Raspberry Pi Zero 2 W

Help
#1

Can the Raspberry Pi Zero 2 W be used with Edge Impulse? It seems like it should be compatible with the Raspberry Pi Zero 4 other than it will be slower.

Thanks!

Hi @hamslabs,

Haven’t tried it but as it’s the same Cortex A chip as Rasp Pi 3 it should work.

I tried it on Raspberry Pi 3B+ and its working fine, now trying on RPi Zero W but getting error while installing install edge-impulse-linux.
pi@raspberrypi:~ $ npm config set user root && sudo npm install edge-impulse-linux -g --unsafe-perm

sharp: Installation error: Expected Node.js version >=12.13.0 but found 11.15.0
sharp: Please see https://sharp.pixelplumbing.com/install for required dependencies

The error is because node version >12 is required, RPi Zero is armv6, and NodeJS do not have it for armv6. version below 12 are available for armv6.

I was able to install it on my pi zero 2 W running 64bit raspberry pi OS bookworm by adding allocated swap memory:

sudo apt update
sudo apt upgrade


#increase swap file memory
free -h
sudo fallocate -l 1G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
free -h
