Meta-st-cannes2

Meta-st-cannes2 is a layer containing the ST bsp metadata.

This layer relies on OpenEmbedded build system that is provided through Bitbake and OpenEmbedded-Core layers or Poky layer; all part of the Yocto Project.

The Yocto Project has extensive documentation about OE including a reference manual which can be found at: http://yoctoproject.org/documentation

For information about OpenEmbedded, see the OpenEmbedded website: http://www.openembedded.org/

Configuration via Openembedded

Layer depends:

URI: git://git.openembedded.org/openembedded-core
layers: meta
branch: krogoth

URI: git://git.openembedded.org/meta-openembedded
layers: meta-oe
branch: krogoth

URI: git://git.openembedded.org/bitbake
branch: 1.30

Machine to be used with Meta-st-cannes2 layer: stih410-b2260

---

Configuration via Linaro

To download the software:

mkdir stih410-b2260

cd stih410-b2260

repo init -u https://github.com/96boards/oe-rpb-manifest.git -b krogoth

repo sync

To compile the software:

cd stih410-b2260

source ./setup-environment

-> for Machine choose: stih410-b2260

-> for Distributions choose: rpb-wayland

bitbake rpb-weston-image

Generated tar.gz is stored in stih410-b2260/build-rpb-wayland/tmp-rpb_wayland-glibc/deploy/images/stih410-b2260/

Warning: if you run the environment set for the second time and you want to force the Machine and Distro selection, clean up your environment by following commands :

unset MACHINE

unset DISTRO

unset DISTROLAYERS

To Populate SDCard or Usb Key

The RPB build for stih410-b2260 machine generate a raw image which contains an image ready to flash on sdcard or USB key for b2260.

The image generated have the extension stimg and contains two partitions:

• BOOT: fat32 parition which contains kernel, devicetree and boot script
• rootfs: ext4 partition which contains rootfs

To flash a SDCard:

dd if=stih410-b2260/build-rpb-wayland/tmp-rpb_wayland-glibc/deploy/images/stih410-b2260/image.stimg of=/dev/mmcblkX bs=1M conv=fdatasync

where "image.stimg" can be :

• rpb-weston-image-stih410-b2260.stimg
• rpb-console-image-stih410-b2260.stimg

where ""/dev/mmcblkX" correspond to your sdcard kernel device entry on your linux PC (ex.: /dev/mmcblk0)

To flash a Usb Key:

dd if=stih410-b2260/build-rpb-wayland/tmp-rpb_wayland-glibc/deploy/images/stih410-b2260/.stimg of=/dev/sdX bs=1M conv=fdatasync

where "image.stimg" can be :

• rpb-weston-image-stih410-b2260.stimg
• rpb-console-image-stih410-b2260.stimg

where ""/dev/mmcblkX" correspond to your sdcard kernel device entry on your linux PC (ex.: /dev/mmcblk0)

To boot from SDCard

1-Insert SDCard in your board.

2-Connect your board to Linux PC via the serial cable.

3- Supply your board

4- Launch minicom on serial port connected to the board from the Linux PC

minicom -D /dev/ttyUSB0

5- wait the end of boot login is requested : type root

To boot from Usb Key

1- Insert Usb Key in your board (without SDCard plugged).

2- Connect your board to Linux PC via the serial cable.

3- Supply your board

4- Launch minicom on serial port connected to the board from the Linux PC

minicom -D /dev/ttyUSB0

5- wait the end of boot login is requested : type root

Known limitations

Command 'systemctl Start/Stop Weston' do not work properly:

One should use:

kill -9 'Weston process id' => to stop weston

weston --tty=1 --use-pixman & => to start weston

Keyboard connected to 96Board is configured in QWERTY by default:

to have the AZERTY configuration: './etc/xdg/weston/weston.ini' file must be modified by uncommenting 2 lines below line '# for azerty keyboard'
