I. Building the meta-fri2 BSP layer
===================================

In order to build an image with BSP support for a given release, you
need to download the corresponding BSP tarball from the 'Board Support
Package (BSP) Downloads' page of the Yocto Project website.

Having done that, and assuming you extracted the BSP tarball contents
at the top-level of your yocto build tree, you can build an fri2 image
by adding the location of the meta-intel and meta-fri2 layers to
bblayers.conf, e.g.:

  yocto/meta-intel \
  yocto/meta-intel/meta-fri2 \

The meta-fri2 layer contains support for fri2-noemgd machine configuration.
The previously supported fri2 machine with the proprietary EMGD graphics
driver has been retired. The 'fri2-noemgd' machine configuration uses
the open source 'vesa' kernel driver.

To enable the layer add the following to the local.conf file:

  MACHINE ?= "fri2-noemgd"

You should then be able to build an fri2 image as such:

  $ source oe-init-build-env
  $ bitbake core-image-sato

At the end of a successful build, you should have a live image that
you can boot from a USB flash drive (see instructions on how to do
that below, in the section 'Booting the images from /binary').

As an alternative to downloading the BSP tarball, you can also work
directly from the meta-intel git repository.  For each BSP in the
'meta-intel' repository, there are multiple branches, one
corresponding to each major release starting with 'laverne' (0.90), in
addition to the latest code which tracks the current master (note that
not all BSPs are present in every release).  Instead of extracting a
BSP tarball at the top level of your yocto build tree, you can
equivalently check out the appropriate branch from the meta-intel
repository at the same location.


II. Booting the images in /binary
=================================

This BSP contains bootable live images, which can be used to directly
boot Yocto off of a USB flash drive.

Under Linux, insert a USB flash drive.  Assuming the USB flash drive
takes device /dev/sdf, use dd to copy the live image to it.  For
example:

# dd if=core-image-sato-fri2-noemgd.hddimg of=/dev/sdf
# sync
# eject /dev/sdf

This should give you a bootable USB flash device.  Insert the device
into one of the USB host ports on the target, and power on.  This
should result in a system booted to the Sato graphical desktop.

If you want a terminal, use the arrows at the top of the UI to move to
different pages of available applications, one of which is named
'Terminal'.  Clicking that should give you a root terminal.

If you want to ssh into the system, you can use the root terminal to
ifconfig the IP address and use that to ssh in.  The root password is
empty, so to log in type 'root' for the user name and hit 'Enter' at
the Password prompt: and you should be in.

If instead of a live image, you would like to prepare an EFI bootable
partitioned image, use the mkefidisk.sh script provided in the scripts
directory of this BSP. Future versions of the images have an EFI
installer integrated into the live image.

----

If you find you're getting corrupt images on the USB (it doesn't show
the syslinux boot: prompt, or the boot: prompt contains strange
characters), try doing this first:

# dd if=/dev/zero of=/dev/sdf bs=1M count=512


III. Device Notes
================================
a. BIOS and Firmware

Units provided from the Yocto Project Fish River Island 2 Giveaway
Program are preconfigured with the Intel provided Fast Boot EFI
firmware. This firmware will search the available devices (USB, SD,
and mSATA) for a valid EFI payload at "EFI\BOOT\BOOTIA32.EFI". If it
fails to find one, it will launch the EFI shell and optionally execute
a "startup.nsh" script if it finds the script on the available storage
devices. It searches the devices in the following order: USB, SD,
mSATA.

Units acquired via other channels may have the Kontron supplied APTIO
(AMI) BIOS. This is a PCBIOS and EFI firmware with a traditional BIOS
configuration menu which can be used to define a variety of boot
configurations.

b. Serial Port
--------------
The FRI2 has an optional serial daughter card providing a serial
console via the micro-USB port on the top of the device adjacent the
SIM card slot.

The UART from the EG20T is connected to a TI UART-to-USB device
(TUSB3410) which appears as a serial port on the host computer. From a
Linux host, load the driver with the following options:

# modprobe ti_usb_3410_5052 vendor_3410=0x0451 product_3410=0x5053

In future versions of the Linux kernel (3.4 and later), the
vendor and product codes are detected automatically.

