I am trying to get Node-red working on a Raspberry Pi Zero (it is a Zero W but the wifi chip died)
Should I be able to install NR with the SD card in a modern Pi (Zero 2 W) and it work in a Zero?
I did try this but so far no success.
At the moment I am using a Pi 3a with a wifi dongle but the install repeatedly fails at the same place.
The install log shows

1789 error network This is a problem related to network connectivity.
Since a) it always fails at the same place and b) my ssh connection does not die, I think it must be something other than a network glitch.

### WARNING ###
DO NOT EXPOSE NODE-RED TO THE OPEN INTERNET WITHOUT SECURING IT FIRST
Even if your Node-RED doesn't have anything valuable, (automated) attacks will
happen and could provide a foothold in your local network
Follow the guide at https://nodered.org/docs/user-guide/runtime/securing-node-red
to setup security.
### ADDITIONAL RECOMMENDATIONS ###
- Remove the /etc/sudoers.d/010_pi-nopasswd file to require entering your password
when performing any sudo/root commands:
sudo rm -f /etc/sudoers.d/010_pi-nopasswd
- You can customise the initial settings by running:
node-red admin init
- After running Node-RED for the first time, change the ownership of the settings
file to 'root' to prevent unauthorised changes:
sudo chown root:root ~/.node-red/settings.js
**********************************************************************************
Would you like to customise the settings now (y/N) ?

I'm not clear what you are saying Simon - the OS appears to work on the Zero, and it (RPiOS Legacy) was installed using the imager on my PC.
Of course I can't SSH into it (yet) so can't be certain.
Does the NR installation include any processor specific code which will fail when the SD card is transferred to an older Pi?
Raspbian is not the issue! RPiOS Legacy is for the older CPUs but it will run on a more modern Pi.
Thus I can install the OS, boot it up in a newer Pi and do various stuff like copy over my scripts before moving it to the old Pi. I think
Ethernet over USB gadget mode using a short male - male USB cable to a Pi Zero 2.
I've done this before. The Zero 2 has two IP addresses : wifi 192.168.1.26 and "ethernet" 10.0.0.1. The old Zero has IP 10.0.0.2
It's not exactly practical but I want them to talk to each other to drive contrasting colour LEDs
You need to install the os and nodejs on the zero. The cpu architecture is different ( arm6 vs arm7) and some of the binaries that get installed on a 7 won’t work on a 6. ( other way round is ok)
Thanks Dave. I'm currently redoing it all start to finish on the Pi 3a (which has an older CPU) because the Zero has no network access until it's all up and running. Fingers crossed.
Burned 2021-05-07-raspios-buster-armhf-lite to an SD card, setting up hostname, wifi & ssh in RPi Imager.
Booted the card in a RPi 3a (not 3a+)
Installed Pimoroni Blinkt to permit some LED effects.
Used the standard Node-red install script to install NR and it's prerequisites (node.js v18)
Created a flow to cycle between two Blinkt example scripts.
Shutdown and booted the card in a Pi Zero W (but without working wifi)
The Blinkt examples do cycle between the two patterns demonstrating that RPiOS Buster and Node-red installed on a Pi 3a will run on a Pi Zero W.
I have left out OS updates which would have taken an extra hour or two and maybe broken compatibility. Maybe after the impending gratuitous LED season I'll try updating the OS on a Zero 2 W for speed and see if it still works. Probably not since it will surely replace the kernel.
