PI5 with ubuntu noble support

ZYMKEY4 Getting Started
1

Hi,
I am trying to install the zymkey on my PI5 running ubuntu 24.04 (noble), without success.
The pairing does not complete, the light stay blinking in high frequency.

The zymkey itself is working. I tried it on a PI4 without issues.
PI5 with raspbian is also working.

I looked into the install script and there seems no support for noble.
I added ‘distro = “jammy”’ to the script, but this doesn’t fix the issue.

Does anyone else already tried the zymkey on PI5 - noble?
Is there any timeline on official support?

Thanks!

Thanks for asking the question! At this time, Zymkey is only supported on Ubuntu 22.04, not 24.04. Unfortunately, the Pi5 does not support Ubuntu 22.04, so at this point your only choice is to run Raspberry Pi OS Bookworm (64bit) on the Pi 5 in order to support the Zymkey.

Hi!
Thank you for the reply.
Do you have any idea when ubuntu 24.04 LTS will be supported by zymbit?
Is there a way I can make it work from my side with some tweaking?

Hi @bert,

At this point, I do not have any sort of roadmap to Ubuntu 24.10 LTS support for Zymkey.

I have made several attempts myself to get the Zymkey working on Ubuntu 24.10 and have so far not had any luck.

Are there some specific features of Ubuntu that you require?

Hi,
We have a project running on ubuntu 24.04.
We need the PI5 for the extra processing power, and company policy obligates me to use ubuntu LTS versions.

I did some digging.
It seems the zkifc library is using sysfs to communicate with the gpio pins. I found some references towards “/sys/class/gpio” in the code. This directory is removed from kernel 6.6 onwards.
Sysfs is deprecated since kernel 4.x and removed from 6.6.
I think this is something that should be fixed in the sourcecode.
I tried some emulation of old sysfs, without success.

Kind regards, Bert.

Thanks for digging into this! Let me chat with the Dev Team and see what we can do.

@bert - You are correct in that /sys/class/gpio is no longer there in 24.04, so pointing at jammy won’t work. We are looking into it.
