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.

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

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:
1.58 gdt 88: Once you have rpi.img.gz, put it on a uSD card using gunzip and dd, for examples
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:
1.16 wiki 108: - Connect Ethernet Cable to RPI.
1.19 wiki 109: - After starting DHCP client, SSH login to with user "sysinst", and password "netbsd".
1.17 wiki 110: - Be careful to note the ip address given during DHCP so you don't lose your connection
111: - Also for after the sysinst is done and the system reboots
112: - sysinst started!
1.16 wiki 113:
1.55 gdt 114: ## Installation via ebijun's image
115:
1.58 gdt 116: As an alternative to the standard installation images, Jun Ebihara
117: provides an install image for Raspberry Pi that includes packages. It
118: is based on NetBSD-current and is built for earmv6hf, and thus will
119: work on Raspberry Pi 1, 2 and 3. This image is typically updated
120: every few weeks.
1.55 gdt 121:
1.56 gdt 122: - [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 123:
1.53 gdt 124: ## Updating the kernel
1.46 schmonz 125:
1.42 wiki 126: - Build a new kernel, e.g. using build.sh. It will tell you where the ELF version of the kernel is, e.g.
127:
128: ...
129: Kernels built from RPI2:
130: /Users/feyrer/work/NetBSD/cvs/src-current/obj.evbarm-Darwin-XXX/sys/arch/evbarm/compile/RPI2/netbsd
131: ...
132:
1.47 sevan 133: - 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 134: - 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 135: - reboot
136:
1.24 wiki 137: # Wireless Networking
1.53 gdt 138:
139: Note that the built-in WiFi in the RPI3 is not yet supported.
140:
1.24 wiki 141: - A Realtek 802.11n USB adaptor configures as urtwn(4).
1.25 wiki 142: - Configure with wpa_supplicant in /etc/rc.conf -
1.24 wiki 143:
144: ifconfig_urtwn0=dhcp
145: dhcpcd=YES
146: dhcpcd_flags="-q -b"
147: wpa_supplicant=YES
148: wpa_supplicant_flags="-B -i urtwn0 -c /etc/wpa_supplicant.conf"
1.25 wiki 149: - A sample wpa_supplicant.conf can be found at /usr/share/examples/wpa_supplicant/wpa_supplicant.conf

152:
153: ## Video playback
1.29 wiki 154: 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 155:
156: ## OpenGL ES
157: 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.
158:
1.28 wiki 159: ## Quake 3
1.27 wiki 160: 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:
161:
162: - pak0.pk3 from Quake 3 CD
1.31 snj 163: - additional pak files from the [games/ioquake3-pk3](http://pkgsrc.se/games/ioquake3-pk3) package
1.27 wiki 164: - read/write permissions on /dev/vchiq and /dev/wsmouse
165:
1.31 snj 166: Place the pak0.pk3 file in the /usr/pkg/lib/ioquake3/baseq3 directory.
1.27 wiki 167:
1.32 wiki 168: ## RetroArch / Libretro
169: 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:
170:
171: - Install [emulators/retroarch](http://pkgsrc.se/emulators/retroarch)
172: - 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).
173: - Plug in a USB HID compatible Gamepad, such as the Logitech F710 in "DirectInput" mode (set "D/X" switch to "D").
174: - Create a config file for your gamepad using *retroarch-joyconfig*.
175: [[!template id=programlisting text="""
1.35 wiki 176: $ retroarch-joyconfig -o gamepad.cfg
1.32 wiki 177: """]]
178: - Launch the emulator from the command-line (no X required):
179: [[!template id=programlisting text="""
180: $ retroarch --appendconfig gamepad.cfg -L /usr/pkg/lib/libretro/gambatte_libretro.so game.gbc
181: """]]

1.53 gdt 183: # Developer notes
1.50 gdt 184:
1.53 gdt 185: These notes are for people working on improvements to RPI support in NetBSD.
1.50 gdt 186:
1.53 gdt 187: ## Updating the firmware
1.50 gdt 188:
1.53 gdt 189: You probably don't want to do this. Firmware updates can break things,
190: and the latest firmware that's been tested is already included in the
191: NetBSD build you installed.
1.50 gdt 192:
1.53 gdt 193: If you're feeling adventurous (or are the port maintainer), here's what
194: to test whenever you try new firmware:
1.50 gdt 195:
1.53 gdt 196: - Audio
197: - OMXPlayer (and [[!template id=man name="vchiq"]])
198: - Serial/framebuffer console
199: - CPU frequency scaling
1.50 gdt 200:
1.53 gdt 201: That goes for all of `rpi[0123]`.
1.1 jakllsch 202:
1.53 gdt 203: Upstream firmware releases are
204: [on GitHub](https://github.com/raspberrypi/firmware/releases).
205: Copy all files except `kernel*.img` into `/boot` and reboot.
