Pi Zero W - emonSD-10Nov22 - Nothing on boot

[ecylcje (Chris Eagles)]

Hello,

I’m sure this must have been covered elsewhere, but I’ve searched and found nothing.

I’ve got a headless Pi Zero W and no matter how I flash the emonSD - 10Nov22 I just cannot get it to boot and connect to my network via WiFi (or via a USB Network dongle).

I’ve used RP Imager and BalenaEtcher and followed all the steps with / without network. It doesn’t connect to my network or create an AP when no network configured. I thought it might be the SD card but I’ve flashed an OOB PI image on it and it connects instantly. The Pi Zero W and SD card is definitely working.

Have I done something really stupid and the Pi Zero W isn’t supported?

Thanks in advance,

Chris

There have been issues with the PiZero because of the architecture.

I’m pretty sure we found you needed to build emoncms from the scripts rather than the pre-built image. I thought something had been added to the docs to this effect, but cannot find it. @TrystanLea - I thought we had added a list of compatible Pis, but cannot see it so if it is there, it isn’t prominent enough

I was also sure that I had done a build guide for the Pi Zero, but cannot find it. Best I can find is this thread from Feb.

However, RaspberryOS has changed since then so it might no longer work

Follow this instruction to install base OS. EmonScripts: SD Card Preparation for RaspberryPi — OpenEnergyMonitor 0.0.1 documentation

Don’t include the WiFi module in the emonscript config.

@Bramco I’ll not get to test it until next week. Assuming you are content to get the partitions setup, then Download the script but use the master branch not the stable branch (edit the curl command). Edit init.sh to master branch. Run init script. It does an OS upgrade. Hook the Pi up to a monitor so you can see what is happening (if it goes pear shaped). Stop the install script y, Edit the config file and replace all instances of stable with master for the git repos. Set in…

I have edited the process above 10 Feb 16:00 I won’t change it on git for now, ideally we will look and see if it ARMv6 or v7 so automate it. Just comment out these lines I’m just about to rerun myself.

Just ran the stable install, and it installs fine on an ARMv6 platform. Not tested it on an ARMv7, but hopefully that will be fine. [edit] Don’t install the Wi-Fi module - configure Wi-Fi when flashing image. Do reboot at the end.
