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:
5: Initial 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.

1.7 wiki 13: # Installation
1.36 wiki 14: - You may use the rpi.img file created by an evbarm build - evbarm-earmv6hf is recommended. This isn't optimized for Raspberry Pi 2, but allows a single image to be used for all boards.
1.38 wiki 15: - The Raspberry Pi and Pi 2 ports will be part of the NetBSD 7 release.
1.34 wiki 16: - 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/).
17: - The stable build will be under netbsd-7/YYYYMMDDHHMMZ/evbarm-earmv6hf/binary/gzimg/
1.23 skrll 18: - The HEAD/current build will be under HEAD/YYYYMMDDHHMMZ/evbarm-earmv6hf/binary/gzimg/
19: - For example, http://nyftp.netbsd.org/pub/NetBSD-daily/netbsd-7/201412161700Z/evbarm-earmv6hf/binary/gzimg/
1.19 wiki 20: - 'releasedir/evbarm/binary/gzimg/' if you run (for example) './build.sh -m evbarm -a earmv6hf -u release'
1.23 skrll 21: - <i>gunzip and dd</i> this img to your sd card.
1.10 wiki 22:
1.14 wiki 23: dd if=rpi.img of=/dev/disk1
24:
25: - Using a serial console
1.19 wiki 26: - 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 27:
28: edit cmdline.txt and remove '"console=fb"'
29:
1.41 wiki 30: - 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".
31:
32: In Kermit, the command is "set flow none".
33:
34: In minicom, run "minicom -s" and set hardware flow control to "no"
35:
1.40 wiki 36: - Growing the root file-system (**not required with NetBSD -current after 2015-04-07**)
1.17 wiki 37: - During the partitioning process, do not delete or format the
38: first MSDOS (FAT) partition, as the Raspberry pi firmware is
39: hard coded to boot on the SDCAD / 1st MSDOS partition / Firmware
40: updates and boot loader.
1.10 wiki 41: - Copy /boot/cmdline.txt to /boot/cmdline.txt.orig
1.15 wiki 42: - 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 43: - For the next steps, the root filesystem mustn't be mounted rw. So reboot, and at the prompt to enter the pathname of shell,
44: press return for the default (/bin/sh).
1.10 wiki 45: - At the # prompt, type
46:
47: "disklabel -i ld0" and press return.
1.19 wiki 48:
1.15 wiki 49: - At the partition> prompt type "A" and press return.
1.10 wiki 50:
51: Adjust disklabel sector from 4194304 to 62333952 [n]?
52: Type "y" and press return.
1.19 wiki 53:
1.15 wiki 54: - partition> prompt type "a" and press return.
1.12 wiki 55:
1.11 wiki 56: Filesystem type prompt, press return to use the current value (4.2BSD).
57: Start offset prompt, press return to use the current value.
58: Partition size prompt, type "$" and press return to grow the
59: partition to use all available free space.
1.19 wiki 60:
1.15 wiki 61: - partition> prompt type "W" to save the changes to the disklabel.
1.11 wiki 62:
63: Confirm this choice by typing "y" at the Label disk prompt.
1.12 wiki 64: Type "Q" and press return to quit disklabel.
1.19 wiki 65:
1.15 wiki 66: - At the # prompt (shell), type
1.11 wiki 67:
68: fsck -fy /dev/rld0a
69: resize_ffs -y /dev/rld0a
1.19 wiki 70:
1.11 wiki 71: - This may take a few minutes, be patient!
72:
73: fsck -fy /dev/rld0a
1.18 wiki 74: mount_msdos /dev/ld0e /boot
1.11 wiki 75: mv /boot/cmdline.txt.orig /boot/cmdline.txt
76: reboot
1.19 wiki 77:
1.11 wiki 78: - When the system comes back up, the root file-system will have been expanded to
1.10 wiki 79: fill the SD card.
1.7 wiki 80:
1.16 wiki 81: # Installation with sshramdisk image
82: - You may use the rpi_inst.img.gz file created by an evbarm build.
83: - Connect Ethernet Cable to RPI.
1.19 wiki 84: - After starting DHCP client, SSH login to with user "sysinst", and password "netbsd".
1.17 wiki 85: - Be careful to note the ip address given during DHCP so you don't lose your connection
86: - Also for after the sysinst is done and the system reboots
87: - sysinst started!
1.16 wiki 88:
1.7 wiki 89: # Updating the firmware
1.8 wiki 90: - [rpi firmware files](https://github.com/raspberrypi/firmware/tree/master/boot)
1.19 wiki 91: - Copy all files except 'kernel*.img' into /boot and reboot
1.7 wiki 92:
1.42 ! wiki 93: # Updating the kernel
! 94: - Build a new kernel, e.g. using build.sh. It will tell you where the ELF version of the kernel is, e.g.
! 95:
! 96: ...
! 97: Kernels built from RPI2:
! 98: /Users/feyrer/work/NetBSD/cvs/src-current/obj.evbarm-Darwin-XXX/sys/arch/evbarm/compile/RPI2/netbsd
! 99: ...
! 100:
! 101: - Besides the "netbsd" kernel in ELF format, there is also a "netbsd.bin" kernel that is in a format that the Raspberry can boot.
! 102: - Depending on your hardware version, copy this either to /boot/kernel.img (old/V1 hardware) or to /boot/kernel7.img (new/V2 hardware)
! 103: - reboot
! 104:

1.32 wiki 133: ## RetroArch / Libretro
134: 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:
135:
136: - Install [emulators/retroarch](http://pkgsrc.se/emulators/retroarch)
137: - 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).
138: - Plug in a USB HID compatible Gamepad, such as the Logitech F710 in "DirectInput" mode (set "D/X" switch to "D").
139: - Create a config file for your gamepad using *retroarch-joyconfig*.
140: [[!template id=programlisting text="""
1.35 wiki 141: $ retroarch-joyconfig -o gamepad.cfg
1.32 wiki 142: """]]
143: - Launch the emulator from the command-line (no X required):
144: [[!template id=programlisting text="""
