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:
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.

18: - multi-user boot with root on SD card
19: - serial or graphics console (with EDID query / parsing)
20: - DMA controller driver and sdhc(4) support
21: - Audio: works. man page missing.
22: - I²C: works, could use enhancements, man page
23: - GPIO
24: - RNG
25: - SPI: could use enhancements, man page
26: - GPU (VCHIQ) - 3D and video decode. man page missing.
27: - USB (host) - dwctwo(4)
28: - USB Ethernet - usmsc(4)
29: - X windows.
30:
31: ## NetBSD 7 after July, 2017 and NetBSD 8
32:
33: - Raspberry Pi 3 (excluding WiFi and bluetooth)
34:
35: ## NetBSD current
36:
37: - Raspberry Pi 3 bluetooth
38: - Raspberry Pi 3 new SD host controller driver
39:
1.54 gdt 40: ## What needs work
1.53 gdt 41:
42: - USB (host); isochronous transfers.
43: - WiFi
44:
1.57 gdt 45: # CPU types
46:
47: Note that one can also use code for earlier models on later models.
48:
1.59 gdt 49: - Raspberry Pi 1 uses "earmv6hf".
50: - Raspberry Pi 2 uses "earmv7hf".
51: - Raspberry Pi 3 uses "earmv7hf". (NetBSD does not yet have 64-bit support.)
1.57 gdt 52:
1.7 wiki 53: # Installation
1.53 gdt 54:
1.58 gdt 55: First, decide if you want to install a formal release (7.1), a stable
56: branch build (netbsd-7, netbsd-8), or current. Note that 7.1 predates
57: Raspberry Pi 3 support. For people who don't know how to choose among
58: those, netbsd-8 is probably best.
59:
60: ## Getting bits to install
61:
62: You can either build a release yourself with build.sh, or get one from the NetBSD FTP servers.
63:
64: Both will provide rpi.img.gz and rpi_inst.img.gz. Each is an image to
65: be written to a uSD card, and it has a FAT32 partition for booting and
66: an FFS partition for NetBSD.
67:
68: ### Building yourself
69:
70: Getting sources and building a release with build.sh is not special for evbarm.
71: Pick a CPU type alias and pass it to build.sh with -m. Examples:
1.59 gdt 72: - ./build.sh -m earmv6hf -u release
73: - ./build.sh -m evbarm -a earmv6hf -u release
74: - ./build.sh -m evbarm -a earmv7hf -u release
1.58 gdt 75:
76: ### NetBSD FTP servers
77:
78: NetBSD provides nightly builds on [nyftp.netbsd.org](http://nyftp.netbsd.org/pub/NetBSD-daily/). These are equivalent to building yourself.
79:
1.59 gdt 80: - The 'evbarm-earmv6hf/binary/gzimg/' directory contains an rpi.img file that can be used as a single image for both boards.
81: - The 'evbarm-earmv7hf/binary/gzimg/' directory contains an armv7.img file that is optimized for Raspberry Pi 2.
82: - The stable build directory will be under netbsd-7/YYYYMMDDHHMMZ/ (for example, http://nyftp.netbsd.org/pub/NetBSD-daily/netbsd-7/201710201440Z/evbarm-earmv6hf/binary/gzimg)
83: - The not-yet-released stable build directory will be under netbsd-8/YYYYMMDDHHMMZ/ (for example, http://nyftp.netbsd.org/pub/NetBSD-daily/netbsd-8/201710211010Z/evbarm-earmv6hf/binary/gzimg/)
84: - The HEAD/current directory build will be under HEAD/YYYYMMDDHHMMZ/ (for example, http://nyftp.netbsd.org/pub/NetBSD-daily/HEAD/201710202210Z/evbarm-earmv7hf/binary/gzimg/)
1.58 gdt 85:
86: ## Installing to uSD
1.10 wiki 87:
1.61 ! gdt 88: Once you have rpi.img.gz, put it on a uSD card using gunzip and dd, for example:
1.14 wiki 89:
1.60 gdt 90: - gunzip rpi.img.gz
91: - dd if=rpi.i7mg of=/dev/disk1
1.14 wiki 92:
1.58 gdt 93: ### Serial Console
94:
95: By default the rpi.img is set to use the HDMI output. If you wish to use a serial console, first mount the FAT32 partition and then
96: edit cmdline.txt and remove '"console=fb"'.
1.14 wiki 97:
1.60 gdt 98: - 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 99:
1.60 gdt 100: In Kermit, the command is "set flow none".
1.41 wiki 101:
1.60 gdt 102: In minicom, run "minicom -s" and set hardware flow control to "no"
1.41 wiki 103:
1.58 gdt 104: ### Installation with sshramdisk image
105:
106: build.sh (and hence the FTP site) also creates an image 'rpi_inst.img.gz' specifically for installation without HDMI or a serial console. To use this method, write that image to a uSD card as above, and then:
1.53 gdt 107:
1.61 ! gdt 108: - Ensure that you have a lan with a DHCP server.
! 109: - Connect an Ethernet cable from the RPI to the LAN.
1.19 wiki 110: - After starting DHCP client, SSH login to with user "sysinst", and password "netbsd".
1.17 wiki 111: - Be careful to note the ip address given during DHCP so you don't lose your connection
112: - Also for after the sysinst is done and the system reboots
113: - sysinst started!
1.16 wiki 114:
1.55 gdt 115: ## Installation via ebijun's image
116:
1.58 gdt 117: As an alternative to the standard installation images, Jun Ebihara
118: provides an install image for Raspberry Pi that includes packages. It
119: is based on NetBSD-current and is built for earmv6hf, and thus will
120: work on Raspberry Pi 1, 2 and 3. This image is typically updated
121: every few weeks.
1.55 gdt 122:
1.56 gdt 123: - [https://github.com/ebijun/NetBSD/blob/master/RPI/RPIimage/Image/README](https://github.com/ebijun/NetBSD/blob/master/RPI/RPIimage/Image/README)
1.55 gdt 124:
1.53 gdt 125: ## Updating the kernel
1.46 schmonz 126:
1.42 wiki 127: - Build a new kernel, e.g. using build.sh. It will tell you where the ELF version of the kernel is, e.g.
128:
129: ...
130: Kernels built from RPI2:
131: /Users/feyrer/work/NetBSD/cvs/src-current/obj.evbarm-Darwin-XXX/sys/arch/evbarm/compile/RPI2/netbsd
132: ...
133:
1.47 sevan 134: - 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 135: - 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 136: - reboot
137:
1.24 wiki 138: # Wireless Networking
1.53 gdt 139:
140: Note that the built-in WiFi in the RPI3 is not yet supported.
141:
1.24 wiki 142: - A Realtek 802.11n USB adaptor configures as urtwn(4).
1.25 wiki 143: - Configure with wpa_supplicant in /etc/rc.conf -
1.24 wiki 144:
145: ifconfig_urtwn0=dhcp
146: dhcpcd=YES
147: dhcpcd_flags="-q -b"
148: wpa_supplicant=YES
149: wpa_supplicant_flags="-B -i urtwn0 -c /etc/wpa_supplicant.conf"
1.25 wiki 150: - A sample wpa_supplicant.conf can be found at /usr/share/examples/wpa_supplicant/wpa_supplicant.conf

