Deployment: building firmware for Arduino Nano error

Kasim21 · August 13, 2020, 9:43pm

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:

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.

Kasim21 · August 15, 2020, 4:52pm

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

janjongboom · August 17, 2020, 9:22am

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.

Kasim21 · August 17, 2020, 12:47pm

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

janjongboom · August 19, 2020, 10:29am

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

Kasim21 · August 19, 2020, 8:18pm

Great! Thanks for the rapid turnaround!

Rocksetta · December 2, 2020, 9:39pm

Does the Nano33Ble really not have enough memory to do any Camera Machine Learning? I have the Nano33BLeSense with ov7670 Cam, the PortentaH7 with the Vision shield but the later only works with micro-python. (It works great by the way.) Do we have any Arduino Camera options? I was hoping the Portenta and Vision cam would come out with Arduino code but that might be a long wait. Any suggestions.

janjongboom · December 3, 2020, 9:16am

@Rocksetta, the Nano 33 BLE Sense can run some models. Think 48x48 input with the smallest transfer learning model, but I still haven’t hooked up any OV7670 cams to it, so not sure how much the frame buffer takes.

For the Portenta: the models work as-is on the board, if you know of any examples to read data from the frame buffer on that target I’ll hook it up as an example - I have the vision shield laying around the office somewhere.
