Headless Setup

You can set up your Raspberry Pi without a screen. To do so:

1. Download the Raspberry Pi OS - Bookworm Release

   • Ensure you have the latest Raspberry Pi OS which supports the new Edge Impulse Linux CLI version >= 1.3.0.

You must use 64-bit OS as 32-bit OS is no longer supported Raspberry Pi 5 uses aarch64, which is a 64-bit CPU. If you are installing Raspberry Pi OS for the RPi 5, make sure you use the 64-bit version. Raspberry Pi 5 cannot run armv7 images

1. Flash the Raspberry Pi OS Image

   • Flash the OS image to an SD card using a tool like Balena Etcher.

2. Prepare the SD Card

   • When flashing the OS image, access the advanced options menu in the Raspberry Pi Imager to preconfigure your WiFi and enable SSH.

• Create an empty file called ssh in the boot drive to enable SSH.

1. Boot the Raspberry Pi

   • Insert the SD card into your Raspberry Pi 5 and power it on.

2. Find the IP Address

   • Locate the IP address of your Raspberry Pi using your router's DHCP logs or a network scanning tool. On macOS or Linux, use:

     Copy

     arp -na | grep -i dc:a6:32

     This will display the IP address, e.g., 192.168.1.19.

3. Connect via SSH

   • Open a terminal and connect to the Raspberry Pi:

     Copy

     ssh <username>@192.168.1.19

   • Log in with the default username pi and password raspberry.

With a Screen

If you have a screen and a keyboard/mouse attached to your Raspberry Pi:

1. Flash the Raspberry Pi OS Image

   • Flash the OS image to an SD card as described above.

2. Boot the Raspberry Pi

   • Insert the SD card into your Raspberry Pi 5 and power it on.

3. Connect to WiFi

   • Use the graphical interface to connect to your WiFi network.

4. Open a Terminal

   • Click the 'Terminal' icon in the top bar of the Raspberry Pi desktop.

3. Verifying that your device is connected

That's all! Your machine is now connected to Edge Impulse. To verify this, go to your Edge Impulse project, and click Devices. The device will be listed here.

4. Next steps: building a machine learning model

With everything set up you can now build your first machine learning model with these tutorials:

• Adding sight to your sensors

• Object detection

• Counting objects using FOMO

Looking to connect different sensors? Our Linux SDK lets you easily send data from any sensor and any programming language (with examples in Node.js, Python, Go and C++) into Edge Impulse.

5. Deploying back to device

To run your impulse locally run on your Linux platform:

edge-impulse-linux-runner

This will automatically compile your model with full hardware acceleration, download the model to your local machine, and then start classifying. Our Linux SDK has examples on how to integrate the model with your favourite programming language.

Another option is to download the .eim file directly from Studio, copy it to the device filesystem and run it with the --model-file argument. In this case chmod +x will be required to give the .eim executable permissions.

Enabling and running example-standalone-inferencing-linux

The main route for deploying en Edge Impulse project with SAMA7G54-EK Evaluation Kit is through using .eim. However it is also possible to build example-standalone-inferencing-linux package and run it on the device.

To do that run make menuconfig

Go to Target packages -> Miscellaneous and choose Example Standalone Inferencing Linux package. Paste the project deployment files (edge-impulse-sdk, model-parameters, tflite-model) into buildroot-microchip/buildroot-at91/package/example-standalone-inferencing-linux folder.

Proceed to building the image with make -j $((`nproc` - 1)) You will be able to find custom application file in /home on your target. Run it with ./custom features.txt, where features.txt is a file with raw features.

Note: When using the .eim method it's important to ensure the file has appropriate permissions, so use chmod to set these if needed.

