OpenEmbedded / Yocto Project evaluation BSP layer for TQ-Systems ARM SOM

This README file contains information on the content of the meta-dumpling layer.

This layer provides recipes to generate images to help evaluation of TQ-Systems CPU modules and Starterkits. This layer additionally contains optional fixes and extensions for other layers as far as needed / useful for TQ-Systems SOM.

Please see the corresponding sections below for details.

Overview

Dependencies

This layer in the checked out branch depends on:

URI: https://git.yoctoproject.org/poky
branch: zeus
layers: meta

URI: https://github.com/tq-systems/meta-tq.git
branch: zeus
layers: meta-tq

This layer additionally contains optional fixes and extensions for other layers as far as needed for TQ-Systems SOM. Most of these bbappends are implemented under dynamic-layers and are only visible, if the original layer is in your bblayer.conf. For details look for BBFILES_DYNAMIC in Yocto Project documentation.

Patches

Please submit patches against the meta-dumpling layer to the maintainer:

Additionally you can use github's collaboration features.

1. Adding the meta-dumpling layer to your build

Run 'bitbake-layers add-layer /meta-dumpling'

Assuming the tq layer exists in subdir sources at the top-level of your yocto build tree, you can add it to the build system by adding the location of the tq layer to bblayers.conf, along with any other layers needed. e.g.:

BSPDIR := "${@os.path.abspath(os.path.dirname(d.getVar('FILE', True)) + '/../..')}"

  BBLAYERS ?= " \
...
    ${BSPDIR}/sources/meta-tq \
    ${BSPDIR}/sources/poky/meta \
    ...
  "

2. Misc

The meta-dumpling layer defines images recipes for test / evaluation of TQ-Systems SOM:

• tq-image-generic (based on poky core-image-minimal)
• tq-image-qt5 (based on fsl-image-qt5)

Attention: These recipes can be used as a starting point for own customization. Because of the intended usage, a lot for debug and test tools are included. These packages should not go into a production image. Depending on the actual project, security must be taken in account.
