Trouble updating Magic Mirror on Raspberry Pi Zero 2W

[sdetweil]

@wyovino what os is it?

do
lsb_release -a

latest MagicMirror doesn’t run on buster

[sdetweil]

@wyovino pi02w is a pi3+ in a pi0 form factor
so it runs all the 32 and 64 bit os. but should stay 32 bit due to the small memory space

[wyovino]

@sdetweil It’s Buster. I guess I’ll have to build it from scratch again. I remember having a hard time getting the PIR Sensor module to work, not sure if works under bookworm.

@wyovino use my backup/restore scripts to copy to new system

@sdetweil I’ve been struggling with this for a week. Nothing new seems to play well with Pi Zero 2. I built the OS and MM from scratch on a USB drive and after many tries finally got it working. When I moved the USB drive to the Pi Zero 2 that’s mounted in my mirror it didn’t work. I tried it in the Zero 2 that I used to build the software and it didn’t work there either. However when I plug it into a Pi 4 it works fine. It seems that the changes they made in Bookworm ignored the needs of the Pi Zero 2.

I also built it from scratch on a 32gb microSD card and that worked. I tried using PiShrink to reduce the image size so it would fit on my 16gb USB drive. It appeared to work, but the Zero 2 wouldn’t boot from it. The way my mirror is set up, I can’t access the SD slot.

@wyovino ok, I’ll try to find some time tomorrow or Wednesday to look at my pi02w and see what I can get done.

I would start w the legacy 32 bit bullseye image myself

[wyovino]

@sdetweil I did try Bullseye and that failed to install MM. I guess I could try again. This is so frustrating. I can can it working on one Pi Zero 2, but not another one. I’m done with this for now. My older version is working fine.

@wyovino I use my script all the time.
I’ve spent too many hours working out the kinks to do it manually.

[sdetweil]

@wyovino So, I flashed a 32gb sd card… age unknown. with the 32bit legacy OS + Desktop ( not with recommended software, cause its office, … I don’t need that on a mirror)

booted, did setup, changed hostname, enabled ssh,
reboot

ssh’d in and checked swap space , 99 meg, none used,
I then ran my install script…

it increased swap space to 871

               total        used        free      shared  buff/cache   available
Mem:             426         152          88           0         185         221
Swap:            871          48         823

I then watched install run thru without problems, updated node/npm
installed pm2 setup to autostart at boot

and started MM as part of the installer script…

that first start of MM took 33 seconds (stopwatch timing)
with MM running memory usage

               total        used        free      shared  buff/cache   available
Mem:             426         152         109          24         164         191
Swap:            871         179         692

so MM is 42% over the base memory on Bullseye 32 bit
system is responsive

[wyovino]

@sdetweil I appreciate your efforts with this. After a week of trying everything to make it work on Bookworm I gave up and built it on Bullseye. I had a couple of issues though. The automatic install script froze the system during the Node installation. I had previously expanded the swapfile to 1024 (1 gb) as I found that the default setting was too low.

I removed MagicMirror and all of it’s sub directories and followed the manual install instructions. The mirror is now running well except for the MMM-Jast ticker which is now not nearly as smooth as it was under the previous version of MM running on Buster. I tried adding export ELECTRON_ENABLE_GPU=1 to my mm.sh script but that completely distorted the display.

I’m not sure if I’m going to keep this new version.
