1. Article purpose[edit source]
The purpose of this article is to explain how to integrate the LoRa Concentrator Module with STM32MP157F-DK2, managed by Linux on Cortex®-A7. This will help to configure STM32MP1 discovery kit either as a loragateway or running the ChiprStack open source component for LoRaWAN networks.
2. Prerequisites[edit source]
2.1. Hardware prerequisites[edit source]
- STM32MP157F-DK2

2.2. Software prerequisites[edit source]
3. Hardware setup[edit source]
The lora concentrator module should be connected to 40 pin connector
3.1. ST hardware[edit source]
3.2. Additional hardware[edit source]
4. Software setup[edit source]
5. Building the distribution package[edit source]
Step 1. Download and compile the STM32MP1 Distribution Package
Step 2. Follow the default Example_of_directory_structure_for_Packages suggested by ST wiki page to follow this document synchronously.
Step 3. Download and clone the layer "meta-st-loragateway" to "meta-st" layer.
cd $HOME/STM32MPU_workspace/STM32MP15-Ecosystemv3.1.0/Distribution-Package/openstlinux-5.10-dunfell-mp1-21-11-17/layers/meta-st
git clone https://github.com/amitemrkumar/meta-st-loragateway
Step 4. Set up the build configuration.
DISTRO=openstlinux-weston MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.sh
Step 5. Add the meta-st-loragateway layer to build configuration.
bitbake-layers add-layer ../layers/meta-st/meta-st-loragateway/
Step 7. Build your layer separately and then build the complete Distribution Layer.
bitbake st-image-weston
Note: Building the Distribution Package for the first time may take several hours. However, it takes only few minutes to build meta-nfc6 layer and install the executables in the final images. Once the build is complete, the images are present in the following directory: build-<distro>-<machine>/tmp-glibc/deploy/images/stm32mp1.
Step 8. Follow instructions on ST wiki page:Flashing the built image to program the new built images onto the Discovery kit
6. How to run the LoRaWAN gateway application on STM32MP157F-DK2[edit source]
Step 1. Read the ipaddress of the STM32MP157 discovery kit.
