Yocto BSP Layer - For STLinux sh4 based Set-Top-Boxes
This is the general hardware specific BSP overlay for STLinux based devices. It should be used with openembedded-core (not old-style org.openembedded.dev).
This layer in its entirety depends on:
URI: http://git.yoctoproject.org/git/poky
branch: krogoth
revision: HEAD
How to use it with yocto
Clone poky
git clone http://git.yoctoproject.org/git/poky poky
Switch to dizzy branch
cd poky
git checkout -b krogoth origin/krogoth
Independent Steps from poky/oe-core
Clone meta-stlinux
git clone https://github.com/seife/meta-stlinux.git meta-stlinux
Initialize the oe-core build environment
# Initialize the oe-core build environment and edit configuration files
#
# This following command line line will create your build directory, setup your build environment,
# automatically place the current work directory inside the build dir and
# print out some useful information on how to bitbake packages.
# You can rerun this command every time you want to re-setup your build environment!
source oe-init-build-env spark-build
Add meta-stlinux in bblayers.conf
vim conf/bblayers.conf
...
BBLAYERS ?= " \
/home/user/poky/meta \
/home/user/poky/meta-yocto \
/home/user/poky/meta-yocto-bsp \
/home/user/poky/meta-stlinux \
"
...
Set MACHINE to spark and package type to ipk in local.conf
vim conf/local.conf
...
# Currently only spark hardware is supported
MACHINE ??= "spark"
...
PACKAGE_CLASSES ?= "package_ipk"
...
Run bitbake:
bitbake core-image-minimal
Prerequisite
For the coprocessor firmware loading you have to provide the coprocessor firmware. Put the files either in the folder /data/stslave_fw/${MACHINE} or overwrite the variable "BINARY_STSLAVE_FW_PATH" in your conf/local.conf file. These files are audio.elf and video.elf. For spark this looks like this:
- /data/stslave_fw/spark/video.elf
- /data/stslave_fw/spark/audio.elf
These files can be extracted from a alternative image and are not part of this repository.
Caution!
Currently the only supported boot mechanism is booting a USB Stick. Fore more information have a look at this wiki page: Boot-from-USB-Stick
