This README file contains information on building the meta-valleyisland
|
||||
BSP layer, and booting the images contained in the /binary directory.
|
||||
Please see the corresponding sections below for details.
|
||||
|
||||
The Valley Island BSP consists of two versions:
|
||||
1. 32-bit Valley Island
|
||||
2. 64-bit Valley Island
|
||||
|
||||
The BSP is made specifically for Intel Atom E38XX Processor E38XX
|
||||
Development Kit (formerly known as Valley Island). This BSP integrates
|
||||
Intel Graphics for Linux driver as the integrated graphics.
|
||||
|
||||
Valley Island BSP is meant to support Valley Island Development
|
||||
Kit, "Bayley Bay" CRB and "Bakersport" CRB.
|
||||
|
||||

I. Building the meta-valleyisland 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 that done, and assuming you have extracted the BSP tarball contents
|
||||
at the top-level of your Yocto build tree, you can build a valleyisland
|
||||
image by adding the location of the meta-valleyisland layer to
|
||||
bblayers.conf, along with the meta-intel layer itself (to access
|
||||
common metadata shared between BSPs) e.g.:
|
||||
|
||||
yocto/meta-intel \
|
||||
yocto/meta-intel/meta-isg/meta-valleyisland \
|
||||
|
||||
To enable the 32-bit Valley Island layer, add the valleyisland-32 MACHINE to local.conf:
|
||||
|
||||
MACHINE ?= "valleyisland-32"
|
||||
|
||||
To enable the 64-bit Valley Island layer, add the valleyisland-64 MACHINE to local.conf:
|
||||
|
||||
MACHINE ?= "valleyisland-64"
|
||||
|
||||
The meta-valleyisland contains support for Intel HD Audio. However, HD Audio
|
||||
driver is dependent on gstreamer plugins and ffmpeg plugins to work properly.
|
||||
These gstreamer plugins require license flags in order to be included in the build.
|
||||
|
||||
Add "commercial" in the LICENSE_FLAGS_WHITELIST in local.conf. For example:
|
||||
|
||||
LICENSE_FLAGS_WHITELIST = "commercial"
|
||||
|
||||
You should then be able to build a valleyisland 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 (or builds) live images which must be converted to a
|
||||
partitioned image format in order to boot them on the Valley Island
|
||||
Development Kit, Bayley Bay CRB and Bakersport CRB.
|
||||
|
||||
You can deploy the hddimg image to a USB or SATA device. You will
|
||||
need to know the device name on your host as well as the device name on
|
||||
the target. Be careful with this step as using the wrong host device can
|
||||
result in overwriting data on your host machine.
|
||||
|
||||
Under Linux, USB and SATA devices typically appears as /dev/sdb,
|
||||
/dev/sdc, etc. Watching your system messages as you connect the device
|
||||
will tell you exactly which device name is assigned to the device.
|
||||
On the Valley Island platform, assuming only one storage device is
|
||||
attached at boot, a USB or SATA device will be /dev/sda.
|
||||
|
||||
After inserting the boot media into your host machine and determining
|
||||
your host and target device, create the image using the mkefidisk.sh
|
||||
script, provided by poky under scripts/contrib/. Note that root
|
||||
privileges are required. For example, using an USB device which appears
|
||||
as /dev/sdc on the host:
|
||||
|
||||
$ sudo ./mkefidisk.sh /dev/sdc core-image-sato-valleyisland-32.hddimg /dev/sda
|
||||
|
||||
Follow the prompts on the screen to confirm the action.
|
||||
|
||||
Insert the device into the Valley Island platform and power on. This
|
||||
should result in a system booted to the Sato graphical desktop.
|
||||
|
||||
The root password is empty on the Poky reference distribution images.
|
||||
|
||||

||||
III. Device Notes
|
||||
=================
|
||||
a. Boot Loader
|
||||
--------------
|
||||
BIOS : Bayley Bay 072_011
|
||||
EC : KSC v3.10 for Bayley Bay/Bakersport CRB Fab3
|
||||
|
||||
Required settings in BIOS
|
||||
|
||||
Turn off Secure-boot:
|
||||
Device Manager -> System Setup -> Boot -> Security Boot -> Disable
|
||||
|
||||
Turn off LPE Audio Support:
|
||||
Device Manager -> System Setup -> South Cluster Configuration ->
|
||||
Audio Configuration -> LPE Audio Support -> Disable
|
||||
|
||||
Please use EFI mode for all boot medium types, i.e. USB disk and Hard Disk.
|
||||
Setting in BIOS:
|
||||
|
||||
Choose boot medium:
|
||||
Boot Manager -> EFI (Hard Drive/USB Device)
|
||||
|
||||
Save settings:
|
||||
Boot Maintenance Manager -> Boot Options -> Change Boot Order ->
|
||||
Change the order -> Commmit Changes and Exit
|
||||
|
||||
|
||||
b. I/O drivers
|
||||
--------------
|
||||
The I2C controller driver supports fast mode by default.
|
||||
To enable standard mode, appends the arguments to kernel command line.
|
||||
|
||||
"i2c-designware-pci.force_std_mode=1" (PCI mode)
|
||||
"i2c-designware-platform.force_std_mode=1" (ACPI mode)
|
||||
|
||||
|
||||
c. LPIO ACPI enumeration support
|
||||
--------------------------------
|
||||
Required settings in BIOS
|
||||
|
||||
Turn on ACPI mode
|
||||
Device Manager -> System Setup -> South Cluster Configuration ->
|
||||
LPSS & SCC Configuration -> LPSS & SCC Device Mode -> ACPI mode
|
||||
|
||||
Some LPSS devices are hidden in ACPI mode to support Windows. To enable
|
||||
these devices, toggle the following in the BIOS Menu.
|
||||
|
||||
Device Manager -> System Setup -> South Cluster Configuration -> Miscellaneous
|
||||
Configuration -> Unsupported LPSS Device and select "Unhide"
|
||||
|
||||
|
||||
IV. Known Limitations
|
||||
=====================
|
||||
a. I/O drivers
|
||||
--------------
|
||||
HSUART:
|
||||
|
||||
When runninig PCI mode HSUART at baud rate 2M and above, you may observe
|
||||
kernel message "serial8250: too much work for irq...". Most of the time it
|
||||
won't disrupt the transfer and able to complete without data corruption.
|
||||
However, occasionally your transfer may halt when that kernel message appear.
|
||||
In this case, you would need to re-open the HSUART port.
