 +**UPDATE 24 Oct 2016**: migrated the system to current upstream U-boot and Linux. Everything seems to be nice and reliable. The limitations section still applies.
 +Some notes on update:
 +  * Needs the latest (from firmware git) ''rt2870.bin'' for stable wifi
 +  * Missing ''nvec_event'' so lid open/close events are not generated
 +  * To be able to use ''synaptics'' X.org driver the ''elantech'' protocol needs to be forced for ''psmouse'' kernel driver
 +  * ''mpv'' works nicely for unaccelerated video playback, including streaming from Youtube and other popular hostings (''ytdl-format=18'' is usually needed)

 I then used my laptop and an SD card, created a single ext2 partition there and unpacked the preinstalled ubuntu rootfs. Copied the ''uImage'' to root and the created modules to ''/lib/modules''. Erased unneeded boot scripts (including ''network-manager'') from ''/etc/init/''. Created there a file to start ''getty'' on ''ttyS0'', 115200 baud. Placed a suitable ''wpa_supplicant.conf'' somewhere on the card. Removed password from ''/etc/shadow'' to give me root login. I then used my laptop and an SD card, created a single ext2 partition there and unpacked the preinstalled ubuntu rootfs.

-===== Tips ===== +And then be sure to read suckless [[tips_and_tricks]].
-  * To manage lid event i'm using https://github.com/gandro/input-event-daemon, it should listen on /dev/input/event4 for LID:0 and LID:1 events. +
-  * I added this to ~/.mplayer/config +
-<code> +
-ao=alsa +
-mixer-channel=Master +
-vo=x11 +
-zoom=1 +
-sws=0 +
-hardframedrop=1 +
-lavdopts=fast=1:skiploopfilter=all +
-</code> +
-  * For watching youtube i use +
-<code> +
-#!/bin/sh +
-cookies_file=`mktemp /tmp/youtube-cookies.XXXXXX` +
-rm $cookies_file +
-url="`youtube-dl --cookies=$cookies_file -g --max-quality 35 $1`" +
-mplayer -cookies -cookies-file $cookies_file -cache 2048 $url +
-rm $cookies_file +
-</code> +
-  * To have automatic software mixing of sound streams copy this to ''/usr/share/alsa/cards/tegra-alc5632.conf'': +
-<code> +
-# default with dmix/dsnoop +
-tegra-alc5632.pcm.default { +
- @args CARD ] +
- @args.CARD { +
- type string +
-+
- type asym +
- playback.pcm { +
- type plug +
- slave.pcm { +
- @func concat +
- strings "dmix:CARD=" $CARD ",RATE=44100" ] +
-+
-+
- capture.pcm { +
- type plug +
- slave.pcm { +
- @func concat +
- strings [ "dsnoop:CARD=" $CARD ",RATE=44100" ] +
-+
-+
-+
- +
-</code> +
-  * To provide additional dedicated sound volume controls without PA add this to ''~/.asoundrc'': +
-<code> +
-pcm.softvol { +
-        @args [ NAME ] +
-        @args.NAME.type string +
-        type softvol +
-        slave.pcm "default" +
-        control.name $NAME +
-+
-</code> +
-And use softvol:<custom name> for the ALSA device, like this: ''aplay -Dsoftvol:"Aplay Dedicated" testmusic.wav'' +
-  * [[http://linuxwireless.org/en/users/Download|compat-wireless]] provides newer wireless drivers that work better but wireless extensions will not be enabled until the kernel is compiled with support for some old pre-mac80211 driver (to select ''CONFIG_WIRELESS_EXT''). +
-  * ''iw dev wlan0 set power_save off'' to improve interactivity when a power-saving compatible AP is used+
