meta-pubnub

This repository provides PubNub Example for SAMA5D3 Xplained on Poky.

This client example is a fairly trivial C PubNub app that connects your board to the world via a PubNub channel.

• Messages are sent to PubNub dev console in cloud whenever the PB_USER button is pressed.
• According to received messages by SAMA5D3 Xplained, the blue and red LEDs can be switched.

##Build procedure #####1. Clone yocto/poky git repository

git clone git://git.yoctoproject.org/poky

#####2. Checkout dizzy branch

cd poky
git checkout origin/dizzy -b my_branch

#####3. Clone meta-openembedded git repository

git clone git://git.openembedded.org/meta-openembedded

#####4. Checkout proper meta-openembedded branch

cd meta-openembedded
git checkout origin/dizzy -b my_branch
# come back to the "poky" directory for next steps
cd ..

#####5. Clone meta-qt5 git repository

git clone git://github.com/meta-qt5/meta-qt5.git

#####6. Checkout proper meta-qt5 branch

cd meta-qt5
git checkout origin/master -b my_branch
# come back to the "poky" directory for next steps
cd ..

#####7. Clone meta-atmel layer

git clone git://github.com/linux4sam/meta-atmel.git meta-atmel

#####8. Checkout proper meta-atmel branch

cd meta-atmel
git checkout origin/dizzy -b my_branch
# come back to the "poky" directory for next steps
cd ..

#####9. Clone meta-wilc layer

git clone https://github.com/atwilc3000/meta-wilc.git
# come back to the "poky" directory for next steps
cd ..

#####10. Clone meta-pubnub layer

git clone https://github.com/atwilc3000/meta-pubnub.git
# come back to the "poky" directory for next steps
cd ..

#####11. Initialize build directory

source oe-init-build-env build-atmel

#####12. Add meta-wilc layer patch to bblayer configuration file

vim conf/bblayers.conf

# LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
LCONF_VERSION = "6"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

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

BBLAYERS ?= " \
  ${BSPDIR}/meta-atmel \
  ${BSPDIR}/meta-qt5 \
  ${BSPDIR}/meta \
  ${BSPDIR}/meta-yocto \
  ${BSPDIR}/meta-yocto-bsp \
  ${BSPDIR}/meta-openembedded/meta-oe \
  ${BSPDIR}/meta-openembedded/meta-networking \
  ${BSPDIR}/meta-openembedded/meta-python \
  ${BSPDIR}/meta-openembedded/meta-ruby \
  ${BSPDIR}/meta-wilc \
  ${BSPDIR}/meta-pubnub \
  "

#####13. Edit local.conf to specify the machine, location of source archived, package type (rpm, deb or ipk)

vim conf/local.conf

[...]
MACHINE ??= "sama5d3-xplained"
[...]
DL_DIR ?= "your_download_directory_path"
[...]
PACKAGE_CLASSES ?= "package_ipk"

Here are the machines that are supported:

• MACHINE ??= "at91sam9rlek"
• MACHINE ??= "at91sam9m10g45ek"
• MACHINE ??= "at91sam9x5ek"
• MACHINE ??= "sama5d3xek"
• MACHINE ??= "sama5d3-xplained"
• MACHINE ??= "sama5d4ek"
• MACHINE ??= "sama5d4-xplained"

To get better performance, use the poky-atmel distribution by also adding that line:

DISTRO = "poky-atmel"

Input correct package name

#Atmel
IMAGE_INSTALL_append += " \
  linux-firmware-atmel-wilc3000 \
  wilc3000 
  libpubnub
  pubnub

#####14. We found that additional local.conf changes are needed for our QT demo image. You can add these two lines at the end of the file:

vim conf/local.conf

[...]
LICENSE_FLAGS_WHITELIST += "commercial"
SYSVINIT_ENABLED_GETTYS = ""

#####15. Build Json-c

bitbake json-c

#####16. Build Atmel demo images

bitbake atmel-qt5-demo-image
