[ERROR] unable to write js/positions.js

Although it’s not related to your problem - I have a lot of trouble getting MM to run on the 512MB Pi3 A+.

It freezes often - possibly it’s bad h/w or sd card although it all tests fine - but after several days of running and it ends up frozen and inaccessible. (ie can’t ssh to it, etc unless I restart it)

I tried using some of the lower memory options instead of using electron without much success. It runs for a little longer but eventually still dies. None of my Pi3 B models with the 4GB RAM have had similar problems - so I tend to think it is something related to RAM

Just to say that you may find the experience in running on the Pi 3 A+ to be “complicated”

@emlowe what os level are you running?
i recommend the 32 bit legacy image

if you use my install script i will increase the swap spacr

@emlowe yes, i would try the 32 but legacy image on bullseye

bookworm seems about 500m bigger

[sdetweil]

@emlowe out of memory

I have had that problem before and it was a bad card. One other time it was a bad USB drive… Might try a different sdcard.

[sdetweil]

@plainbroke good point, I have had a number of sd card failures over the years, and they have all become read-only

Hello all,

So based on some of the comments here, i tried a new SD and a new pi. I had spare SDs lying around and I had a pi 4B that I was going to use initially but didn’t have a micro hdmi cable at the time so I had to use the 3. Micro HDMI cable came in, loaded piOS on the new SD, followed the MagicMirror install instructions and it came up first try.

Not sure what the initial issue was with the original install but I honestly just needed a win before getting bogged down in the weeds with stuff. I would like to have some fun with it first. Might go back to the original pi3 at a later date just to try and correct the initial issue, but for now, I’m happy.
The inital install, I had used sudo for the installation of MagicMirror, in this iteration I did not. I only utilized sudo to install the node.js

thanks everyone for the advice/comments.

@FalcoonnnnPUNCH IF you had used my install script it would have done all that for you

[sdetweil]

@FalcoonnnnPUNCH and sudo would have caused the prior problem. as the folder would have been write protected
