Raspberry Pi Zero W for Magic Mirror

Jakobud

I recently got a RPi Zero 2W and installed Raspberry Pi OS (latest legacy version from the RPi Imager) and then installed MM2 using the script (which worked really well). But Chromium will not run for me. Everything I read says that Chromium will not work on the RPi Zero 2 because it’s not fast enough or doesn’t have enough memory. Chromium absolutely will not start on mine. What am I missing here?

@Jakobud hm… try the not legacy image, runs great on my pi02w

legacy really for armv6l

are you using the full image?

Jakobud

After choosing RPi Zero 2 W it recommends this one to me, which is what I used. What version should I be using instead exactly?

sdetweil

@Jakobud I don’t use the raspberry imager cause of problems and this filtering

I use the list and then image myself

Jakobud

@sdetweil Okay which one do you use specifically?

sdetweil

@Jakobud the top one on that page

@sdetweil I am ripping my hair out trying to get MM running on a Pi Zero W. I’ve followed all of your (super helpful) suggestions across multiple posts, but no matter what I do, I keep getting:

[PM2][ERROR] File ecosystem.config.js not found

any time I try to execute pm2 start.

I’ve run your upgrade / update scripts from github, I’ve removed Chromium and replaced it with Firefox, I’ve uninstalled and reinstalled ten different flavors of the PiOS, I’ve tried the MagicMirrorOS that someone else posted, etc. All with no luck.

Do you have any ideas what could be the problem here?

Thanks in advance,
dvg

File ecosystem.config.js no found

well, I haven’t seen that…, BUT it sounds like from a google search thgat you have the wrong node js version installed…

but

flash the sd card… its a pi02W, a 3 in pi0 form factor

then run my install script. don’t dop anything else first

you can try to see if you can fixup pm2 first…

pm2 stop all
pm2 status
this will display a line

pi@raspberrypi42:~ $ pm2 status
┌────┬────────────────────┬──────────┬──────┬───────────┬──────────┬──────────┐
│ id │ name               │ mode     │ ↺    │ status    │ cpu      │ memory   │
├────┼────────────────────┼──────────┼──────┼───────────┼──────────┼──────────┤
│ 0  │ MagicMirror        │ fork     │ 0    │ online    │ 0%       │ 2.7mb    │
└────┴────────────────────┴──────────┴──────┴───────────┴──────────┴──────────┘

you can use the name or number on any line

pm2 delete 0
pm2 save -f
then run
bash -c “$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/fixuppm2.sh)”

to recreate the app in pm2.

lets see…

else redo the install as above

I’m sorry but I don’t understand what this means. Which PiOS should I flash? I have been trying with the Legacy, 32-bit.

(If it makes a difference, I actually have a Raspberry Pi Zero W Rev 1.1. I don’t think it’s a 2.)

Thank you!

sdetweil

@davidgagne ok, if it IS a pi0W, then 32 bit legacy image

flash sd card, boot to the desktop, use terminal window or ssh

then my install script.

they have removed the chromium browser, for armv6l, so you will have to use firefox or one of the others… midori or surf

so YOU MUST use the environment variable in
~/MagicMirror/installers/mm.sh to set the browser to use ( all have to be installed manually)
