Digi Board
This demo demonstrates the Uniquid Identity and Access Management SDK using the uidcore-c library on ConnectCore 6UL SBC Express Digi board.
Requirements
- Ubuntu 14.04+ with standard development tools
- cmake to compile new firmware
- some software packages from digi.com (next steps)
- libcurl
- libpthread (usually already installed)
You will need two files created when you run the
uniquid deploy aws command. You can choose tu run the below steps in the same environment of the deploy or you will need to copy these two files on your development environment running command:1
scp -i <user-key-pair.pem> [email protected]<ec2-instance-ip-address>:/aws_device_cfg.json .
2
scp -i <user-key-pair.pem> [email protected]<ec2-instance-ip-address>:/caChain-xxxxxxxxxxxxxx.crt .
Copied!
Install Prerequisites
Install these packages on your machine
1
sudo apt install cmake
2

Setup of the board
Setup of Development Environment
- 1.download the toolchain installer from the Digi support page1wget ftp://ftp1.digi.com/support/digiembeddedyocto/2.4/r1/sdk/ccimx6ulstarter/fb/dey-glibc-x86_64-core-image-base-cortexa7hf-neon-toolchain-2.4-r1.shCopied!
- 2.give execution permission to the installer1chmod +x dey-glibc-x86_64-core-image-base-cortexa7hf-neon-toolchain-2.4-r1.shCopied!
- 3.install the toolchain on your host PC1./dey-glibc-x86_64-core-image-base-cortexa7hf-neon-toolchain-2.4-r1.shCopied!
- 4.source the environment setup script, run this command each time you wish to use the SDK in a new shell session1. /opt/dey/2.4-r1/environment-setup-cortexa7hf-neon-dey-linux-gnueabiCopied!
Download and build the demo source code on host PC
- 1.clone the demo repo two options:
- 1.1git clone https://github.com/uniquid/dev-demos.gitCopied!
- 2.1git clone [email protected]:uniquid/dev-demos.gitCopied!
- 2.change directory1cd dev-demos/DIGI-CC-6UL-SBC-ExpressCopied!
- 3.download and patch the dependancy1make clone_repoCopied!
- 4.build the project, the binaries created by this command will be put on the bin directory1makeCopied!
make sure that the environment setup script has been sourced
Transfer the executables on the board
- 1.power on the board using the provided USB cable
- 2.connect to the board using a serial terminal emulator (115200N81) or ssh
- 3.create the demo directory under
/home/root1cd /home/root2mkdir demoCopied! - 4.transfer all the content of the bin directory from the host PC to the
/home/root/demodirectory on the board using scp1cd dev-demos/DIGI-CC-6UL-SBC-Express2scp -r bin/* [email protected]<ipaddress>:~/demoCopied!
Copy certificate and configuration files
Copy in the demo directory the configuration file (aws_device_cfg.json) and the root CA for the mqtt broker (caChain-xxxxxxxxxxxxxx.crt) from your host PC to the board:
1
cd path/of/files
2
scp aws_device_cfg.json [email protected]<ipaddress>:~/demo
3
scp caChain-xxxxxxxxxxxxxx.crt [email protected]<ipaddress>:~/demo/rootCA.crt
Copied!
both these files has been generated by the
uniquid deploy aws command you run some steps ago.Run
- 1.connect to the board over terminal emulator or ssh and go to the
demodirectory1cd /home/root/demoCopied! - 2.run the demo1./S99uniquid-demo startCopied!if you want to run the demo at the board boot copy the above script into the
/etc/rc5.ddirectory1cp /home/root/demo/S99uniquid-demo /etc/rc5.dCopied! - 3.you can check the log running
tailcommand1tail -f /var/log/uniquid-demoCopied! - 4.to allow the board to publish the led status on aws IoT you have to create a contract between the board (user) and the authorizer (provider)
- 5.check here for published messages (please note that the link provided is for the us-east-2 AWS region, you may need to switch to the one you have defined on aws configure)
- 6.you can use the button on the board to switch on/off the led status
