Meta-st-canne2

Meta-st-canne2 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-canne2 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

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

> bitbake rpb-weston-image

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

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
    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/<image>.stimg of=/dev/sdX bs=1M
    where <image>.stimg can be :
        - rpb-weston-image-stih410-b2260.stimg
        - rpb-console-image-stih410-b2260.stimg
    where /dev/sdXX correspond to your usb key storage kernel device entry on your linux PC
    (ex.: /dev/sdc)

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

1. Command 'systemctl Start/Stop Weston' do not work properly, to use instead of:
    kill -9 'Weston process id' => to stop weston
    weston --tty=1 --use-pixman & => to start weston

2. 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'
