrypi) package. To use it, the following additional resources are required:
141:
142: - pak0.pk3 from Quake 3 CD
1.31 snj 143: - additional pak files from the [games/ioquake3-pk3](http://pkgsrc.se/games/ioquake3-pk3) package
1.27 wiki 144: - read/write permissions on /dev/vchiq and /dev/wsmouse

1.32 wiki 148: ## RetroArch / Libretro
149: 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:
150:
151: - Install [emulators/retroarch](http://pkgsrc.se/emulators/retroarch)
152: - 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).
153: - Plug in a USB HID compatible Gamepad, such as the Logitech F710 in "DirectInput" mode (set "D/X" switch to "D").
154: - Create a config file for your gamepad using *retroarch-joyconfig*.
155: [[!template id=programlisting text="""
1.35 wiki 156: $ retroarch-joyconfig -o gamepad.cfg
1.32 wiki 157: """]]
158: - Launch the emulator from the command-line (no X required):
159: [[!template id=programlisting text="""
160: $ retroarch --appendconfig gamepad.cfg -L /usr/pkg/lib/libretro/gambatte_libretro.so game.gbc
