centos 7 64 bit on raspberry Pi 3
by R 23 Sep '20

23 Sep '20

Hello, I was wondering if there is a procedure for installing Centos 7 on the Raspberry Pi 3 B+ while installing Centos 7.5 on armhfp is very clear and documented given that a raw root image is provided and you just "dd" it on the memory card, it is not clear to me how to do it with aarch64. A ISO image is provided but how to install it on the raspberry ? thank you Rick

epel-release
by Robert Moskowitz 30 Jun '20

30 Jun '20

Ok, I see this epel-release in the epel1 repo that I installed via the wiki. So I decide to install it, and it created an epel.repo.rpmnew file. I swicth around the files and try a 'yum update' and get: epel/armhfp/metalink | 47 kB 00:00 Could not parse metalink https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=armhfp error was No repomd file One of the configured repositories failed (Unknown), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: .... File /var/cache/yum/armhfp/7/epel/metalink.xml does not exist So I put everything back.

AArch64 Pi4 and CentOS 8
by Brent Kolasinski 18 Jun '20

18 Jun '20

Hi everyone, I've been looking into things I can do to help with getting CentOS 8 AArch64 to run on the Pi4. It appears that the upstream kernel now has the proper stuff merged in to support the NIC and eMMC controller. So far 2 approaches are being made: The U-Boot mechanism (looks like this is what Ubuntu 20.04 is doing) and the SBBR (ACPI + UEFI) way. It looks like a few folks may be loading the SBBR firmware with luck on the standard CentOS 8 aarch64 image. Could one potentially recompile the SRPM for kernel 5.6 from elrepo and drop it in? I found the CentOS8 pi4 aarch64 userland image here: https://people.centos.org/pgreco. Has anyone tried getting the SBBR firmware to load the stock aarch64 CentOS 8 image without support for the eMMC / NIC, to basically bootstrap and compile the SRPM for the 5.6 kernel? And finally does anyone know if CentOS will be backporting the Pi4 changes to 4.18, or will they be releasing a custom kernel? Could I help out with that?

bluetooth on CentOS Linux release 7.6.1810
by R C 31 May '20

31 May '20

Hello, I am going to use a raspberry PI for browsing on a TV, so I want to connect with a wireless keyboard, bluetooth. It looks like bluetooth is "not running"; [rocr@centos-rpi3 ~]$ systemctl status bluetooth.service ● bluetooth.service - Bluetooth service Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled) Active: inactive (dead) Docs: man:bluetoothd(8) I don't have any bluetooth devices connected yet. but the service should be up, right? Is there a write-up, guide, to get bluetooth configured? thanks, Ron

Re: [Arm-dev] Add Marvell Armada7k8k NIC (mvpp2) support patches
by Marcin Wojtas 26 May '20

26 May '20

Hi Jim, It's been a while, since I sent the patch. Any objections about merging? Is v4.11 kernel still a valid baseline or for the next releases or we should use v4.14? When is that transition and next release supposed to happen?

hi i couldnt find a search tool for the mailing list, so apologies if it has been already discussed but i cannot find a howtofor the orange pi pc2. i see it as a supported device but not sure what i need to do to get it to boot. i used rufus and install OS and tried: CentOS-Userland-7-aarch64-generic-Minimal-2003-sda.raw.xz CentOS-Userland-7-armv7hl-generic-Minimal-2003-sda.raw.xz CentOS-Userland-7-armv7hl-RootFS-Minimal-2003-sda.raw.xz and none of them boot. I am assuming i am to load the specific uboot for the said device but not sure how?

CentOS-arm on v5 Odroids?
by Robert Moskowitz 05 May '20

05 May '20

I have been off writing IETF standards (mostly for UA comm) for the past many months. But I just got some funding for an arm Centos project but it has to be a 5v (meaning armv7) system. Quite some time ago (a year ago, wow!) I worked on Odroid HC1. Has anyone worked with any Odroids recently? Or any other similar boards? thanks
