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.

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?

Gigabyte MP30-AR0
by Gordan Bobic 12 Nov '19

12 Nov '19

Hi, I am toying with the idea of getting a Gigabyte MP30-AR0 board (despite the insanely exorbitant price tag). Has anyone got the aarch64 CentOS working on one of those? Any special instructions? Also, if I get the ISO, is it bootable on aarch64? Does the installer work? Or does the image have to be used like on 32-bit ARM? Thanks. Gordan

Interesting. I don't see any info on how to disable NEON, though, only an insinuation that there is a way.

Is there a rpm-ed Chromium package? Has anyone managed to get this to build on armv7hl recently?

Xorg Segfault, Firefox Illegal Instruction
by Gordan Bobic 29 Jun '19

29 Jun '19

I took the CentOS 7 arm32 image for a spin today and ran into some issues. Is there a bug tracker that anyone pays attention to for semi-supported altarch like armv7? I'm using a Tegra 2 based system Issues: 1) Xorg segfaults while probing platform, according to the logs. Only solution I have found is to create a new .repo file for CentOS 7.5 and downgrade xorg-x11-server-Xorg to 1.19.x from CentOS 7.5. 2) Firefox 60.x dies on startup with an Illegal Instruction error. FF 52.7 from CentOS 7.5 works. Is anyone working on either of these? I think the former affects more than just ARM. Gordan

Old dtb directory not deleted

I just did an update that installed a new kernel. All the old kernel files were deleted from /boot except for the dtb directory. In this case, dtb-4.14.82-201.el7.armv7hl Here is a list of the /boot directory.
