9: # Installation
10: - You may use the rpi.img file created by an arm build.
11: - An example can be found in the '/evbarm/binary/gzimg/' directory under releng.netbsd.org
12: - <i>gunzip and dd</i> this img to your sd card.
14: - Growing the root file-system
15: - Copy /boot/cmdline.txt to /boot/cmdline.txt.orig
16: - Edit /boot/cmdline.txt and add the '-s' flag to the end of the first line of text.
17: - Reboot, and at the prompt to enter the passname of shell, press
18: return for the default (/bin/sh).
19: - At the # prompt, type
21: "disklabel -i ld0" and press return.
22: - At the partition> prompt, type "A" and press return. You will see
23: a message like:
25: Adjust disklabel sector from 4194304 to 62333952 [n]?
26: Type "y" and press return.
27: - At the partition> prompt, type "a" and press return.
28: - At the Filesystem type prompt, press return to use the current value (4.2BSD).
29: - At the Start offset prompt, press return to use the current value.
30: - At the Partition size prompt, type "$" and press return to grow the
31: partition to use all available free space.
32: - At the partition> prompt, type "W" to save the changes to the
33: disklabel. Confirm this choice by typing "y" at the Label disk
35: - Type "Q" and press return to quit disklabel.
36: - At the # prompt, type "fsck -fy /dev/rld0a" and press return.
37: - At the # prompt, type "resize_ffs -y /dev/rld0a" and press return.
38: This may take a few minutes, be patient!
39: - At the # prompt, type "fsck -fy /dev/rld0a" and press return.
40: - At the # prompt, type "mount /dev/ld0e /boot" and press return.
41: - At the # prompt, type "mv /boot/cmdline.txt.orig /boot/cmdline.txt"
42: and press return.
43: - At the # prompt, type "reboot" and press return. When the system
44: comes back up, the root file-system will have been expanded to
45: fill the SD card.
47: # Updating the firmware
48: - [rpi firmware files](https://github.com/raspberrypi/firmware/tree/master/boot)
49: - Copy all files except 'kernel*img' into /boot and reboot
51: # Additional links
52: - [ARM userland utilities](https://github.com/jaredmcneill/userland)
53: - [Additional kernel drivers for VCHIQ](https://github.com/jaredmcneill/vchiq-netbsd)
55: # What works
56: - multi-user boot with root on SD card
57: - serial or graphics console (with EDID query / parsing)
58: - X windows.
59: - USB (host); control, interrupt and bulk transfers. Has some stability issues that are being worked on. man page missing.
60: - USB Ethernet
61: - RNG: works
62: - I²C: works, could use enhancements, man page
63: - SPI: works, could use enhancements, man page
65: # What needs work
66: - VCHIQ; work in progress - will provide audio.
67: - USB (host); isochronous transfers. DMA support.
68: - DMA controller driver / dmover(9) backend
69: - Teach sdhc(4) about dmover; not Raspberry Pi specific
70: - hardfloat; not Raspberry Pi specific
71: - earm ABI; not Raspberry Pi specific
72: - GPIO
