CentOS - Raspberry PI 4

... due to lack of internet. When I connected over ethernet, RaPi4 catched the correct time again. - Still wifi is missing.

Yes, the broadcom chipsets on the rPi do not appear to be supported in the latest update.

However, I can report that a USB wifi b/g/n dongle using the Ralink 5370 chipset *is* recognized and works fine, even if it's only 2.4GHz and 150mps capacity.

I also added a real-time-clock module (DS3231) to mine to get rid of the system clock problem when there is no internet connectivity.

I discovered this week that converting from CentOS 8 to CentOS Stream restored the WIFI support for the onboard chipset!

A co-worker pointed me at this page: https://ostechnix.com/how-to-migrate-to ... s-linux-8/

The basic steps are fairly straightforward; start by making sure you're up to date:

Code: Select all

sudo dnf update

(reboot)
The following steps should be done as root or with sudo

Code: Select all

dnf install centos-release-stream
dnf swap centos-{linux,stream}-repos
dnf distro-sync

reboot again, and the wifi drivers for the new chipset are active.

Thanks, Kevin, for this hint. This is a clean solution.

I was a bit surprised, switching to CentOS Stream, because the Userland image has already been entitled "stream" as far as I remember. But it works. And I am sure now having switched to stream.

Thanks again
Michael

I just started to use CentOS and discovered the image created by Pablo (https://people.centos.org/pgreco/CentOS ... Minimal-4/).
While that image loads perfectly fine, I am not able to run a simple `dnf update` command. I believe the issue is due to it being version 8, which reached end of life on Dec 31, 2021 (https://www.centos.org/centos-linux-eol/).

Is there an updated version for PI? Or has anyone been successful at upgrading to CentOS Stream 9 after installation?

Unfortunately CentOS Linux 8 of all flavours is dead and the repos have been moved to vault.centos.org. I am not sure if that includes the arm repos as well. You can check with a web browser pointing to it and then xref with your yum config files in /etc/.yum.repos.d to see the (probable) path you need.

Looks like Rocky have a working armv8 el8 distro though and converting to that would be considerably more likely to work than to Stream 9 (if an armv7 version even exists). The Rocky wiki https://wiki.rockylinux.org/en/special- ... spberry-pi has some info.

I'm interested in CentOS Stream 9 images for Raspberry Pi 4. Does anybody know the steps that @pgreco followed to create the older 8 image? Is this documented somewhere?
