9: # Installation
10: - You may use the rpi.img file created by an evbarm build - evbarm-earmv6hf is recommended.
11: - The Raspberry Pi port will be part of the NetBSD 7 stable release,
12: but you may want to use the HEAD branch for the latest development code.
13: - 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/).
14: - The HEAD/current build will be under HEAD/YYYYMMDDHHMMZ/evbarm-earmv6hf/binary/gzimg/
15: - The stable build will be under netbsd-7/YYYYMMDDHHMMZ/evbarm-earmv6hf/binary/gzimg/
16: - For example, http://nyftp.netbsd.org/pub/NetBSD-daily/netbsd-7/201412161700Z/evbarm-earmv6hf/binary/gzimg/
17: - 'releasedir/evbarm/binary/gzimg/' if you run (for example) './build.sh -m evbarm -a earmv6hf -u release'
18: - <i>gunzip and dd</i> this img to your sd card.
20: dd if=rpi.img of=/dev/disk1
22: - Using a serial console
23: - 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)
25: edit cmdline.txt and remove '"console=fb"'
27: - Growing the root file-system
28: - During the partitioning process, do not delete or format the
29: first MSDOS (FAT) partition, as the Raspberry pi firmware is
30: hard coded to boot on the SDCAD / 1st MSDOS partition / Firmware
31: updates and boot loader.
32: - Copy /boot/cmdline.txt to /boot/cmdline.txt.orig
33: - Edit /boot/cmdline.txt and add the '-s' flag to the end of the first line of text to boot into single-user mode.
34: - For the next steps, the root filesystem mustn't be mounted rw. So reboot, and at the prompt to enter the pathname of shell,
35: press return for the default (/bin/sh).
36: - At the # prompt, type
38: "disklabel -i ld0" and press return.
40: - At the partition> prompt type "A" and press return.
42: Adjust disklabel sector from 4194304 to 62333952 [n]?
43: Type "y" and press return.
45: - partition> prompt type "a" and press return.
47: Filesystem type prompt, press return to use the current value (4.2BSD).
48: Start offset prompt, press return to use the current value.
49: Partition size prompt, type "$" and press return to grow the
50: partition to use all available free space.
52: - partition> prompt type "W" to save the changes to the disklabel.
54: Confirm this choice by typing "y" at the Label disk prompt.
55: Type "Q" and press return to quit disklabel.
57: - At the # prompt (shell), type
59: fsck -fy /dev/rld0a
60: resize_ffs -y /dev/rld0a
62: - This may take a few minutes, be patient!
64: fsck -fy /dev/rld0a
65: mount_msdos /dev/ld0e /boot
66: mv /boot/cmdline.txt.orig /boot/cmdline.txt
69: - When the system comes back up, the root file-system will have been expanded to
70: fill the SD card.
72: # Installation with sshramdisk image
73: - You may use the rpi_inst.img.gz file created by an evbarm build.
74: - Connect Ethernet Cable to RPI.
75: - After starting DHCP client, SSH login to with user "sysinst", and password "netbsd".
76: - Be careful to note the ip address given during DHCP so you don't lose your connection
77: - Also for after the sysinst is done and the system reboots
78: - sysinst started!
80: # Updating the firmware
81: - [rpi firmware files](https://github.com/raspberrypi/firmware/tree/master/boot)
82: - Copy all files except 'kernel*.img' into /boot and reboot
84: # Wireless Networking
85: - A Realtek 802.11n USB adaptor configures as urtwn(4).
86: - Configured with wpa_supplicant in /etc/rc.conf -
90: dhcpcd_flags="-q -b"
92: wpa_supplicant_flags="-B -i urtwn0 -c /etc/wpa_supplicant.conf"
95: # Additional links
96: - [ARM userland utilities](https://github.com/jaredmcneill/userland)
98: # What works in -current
99: - multi-user boot with root on SD card
100: - serial or graphics console (with EDID query / parsing)
101: - DMA controller driver and sdhc(4) support
102: - Audio: works. man page missing.
103: - I²C: works, could use enhancements, man page
104: - GPIO
105: - RNG
106: - SPI: could use enhancements, man page
107: - VCHIQ: man page missing.
108: - USB (host) - dwctwo(4)
109: - USB Ethernet - usmsc(4)
110: - X windows.
112: # What needs work
113: - USB (host); isochronous transfers.
