Deployment: building firmware for Arduino Nano error

Hi there,

I built an image classification model following the Edge Impulse tutorial, but I’m getting an error when I try and build the firmware for deployment to my Arduino Nano 33 BLE. I get the following:

Creating job… OK (ID: 236752)

Any ideas on what the issue might be?

Thanks in advance,

H @Kasim21,

The Arduino Nano 33 BLE doesn’t have a camera sensor which explains why the firmware cannot build (we should prevent building firmware in this situation).
If you wish to use a camera module connected to the Arduino, you can create an Arduino library instead in the Deployment section.

Cheers,
Aurelien

Hi Aurelien,

That makes a lot of sense. Thanks for clarifying.

I’ve also been trying to deploy using the Arduino library. This downloads correctly; however, I then get issues when trying to compile the sketch for deployment to the board (see end of this post for error).

To clarify, I do have an Arducam for connecting to the Arduino. However, for the sketch, I was just copying the raw features from the ‘live classification’ page, and apart from that change, I was just running the sketch as downloaded. I was then later going to build up complexity and connect the Arducam for inputting the raw data.

Can you provide any insights into why the compilation is failing. Is this also to do with the Arduino not having a camera module?

Cheers,

Kas

Error compiling for board Arduino Nano 33 BLE.

This report would have more information with
“Show verbose output during compilation”
option enabled in File -> Preferences.

@Kasim21, FYI the Nano 33 BLE Sense does not have enough RAM or flash to run image classification.

Can you provide any insights into why the compilation is failing. Is this also to do with the Arduino not having a camera module?

No, this seems unrelated. What version of the Arduino core do you have? Under Tools > Board > Boards manager.

Hi @janjongboom ,

Here’s an image of the Arduino core details (I think):

Any ideas?

Also, thanks for clarification re. Nano capabilities. Do you have any alternative newbie development board suggestions. As a background, I’m a wildlife researcher with limited development experience (just in Arduino). Trying to create a hardware prototype (in a three month sprint) to automate wildlife monitoring during safari game drives.

Cheers,

Kas

Hi Kas,

Loos like the latest Arduino core version broke something with our libraries. I will investigate the issue. In the meantime, you can rollback to v1.1.4 to avoid compiling errors.

Regarding easy-to-use dev boards with camera, I would suggest looking at OpenMV Cam H7 Plus: https://docs.edgeimpulse.com/docs/openmv-cam-h7-plus

Aurelien

Filed a bug with the Arduino team here: https://github.com/arduino/ArduinoCore-nRF528x-mbedos/issues/100

But for now reverting back to v1.1.4 indeed solves the issue.

Hi Aurelien, Jan,

Great - thank you for the input and troubleshooting.

Will roll back to 1.1.4 and also will check out the OpenMV Cam H7 Plus.

Cheers,

Kas

We’ve identified a fix with Arduino, going through our testing pipeline now and hopefully live by the end of the day!

Great! Thanks for the rapid turnaround!
