5: This page attempts to document and coordinate efforts towards NetBSD/evbarm on [Raspberry Pi](http://www.raspberrypi.org).

9: # Installation
10: - Use the latest HEAD/-current which builds for install
11: - As the raspberry pi port is still not part the stable release, you will want to use the
12: HEAD branch to download installation sets.
13: - You may use the rpi.img file created by an arm build.
14: - An example can be found in the '/evbarm/binary/gzimg/' directory under releng.netbsd.org
15: - On nyftp.netbsd.org/pub/NetBSD-daily/HEAD/YYYYMMDDHHMMZ (it will look like pub/NetBSD-daily/HEAD/201305220150Z)
16: - 'obj/releasedir/evbarm/binary/gzimg/' if you run (for example) './build.sh -m evbarm -u release'
17: - <i>gunzip and dd</i> this img to your sd card.
19: dd if=rpi.img of=/dev/disk1
21: - Using a serial console
22: - By default the rpi.img is set to use the HDMI output; to change mount rpi.img (it's a FAT filesystem)
24: edit cmdline.txt and remove '"console=fb"'
25: - proceed with the 'dd'
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: - Reboot, and at the prompt to enter the passname of shell, press
35: return for the default (/bin/sh).
36: - At the # prompt, type
38: "disklabel -i ld0" and press return.
39: - At the partition> prompt type "A" and press return.
41: Adjust disklabel sector from 4194304 to 62333952 [n]?
42: Type "y" and press return.
43: - partition> prompt type "a" and press return.
45: Filesystem type prompt, press return to use the current value (4.2BSD).
46: Start offset prompt, press return to use the current value.
47: Partition size prompt, type "$" and press return to grow the
48: partition to use all available free space.
49: - partition> prompt type "W" to save the changes to the disklabel.
51: Confirm this choice by typing "y" at the Label disk prompt.
52: Type "Q" and press return to quit disklabel.
53: - At the # prompt (shell), type
55: fsck -fy /dev/rld0a
56: resize_ffs -y /dev/rld0a
57: - This may take a few minutes, be patient!
59: fsck -fy /dev/rld0a
60: mount_msdos /dev/ld0e /boot
61: mv /boot/cmdline.txt.orig /boot/cmdline.txt
63: - When the system comes back up, the root file-system will have been expanded to
64: fill the SD card.
66: # Installation with sshramdisk image
67: - You may use the rpi_inst.img.gz file created by an evbarm build.
68: - Connect Ethernet Cable to RPI.
69: - After starting DHCP client,SSH login to RPI with user "sysinst",passwd "netbsd".
70: - Be careful to note the ip address given during DHCP so you don't lose your connection
71: - Also for after the sysinst is done and the system reboots
72: - sysinst started!
74: # Updating the firmware
75: - [rpi firmware files](https://github.com/raspberrypi/firmware/tree/master/boot)
76: - Copy all files except 'kernel*img' into /boot and reboot
78: # Additional links
79: - [ARM userland utilities](https://github.com/jaredmcneill/userland)
81: # What works
82: - multi-user boot with root on SD card
83: - serial or graphics console (with EDID query / parsing)
84: - X windows.
85: - USB (host); control, interrupt and bulk transfers. Has some stability issues that are being worked on. man page missing.
86: - USB Ethernet
87: - RNG: works
88: - I²C: works, could use enhancements, man page
89: - SPI: works, could use enhancements, man page
90: - VCHIQ: work in progress. man page missing. (-current)
91: - Audio: works. man page missing. (-current)
93: # What needs work
94: - USB (host); isochronous transfers. DMA support.
95: - DMA controller driver / dmover(9) backend
96: - Teach sdhc(4) about dmover; not Raspberry Pi specific
97: - hardfloat; not Raspberry Pi specific
98: - earm ABI; not Raspberry Pi specific
99: - GPIO
