Issue:
When flashing an updated model I get the following error:
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x2 addr=0x68 pc=0x10358f924]
I also downloaded the new eim-file to the same directory as the previous one.
Searched everywhere but can not find a solution.
Suggestions are much appreciated.
Hi @GerverA,
I need some more information to be able to assist you:
Hi Shawn,
Project ID: 273272
Arduino Nano
I use a CLI
The original model worked fine. But when I updated the model I got this error
Complete CLI output:

You’re using an untested version of Arduino CLI, this might cause issues (found: 0.34.0, expected: 0.18.x)

Thanks for you help in advance
Also, what do you mean by “updated the model?” How did you go about updating the model?
Hi @shawn_edgeimpulse Shawn,
I use a Rev1.
I first trained a model and flashed it to the board. And it worked fine.
Then I added two features, labeled them, trainde and tested. Went trough all the steps in the studio. Then I build the model in deployment tab.
Can you work with this or do you eed more info?
Hi @GerverA,
Thank you for supplying this information. I can replicate the error on my computer, and it does seem to be a bug. I have filed an issue with our engineering team. In the meantime, could you try deploying as an Arduino library instead of a pre-compiled firmware?
Hi @GerverA,
After chatting with engineering, I learned that this is an arduino-cli issue and not something from Edge Impulse. The error shows up when using arduino-cli v0.34. The workaround is to use arduino-cli v0.33.1. To do that, download arduino-cli v0.33.1 for your system.
From there, copy your 2 .bin files from the deploy ZIP to your arduino-cli folder. So, you should have something like this if you run ls:
shawnhymel@Shawn-Hymel-LQNW70Y61L arduino-cli_0.33.1_macOS_ARM64 % ls
LICENSE.txt
arduino-cli
firmware-arduino-nano-33-ble-sense.ino.bin
firmware-arduino-nano-33-ble-sense.ino.with_bootloader.bin
Connect your Nano 33 BLE to your computer and run the ./arduino-cli board list command to see which port your board is connected to:
shawnhymel@Shawn-Hymel-LQNW70Y61L arduino-cli_0.33.1_macOS_ARM64 % ./arduino-cli board list
Port Protocol Type Board Name FQBN Core
/dev/cu.Bluetooth-Incoming-Port serial Serial Port Unknown
/dev/cu.BoseQC35II serial Serial Port Unknown
/dev/cu.usbmodem1201 serial Serial Port (USB) Arduino Nano 33 BLE arduino:mbed_nano:nano33ble arduino:mbed_nano
Use that port to upload the .bin files to the Arduino with:
./arduino-cli upload -p /dev/cu.usbmodem1201 --fqbn arduino:mbed_nano:nano33ble --input-dir .
This should successfully flash the board. For example, this is what I see:
shawnhymel@Shawn-Hymel-LQNW70Y61L arduino-cli_0.33.1_macOS_ARM64 % ./arduino-cli upload -p /dev/cu.usbmodem1201 --fqbn arduino:mbed_nano:nano33ble --input-dir .

Hi @GerverA,
Could you share with us the Apple hardware you’re using and OS version? This will be helpful for the Arduino to identify / replicate the issue you’re seeing with version 0.34 of the Arduino cli tools.
Thanks,
Arjan
Hi,
Arduino is handling the issue which seems to only occur on MacOS. Here’s the link for tracking: Runtime error using `arduino-cli upload` with version 0.34 · Issue #2304 · arduino/arduino-cli · GitHub
Regards,
Arjan
Thanks @GerverA,
Arduino just released a new version (0.34.2) which should resolve the issue.
