RAK833 – LoRaGateway – Yocto


verified on HummingBoard2 rev 1.4 and MicroSOM rev 1.5

Compilation environment requirements

ubuntu16.Other versions of the operating system may have unpredictable errors.

Prepare yocto image

step1 : Download

refer to guide (Yocto for i.MX6 )

First, get Poky:

git clone -b fido git://git.yoctoproject.org/poky.git

Then get the Freescale layers:

cd poky git clone -b fido git://git.yoctoproject.org/meta-fsl-arm git clone -b fido git://github.com/SolidRun/meta-solidrun-arm-imx6.git

Add meta-semtech lora layer

git clone https://github.com/RAKWireless/RAK833-LoRaGateway-SolidRun-Yocto.git

Copy RAK833-LoRaGateway-SolidRun-Yocto/meta-semtech to poky path.

step2 : Copy the file libftdi_1.1.bb to the directory meta/recipes-support/libftdi/ and the directory meta-fsl-arm/openembedded-layer/recipes-support/libftdi/, if the directory libftdi does not exist, create it. refer libftdi_1.1.bb

then run

source oe-init-build-env

step3 : Editing local.conf and bblayers.conf at build/conf

set MACHINE ??= "solidrun-imx6" at local.conf add meta-fsl-arm meta-solidrun-arm-imx6 meta-semtech to bblayers.conf

refer bblayers.conf

step4 : Customizing images for lora image

add IMAGE_INSTALL += "git libftdi libmpsse bash cmake lora-packet-forwarder lora-gateway-dev lora-gateway-staticdev lora-gateway-utils" to core-image-base.bb (../poky/meta/recipes-core/images) ,

refer core-image-base.bb

step5 : Building packages

source oe-init-build-env nice bitbake core-image-base

step6 : flashing image to SD card(Flashing an SD Card ) sudo dd if=core-image-base-solidrun-imx6.sdcard of=/dev/sdb bs=4M conv=fsync

step7 : plug RAK833 module to solidrun HB2 board. make sure the mini-pcie PERST# signal(pin 22) pulled down (default high will cause rak833 function error)

step8 : Start the packet-forwarder application

$ cd /opt/lora-packet-forwarder $ ./lora_pkt_fwd