153:
154: ## Video playback
1.29 wiki 155: 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 156:
157: ## OpenGL ES
158: 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.
159:
1.28 wiki 160: ## Quake 3
1.27 wiki 161: 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:
162:
163: - pak0.pk3 from Quake 3 CD
1.31 snj 164: - additional pak files from the [games/ioquake3-pk3](http://pkgsrc.se/games/ioquake3-pk3) package
1.27 wiki 165: - read/write permissions on /dev/vchiq and /dev/wsmouse
166:
1.31 snj 167: Place the pak0.pk3 file in the /usr/pkg/lib/ioquake3/baseq3 directory.
1.27 wiki 168:
1.32 wiki 169: ## RetroArch / Libretro
170: 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:
171:
172: - Install [emulators/retroarch](http://pkgsrc.se/emulators/retroarch)
173: - 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).
174: - Plug in a USB HID compatible Gamepad, such as the Logitech F710 in "DirectInput" mode (set "D/X" switch to "D").
175: - Create a config file for your gamepad using *retroarch-joyconfig*.
176: [[!template id=programlisting text="""
1.35 wiki 177: $ retroarch-joyconfig -o gamepad.cfg
1.32 wiki 178: """]]
179: - Launch the emulator from the command-line (no X required):
180: [[!template id=programlisting text="""
181: $ retroarch --appendconfig gamepad.cfg -L /usr/pkg/lib/libretro/gambatte_libretro.so game.gbc
182: """]]

1.53 gdt 184: # Developer notes
1.50 gdt 185:
1.53 gdt 186: These notes are for people working on improvements to RPI support in NetBSD.
1.50 gdt 187:
1.53 gdt 188: ## Updating the firmware
1.50 gdt 189:
1.53 gdt 190: You probably don't want to do this. Firmware updates can break things,
191: and the latest firmware that's been tested is already included in the
192: NetBSD build you installed.
1.50 gdt 193:
1.53 gdt 194: If you're feeling adventurous (or are the port maintainer), here's what
195: to test whenever you try new firmware:
1.50 gdt 196:
1.53 gdt 197: - Audio
198: - OMXPlayer (and [[!template id=man name="vchiq"]])
199: - Serial/framebuffer console
200: - CPU frequency scaling
1.50 gdt 201:
1.53 gdt 202: That goes for all of `rpi[0123]`.
1.1 jakllsch 203:
1.53 gdt 204: Upstream firmware releases are
205: [on GitHub](https://github.com/raspberrypi/firmware/releases).
206: Copy all files except `kernel*.img` into `/boot` and reboot.
