# RAK833 – LoRaGateway – Yocto

## RAK833-LoRaGateway-SolidRun-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](/nxp/imx6/sbc-platform/imx6-software/yocto-for-imx6.md) )

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](https://github.com/RAKWireless/RAK833-LoRaGateway-SolidRun-Yocto.git)

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](https://github.com/RAKWireless/RAK833-LoRaGateway-SolidRun-Yocto.git)

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](https://github.com/RAKWireless/RAK833-LoRaGateway-SolidRun-Yocto.git)

step5 : Building packages

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

step6 : flashing image to SD card([Flashing an SD Card](/other-articles/flashing-an-sd-card.md) ) 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
```
