Tests

audio in/out

You have to configure inputs and outputs. You can either:

• use alsa ucm profile:
  # zypper ar http://download.opensuse.org/repositories/home:/zombah/openSUSE_Factory_ARM/ openSUSE-home-zombah
  # zypper in paz00-ucm-profiles
  # alsaucm -c PAZ00 reset
• OR configure it manually with alsamixer:

Should be enabled:
DACL2HP Playback Switch
DACR2HP Playback Switch
Int Spk
Speaker Playback Switch (i.e. unmute Speaker)
Should be set:
SpeakerOut Mux to HPOut Mix
SpeakerOut N Mux to RP/+R
Master and speaker playbacks should be unmuted and set to the desired level.

Then you can try to play some files:

$ aplay /usr/share/alsa/sounds/test.wav

And to record some sound:

$ arecord test_input.wav

Configuration

Opentegra

Warning: Opentegra driver not stable yet.

To use opentegra driver you have to:

1. Add devel:Factory:Contrib:Tegra repository:
   # zypper ar http://download.opensuse.org/repositories/devel:/ARM:/Factory:/Contrib:/Tegra/standard/ devel-ARM-Factory-Contrib-Tegra-standard
2. Install opentegra drm and xorg drivers:
   # zypper in xf86-video-opentegra libdrm_tegra0
3. Add XOrg config, to start opentegra driver before fbdev, /etc/X11/xorg.conf.d/00-opentegra.conf with content:

Section "Device"
        Identifier "opentegra"
        Driver "opentegra"
EndSection

Then restart xdm or reboot. Check /var/log/Xorg.0.log log to be sure that driver starts.

Bringup from default rootfs

Download and extract the LimeJeOS rootfs tarball.

Remove the file /etc/sysconfig/network/ifcfg-eth0 since the AC100 does not have an Ethernet interface.

Boot into the system and from USB install a matching kernel package (e.g., worldcitizen's kernel-tegra-ac100), so that you get kernel modules. Reboot.

Download on another machine and install from USB the following packages:

• wireless-tools
• libiw30
• libnl_1-1
• python
• wpa_supplicant
• python-base
• libpython2_7
• libsqlite3
• kernel-firmware

If you then add an appropriate /etc/sysconfig/network/ifcfg-wlan0 config file and restart networking, you should get a working wlan0 interface.

You can now proceed with updating and configuring your system as usual.