Troubleshooting

Wrong OS bits

If you see the following error when trying to deploy a .eim model to your Raspberry Pi:

Failed to run impulse Error: Unsupported architecture “aarch64”

It likely means you are attempting to deploy a .eim Edge Impulse model file to a 32-bit operating system running on a 64-bit CPU. To check your hardware architecture and OS in Linux, please run the following commands:

uname -m
uname -a
getconf LONG_BIT

If you see something like this:

$ uname -m
aarch64
$ uname -a
Linux raspberrypi 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr  3 17:24:20 BST 2023 aarch64 GNU/Linux
$ getconf LONG_BIT
32

It means that you are running a 32-bit OS on a 64-bit CPU. To run .eim models on aarch64 CPUs, you must use a 64-bit operating system. Please download and install the 64-bit version of Raspberry Pi OS if you see aarch64 when you run uname -m.

The Renesas RZ/G2L is a state-of-the-art general-purpose 64-bit Linux MPU with a dual-core ARM Cortex-A55 processor running at 1.2GHz.

The RZ/G2L EVK consists of a SMARC SOM module and an I/O carrier board that provides a USB serial interface, 2 channel Ethernet interfaces, a camera and an HDMI display interface, in addition to many other interfaces (PMOD, microphone, audio output, etc.). The RZ/G2L EVK can be acquired directly through the Renesas website.

For more technical information about RZ/G2L, please .

Please create an account on Renesas' website to be able to download the packages and files outlined in the subsequent sections.

1. Yocto image preparation/patch/build for G2L

After putting all of these files into a single directory + patch file, you will need to create and patch your G2L yocto build environment as follows (this can be exported into a script that can be run):

You can then invoke your G2L yocto build process via:

Accessing the board using screen

The easiest way is to connect through serial to the RZ/G2L board using the USB mini b port.

1. After connecting the board with a USB-C cable, please power the board with the red power button.

2. Please install screen to the host machine and then execute the following command from Linux to access the board:
3. You will see the boot process, then you will be asked to log in:

   • Log in with username root

   • There is no password

Note that, it should be possible to use an Ethernet cable and log in via SSH if the daemon is installed on the image. However, for simplicity purposes, we do not refer to this one here.

2. Installing Edge Impulse Linux CLI

Once you have logged in to the board, please run the following command to install Edge Impulse Linux CLI

3. Connecting to Edge Impulse

With all software set up, connect your google coral camera to your Renesas board (see 'Next steps' further on this page if you want to connect a different sensor), and run:

This will start a wizard which will ask you to log in and choose an Edge Impulse project. If you want to switch projects run the command with --clean.

4. Verifying that your device is connected

5. Next steps: building a machine learning model

Currently, all Edge Impulse models can run on the RZ/G2L CPU which is a dedicated Cortex A55. In addition, you can bring your own model to Edge Impulse and use it on the device. However, if you would like to benefit from the DRP-AI hardware acceleration support including higher performance and power efficiency, please use one of the following models:

For object detection:

• Yolov5 (v5)

• FOMO (Faster objects More Objects)

For Image classification:

• MobileNet v1, v2

It supports as well models built within the studio using the available layers on the training page.

Note that, on the training page you have to select the target before starting the training in order to tell the studio that you are training the model for the RZ/G2L. This can be done on the top right in the training page.

If you would like to do object detection with Yolov5 (v5) you need to fix the image resolution in the impulse design to 320x320, otherwise, you might risk that the training fails.

With everything set up you can now build your first machine learning model with these tutorials:

6. EON tuner

If you are interested in using the EON tuner in order to improve the accuracy of the model this is possible only for image classification for now. EON tuner supports for object detection is arriving soon.

If you use the EON tuner with image classification, you need to filter the int8 models since they are not supported by the DRP-AI. Also, you need to filter the grayscale models as well. Note that if you leave the EON tuner page, the filter will reset to the default settings, which means you need to re-filter the above models.

7. Deploying back to the device

To run your impulse locally, just connect to your Renesas RZ/G2L and run:

This will automatically compile your model with full hardware acceleration and download the model to your Renesas board, and then start classifying.

Or you can select the RZ/G2L board from the deployment page, this will download an eim model that you can use with the above runner as follows:

Go to the deployment page and select:

Then run the following on the RZ/G2L:

You will see the model inferencing results in the terminal also we stream the results to the local network. This allows you to see the output of the model in real-time in your web browser. Open the URL shown when you start the runner and you will see both the camera feed and the classification results.