When you power on your FRI2, your host will discover a serial device
and name it /dev/ttyUSB0 (or similar). You can communicate with this
device at 115200 8N1 using your preferred terminal emulator.

If using the Intel provided Fast Boot EFI firmware, no additional
configuration is required. If using the APTIO (AMI) BIOS, use the
following settings to configure console redirection in the BIOS menu:

  Advanced
    Serial Port Console Redirection
      COM2
      Console Redirection [Enabled]
      Console Redirection Settings
        Terminal Type         [ANSI]
        Bits per second       [115200]
        Data Bits             [8]
        Parity                [None]
        Stop Bits             [1]
        Flow Control          [None]
        Recorder Mode         [Disabled]
        Resolution 100x31     [Disabled]
        Legacy OS Redirection [80x24]

c. HDMI
-------
The FRI2 has two micro HDMI ports. For the Intel provided Fast Boot
EFI firmware, the one closest to the bottom of the device is the
primary display. For the APTIO (AMI) BIOS, the jack nearest the 1/8"
audio jacks is the primary display.

d. Power Reset
--------------
The recessed button adjacent the LEDs on the top of the device is a
power reset button.

e. Accelerometer
----------------
The LIS331DLH accelerometer is connected to the I2C bus on the CPLD on
the compute module. The driver for this chip is under active
development and will be included in the BSP once completed.

f. GPIO
-------
The FRI2 has two I2C PCA555x GPIO devices used for internal control
signals. These have not been exposed in the current release of the
BSP, but may be in the future. Regardless, these would not provide
general purpose IO with which to read or drive additional signals.

g. MMC
------
The FRI2 provides two microSD card MMC devices. One is located
adjacent the 1/8" audio jacks, another is located on the board inside
the chassis. These devices can be used to boot the device, or as
secondary storage.

h. 802.11
---------
The Intel Corporation Centrino Advanced-N 6205 that ships with the
FRI2 is supported. You can use connman-gnome to configures the
interface.

i. 802.15.4
-----------
The TI CC2531 802.15.4 radio is a USB ACM modem. The MAC is enabled by
issuing the following command:

# echo J > /dev/ttyACM0

The bank of 3 LEDs nearest the power reset button will change if this
command is executed successfully. If you have a 3G modem installed,
the 802.15.4 device may appear as /dev/ttyACM3 instead.

No further testing or integration has been done.

j. Audio
--------------------
The FRI2 has an 1/8" analog output (nearest the antennae), a line-in
input below that, as well as SPDIF over HDMI. These can be tested
using the alsa-utils package. The aplay -l command will list both
playback devices:

# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: MID [HDA Intel MID], device 0: ALC262 Analog [ALC262 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: MID [HDA Intel MID], device 3: ALC262 Digital [ALC262 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Using a sample WAV file, you can use aplay to play to either device:

Over analog:
# aplay -D plughw:0,0 sample.wav

Over HDMI:
# aplay -D plughw:0,3 sample.wav


k. Optional Devices
-------------------
The FRI2 has two mini-PCIe slots internally. The device ships with a
half-length wireless card installed. This can be replaced with a
wireless + bluetooth card. The other slot is available for use with
cellular cards or mSATA SSDs.

The Ericsson F5521gw 3G modem has been verifed with the FRI2 images.
Note that the connman-gnome UI does not allow for configuring the
cellular interface. The ofono-tests package can be used to configure
the modem and bring up an interface.


IV. Known Issues
----------------
a. EFI
------
The APTIO (AMI) BIOS does not yet boot the EFI payload provided on the
FRI2 live image. This is a known issue under investigation. If using
this firmware, boot using PCBIOS mode, rather than EFI.  The Intel
provided Fast Boot EFI firmware will boot the EFI payload.

b. Client USB is disabled
-------------------------
The micro-USB port adjacent the primary HDMI port is intended for Client
USB functionality, but is not supported on current revisions of the
device.

c. Audio over secondary HDMI port only
--------------------------------------
While audio over HDMI has been shown to work, it seems to only work over
the secondary (bottom-most) HDMI port. There does not appear to be a
deterministic way of getting the device to output the signal (video and
audio) over the secondary port.
