How I got my Magic Mirror working on a Raspberry Pi 0 (zero)

Mikgabo

@greenwaydev I’m thinking you aren’t making the adjustment in the right location (possibly).

Try this from terminal:

sudo nano /boot/config.txt

and add the following to the file. Where you add it doesn’t really matter:

# Rotate display virtically
display_rotate=0

Mikgabo

@greenwaydev After you insert that text save it by ctrl + x, then y and enter

Mikgabo

the type the command:

sudo reboot

@greenwaydev Here is a great tutorial that can help you learn your way around MM.
https://forum.magicmirror.builders/topic/236/complete-setup-tutorial/6

I would recommend, once you get your MM configured the way you like to make a back up of it using win32 disk imager (make sure .img is on the end of the file or it won’t save as a disc image). That way if you mess up your SD card somehow you have a back up to use.

I used the image that was posted a few comments back. I can NOT for the life of me get the wireless to connect. I have followed every guide I can find and it will not connect. I have tried DHCP and static. I’m out of ideas.

@justindp2006 Had the same issue. Couldnt find the fix anywhere

Mikgabo

@justindp2006 so you followed the guide and entered you ssid and password?
You could try the terminal command

sudo raspi-config

And set up wifi via the on screen menu.

Failing that u could set up a wpa supplicant file and insert it in your sd card

Hope this helps

@greenwaydev sorry that post was kinda screwed as I made it on my phone the command was

sudo raspi-config

wed as I made it o

I understood :) I tried that earlier and again and there is no networking options under it?

Mikgabo

@justindp2006 try this out

Tried. Think it’s time to toss in the towel. Hours lost to this project. It would be one thing if I was new to all of this or ignorant to programming or pis in general. I just don’t understand and there are no clues. Thanks for the replies.

OK, so I haven’t confirmed it on this package but was having the SAME EXACT issue with an octoprint setup for my printer. Anyhow I ran sudo iwlist wlan0 scan and it sees my network. Here is the kicker though. My network shows up like "MyNetworkHere ". There is a space between MyNetworkHere and the ". I added the space, saved and rebooted and it immediately connected. Hope this helps someone.

I can’t get Magic Mirror to launch. Is this a problem with the scripts?

“How I didn’t got my Magic Mirror working on a Raspberry Pi 0 (zero) w”

tl;dr: My findings are that latest MM doesn't work on ARM 6 (Pi 0/1).

Hi all, I’m a Pi noob and I wanted to use my RPi 0w to put the magic in my mirror. I followed this guide but despite everything ‘apparently’ working, I only ever got a blank screen.

I followed this guide line by line (keeping same, out of date versions) I got warnings when installing MM but it installed however when Midori launched I only got a blank screen.
I followed this guide using Jessie lite but the latest l6 node version. Blank screen.
I tried on Stretch Lite with the latest l6 node… same problem. I even tried numerous browsers on Stretch as I read Midori had issues on Stretch. Blank screen.
I tested all the above by launching Midori with Google and that worked each time, the blank screen was only with MM.

I used SebTota’s image (link p9) and also had issues connecting to the internet. After bit of investigation I realised for me this wasn’t a WiFi issue (as others reported) but a Gateway issue even though it was set correctly in /etc/dhcpcd.conf

For those struggling with internet access, and if you can ping the LAN but not the internet, try this:

$ route -n

If the Gateway entry is 0.0.0.0 you have the same issue I did, correct it with:

$ sudo route add default gw 10.0.0.1

*(change the IP to your own router IP) then you should be able to reach the outside world.

This worked!!! However… SebTota’s image is now old and as soon as I connected to the internet, MM complains it’s out of date. As soon as you update MM, I got the same blank screen issue.

After hours of investigating and trying and trying again, I can only surmise that the issue is with the latest MM build
and that it’s just not designed for ARM6 architecture. It does however work just fine on my PRi 3B+ so there is definitely not an issue with MM!! It’s just a shame I can’t use the ultra small 0w to drive the mirror.

I’m no expert and this could be just me but I just thought I might share my findings in case it helps anyone else.

Hi,

Followed the instructions and could get it working neither with Midori nor Chromium.

I got error messages for chromium like this

bootstrap_helper: /usr/lib/chromium-browser/nacl_helper: Cannot open ELF file!  errno=2
[1:1:0509/144633.366460:ERROR:nacl_fork_delegate_linux.cc(315)] Bad NaCl helper startup ack (0 bytes)

[776:776:0509/144633.407424:ERROR:browser_main_loop.cc(272)] Gtk: cannot open display:

and i had also npm errors that I ignored

So I guess, as @Baldrick mentioned, that this is not working anymore :(

Will probably just get a R3B+ for that and keep the 0w for experiments.

@baldrick
After a fresh reboot and just after starting MM and getting a black screen.
Run with:
'cd $HOME/MagicMirror/installers/; pm2 flush && rm ~/.pm2/logs/mm-* ; pm2 start mm.sh

And make sure that your mm.sh reads:

cd ~/MagicMirror
DISPLAY=:0 npm start

Can you please (open a new issue on Github) and post the output of:

uname -a
dmesg -x -d -T
journalctl -b
sudo cat /var/log/Xorg.0.log
sudo cat /var/log/lightdm/lightdm.log
systemctl list-unit-files -t service -all
cat ~/.xsession-errors
cat ~/.pm2/logs/mm-error-0.log
cat ~/.pm2/logs/mm-out-0.log

Hello :) since my Zero’s USB port is broken, I have to run everything from ssh and scripts.

I experienced the same as @Hawking: when starting midori, the screen would either turn black or white. I installed chromium and replaced the line “midori -e Fullscreen -a http://localhost:8080” by “chromium-browser --incognito --kiosk http://localhost:8080”. Chromium only shows a line at the top of the screen saying it can’t be run as sudo.

Any idea on how to fix this? Or how to get midori to work?

Thanks in advance :)

Sorry for a stupid question, I’m all new to this.

When I ran the git clone command, I got this:

fatal: unable to access ‘https://github.com/MichMich/MagicMirror/’: server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none

Am I missing something?

Thanks

Edit: NM, found the problem. Date/time on the pi was wrong.

add --no-sandbox
for example - chromium-browser --no-sandbox --disable-infobars --start-maximized --noerrdialogs --kiosk --incognito http://localhost:8080

Thank you @NoNameRo !! It works now on Stretch. I can’t use localhost:8080 but xxx.xxx.xxx.xxx:8080 works fine.

Since initd is replaced by systemd, how do I run a script at boot up? For the last couple of days, I’ve been using a solution using pm2, but it seems to run the “node serveronly/” process multiple times so that my pi’s cpu has been at 100 % all the time.

Where do I have to place the script with
cd ~/MagicMirror
node serveronly &
sleep 45
sudo xinit /home/pi/chromium_start.sh
and how do I activate it for boot up?
