RACHEL-Pi on the Pi Zero 2

giakonda · May 21, 2022, 4:01pm

I have tried to install the latest image onto the Raspberry Pi Zero 2 but I fail every time!
Has anyone else had experience of this?

jamesk · May 21, 2022, 7:03pm

They have been out of stock here since release so I haven’t been able to get one to test with. What errors are you seeing?

giakonda · July 2, 2022, 2:44pm

Thanks James, No errors as such it just fails to load. I have tried 2 just in case the hardware was the issue.

jamesk · July 3, 2022, 10:24pm

Hi Howard. From the official RaspiOS page it looks like the Pi Zero W 2 requires a 64bit OS. It may even require the latest one. The 64bit RaspiOS hasn’t t been great in the past, but maybe it’s better now.

I will make a new image soon. The last time I tried to make one was in February and there were issues with some packages in the latest OS that were causing the SSID not to broadcast. If that’s fixed a new version can be released.

giakonda · July 4, 2022, 7:44am

As usual thanks for your hard work James, really appreciate it

racheljr9 · July 6, 2022, 2:42am

Let me know. I have a Zero W2 standing by for testing. Not rushing you! Just happy to help as a tester if you need one.

I am demonstrating Raspberry Pi in Zambia on the 3rd of October.
Has development of RACHEL-Pi stopped?
Should I just use Kolibri on the Pi?

jamesk · September 22, 2022, 10:26pm

Hi Howard,

Development has not stopped, but each new release of the Raspberry Pi OS since the last RACHEL image release comes with a bug that hinders SSID broadcasting for WIFI hotspots. They also have had driver issues that allow for less WIFI clients, so it has not been beneficial to update for some time.

During the time since that last release over 120 Kiwix modules have been updated, with new modules being added, which is where the focus generally is. Those are all still compatible with the available images.

Are you looking for a new image just to support the Pi Zero 2?

giakonda · September 23, 2022, 7:29pm

I wanted to be sure that I didn’t continue with R-Pi if it was not being worked on. I have installed. Kolibri on its own on the Pi 4 and the Pi 400. The only issue with the PiZero2 is the shortage, but I have been told by the foundation this will end in October . I was hoping that the moodle and the email facility might have been working.
As usual thanks for all the help and work you have put in to this, I do appreciate it.
Kind Regards Howard

jamesk · September 24, 2022, 12:21am

Hi Howard,

Understood. There are no plans to ever stop development of RACHEL-Pi. I can’t say for sure, but DataPost may be part of RACHEL-Pi in the future. It depends on the result of extensive testing and would be a decision by the team.

Moodle will most likely be in the next image as it is working. There is a bit of a hiccup around needing to register an email before finishing the setup…

I will look into the September 6th RaspiOS more and see if I can get you a new image before you do your demonstration.

James

giakonda · September 25, 2022, 7:51am

Thank you James that would be great. Again thank you for your help
Kind Regards Howard

jamesk · September 26, 2022, 8:02pm

Hi @giakonda - I worked on the new RACHEL-Pi image this weekend. The good news is there’s an image for you to test. Download and notes about it are below

Download

RACHEL-Pi 32bit Download - rachel_pi_09_25_2022.zip

Notes about the image

The incorrect syscall in the dhcpcd package that was causing the SSID to stop broadcasting is gone on the September 6th RaspiOS which is great news.
I can’t confirm how stable the default wifi driver is or how many clients it can handle right now, but it does seem to be working.
Moodle is installed. The default moodle login/password is admin/Rachel+1
I can’t be certain if the email configuration in Moodle works. Please test and let me know if it’s what behaviour you see around messages/accounts and I can rework it if it’s not working. Please change the default administrator email and password if you can.
The default system login and password for now is pi/rachel. Please change the password with “sudo passwd” if you’re going to bring this device online. The Raspberry Pi Foundation want to do away with default passwords and we should help with that if possible. I will come up with a better solution in the future.
Statistics now use GoAccess
Wifi can be turned on/off from the hardware page
64bit image will be made if the 32bit one is stable

=====================================================

Hopefully everything is working but please let me know if you run into any issues.

@racheljr9 you mentioned you’d like to test. Hopefull you can help test some of these features on this image.

James

giakonda · September 28, 2022, 10:57am

James you are a genius! Thank you so much for your efforts.
I’ll let you know how it goes. Wendy will do the work, wife of 52 years
I’m having chemo so they wont let me travel outside the uk
Thanks as always for your great help
Kind Regards Howard

giakonda · September 28, 2022, 3:34pm

Hi @jamesk, as you might guess I couldn’t resist trying it on the first machine to hand, it was a Raspberry Pi 3B, yes not the best! However I had an old laptop with the latest version of Pi desktop. First thing I liked it installed using the Pi imager, perfectly.
I have downloaded several Rachel modules with no glitches. I also setup Kolibri and added the usual suspects with no trouble.
I had to use a router because the WiFi didn’t turn on but that was no issue for me, I used the router WiFi and the Pi IP-address.
I will test it on the Pi zero2W and the Pi 4 later
thanks a bundle for the work you have put in, it really helps.
Kind Regards
Howard

racheljr9 · September 28, 2022, 9:01pm

Awesome! Downloading the image now. I’ll try it on my Zero W 2 first.

racheljr9 · September 29, 2022, 1:09am

I’m seeing the same issue(WiFi) with the Zero W2. It seems to work pretty well on the PI4 so far.
@jamesk
I’ll do some more testing tomorrow and try to kick the wheels a bit.

jamesk · September 30, 2022, 5:02am

Howard, I’m so sorry to hear that you’re going through chemo. Please know that we are all thinking of you as you go through this. You have been a major part of this community for many years and we all appreciate the time you spend helping others. If there’s anything I can do please let me know.

Congrats on 52 years of marriage! That is amazing. If Wendy ever needs help with anything or has any questions she or anyone else you work with can reach out direcly to me via email at james@worldpossible.org as well.

jamesk · September 30, 2022, 5:03am

Thanks @racheljr9 and @giakonda for the feedback on the image and Howard, no need to thank me at all, I love knowing it’s getting used in places that need it.

It’s too bad that WIFI didn’t work right away on the 3B, but I know there is a workaround. If it’s important to have 3B support with this image right away I can make some adjustments to get it working. I built this image using a 4GB Pi 4 board as I haven’t been able to get a Pi Zero 2W yet.

Just reading what @racheljr9 said about the 2W, I wonder if maybe we can find out what’s going on. Here are some commands that maybe @racheljr9 can provide the output of.

sudo systemctl status hotsapd
sudo systemctl status dnsmasq
sudo systemctl stats dhcpcd ( I think dhcpcd or dhcpcd5 )
sudo ifconfig
sudo rfkill list
and /var/log/syslog if it’s there.

I will make another image using the 3B as well for you to try just to see if the same issue persists on two devices.

James

giakonda · September 30, 2022, 6:02pm

Hi all, I’ve just copied a fresh image onto a Pi zero 2w and using a micro USB to Ethernet adapter turned the WiFi on and it’s working. also a quick look at Moodle and Kolibri and they are both working too.
I’ve not done much testing because Wendy is pushing me to get everything ready for her trip!
There was a small hiccup in that to get Moodle and Kolibri going a reboot was necessary but it looks good!

racheljr9 · September 30, 2022, 10:58pm

Still playing around with this build. Here are things you asked for. I’m assuming stats was a typo since it gave errors. I gave you the results for sudo systemctl status dhcpcd

I’m happy to help! I’m using a USB ethernet adapter.

sudo systemctl status hotsapd
