Gigabyte MP30-AR0
by Gordan Bobic 03 Oct '25

03 Oct '25

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

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.

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?

Weird issue with NFSv4
by Stephan Guilloux 19 Mar '19

19 Mar '19

Hi there. Strange issue with NFSv4 this morning. RPI3b+ with kernel 103 and fresh yum update, set up as NFSv4 client. Trying to copy a whole folder with a few GB (many .rpm & .tgz and a few .img), from NFS mounted source to local filesystem. (cd /shared.nfs ; tar c) | (cd /local ; tar x) After a while ... - PING to the RPI works. - SSH sessions got frozen and login is impossible, even with USB keyboard on the RPI. - Sometimes, I do see some kernel backtrace on the VGA, but not always. As I have to switch off the RPI, there is nothing left in /var/log/message when system is back. If I do this copy with full SSH, the copy works perfectly well. (ssh xxx "cd /xxx ; tar c") | (cd /local ; tar x) I have the feeling that the system hangs often on the same huge file, but when I do copy it manually, even in a loop ... nothin happens. Any idea ?

Re: [Arm-dev] CentOS 7 KDE on Pi 3B+ video issue - strange
by kht-lists 17 Mar '19

17 Mar '19

I hope I am replying in the proper way. I am not very familiar with using mailing lists. Please allow me extend my thanks for the replies to my original post. I do have a couple of extra adapters. I seem to loose them or give them away that is why I purchased a couple more. I burned a CentOS Gnome image to a new SD card and tried it. Same issue as with the CentOS KDE image. I have installed the new, problematic ones on an Intel based PC and a Pi running Ubuntu. I now have 3 which will work with CentOS or Ubuntu or Raspbian. Ken p.s. On another list I have used I would get the individual replies to my post to which I could reply. On the Adm-dev list I get only Digests. Is there something I need to change in my account setup? It seems it would be easier to reply to a reply.

CentOS 7 KDE on Pi 3B+ video issue - strange
by kht-lists 17 Mar '19

17 Mar '19

I downloaded the referenced image a couple of days ago, burned it to a 16 GB SD card and booted my Pi 3B+. Fantastic! The Pi was connected with a HDMI to DVI cable to a Dell 19" monitor. I received in the mail a couple of HDMI to VGA adapters. The $4 generic ones which are all over ebay. I have several which I have purchased over the years and the generally work fine. [adapter.png] I decided to test the new adapters with the Pi. I connected one to the Pi and to a VGA cable to the same monitor (which has two inputs). I had NO video. No rainbow screen, no 4 raspberries screen, not test. Same for the second adapter. I tested the adapters on an Intel based PC. They worked fine. But it gets stranger... I booted the same Pi, same new adapter, connected to the same monitor from an Ubuntu SD card. The video was fine! And stranger still... I tried 3 older adapters with the Pi, CentOS and the same cable and monitor. The video was again fine! These adapters have no manufacturer markings. They probably all came from the same factory in China. Obviously something changed in the devices and I do not expect to ever be able to figure that out. However, something is also different in the video (driver I guess?) signal from the Pi with CentOS vs. Ubuntu. Can someone shed any light on this mystery? TIA, Ken Sent with [ProtonMail](https://protonmail.com) Secure Email.

raspi kernel upgrade activates not the latest kernel version
by Thorsten Holtkämper 17 Mar '19

17 Mar '19

Hi all, kernel upgrades on the raspi sometimes end up with not the latest kernel being "activated" in the /boot directory. The reason for this is the kernel rpm postuninstall script of the old kernel that is removed: postuninstall scriptlet (using /bin/sh): cp $(ls -1 /boot/kernel-*-*|tail -1) /boot/kernel7.img cp $(ls -1d /usr/share/raspberrypi2-kernel/*-*/|tail -1)/boot/*.dtb /boot/ cp $(ls -1d /usr/share/raspberrypi2-kernel/*-*/|tail -1)/boot/overlays/*.dtb* /boot/overlays/ It chooses the latest kernel version with "ls -1 /boot/kernel-*-*|tail -1" which fails for kernel versions that have different number of digits in the version string, e.g. 4.9 and 4.14 or 4.14.91 and 4.14.103. An additional "sort -V" should fix the problem, i.e. "ls -1 /boot/kernel-*-*|sort -V|tail -1". What do you think? Best regards, Thorsten

make aarch64 EFI bootable iso problem
by 曹瑀宏 06 Mar '19

06 Mar '19

Hello: I'm trying to make a EFI bootable arm iso based on CentOS-7-aarch64-Minimal-1810.iso. I extracted Iso and get the flie tree like this: . ├── boot.catalog ├── CentOS_BuildTag ├── EFI ├── EULA ├── GPL ├── images ├── LiveOS ├── Packages ├── repodata ├── RPM-GPG-KEY-CentOS-7 ├── RPM-GPG-KEY-CentOS-7-aarch64 └── TRANS.TBL Then I add my own rpms into Packages and repack the iso with shell command: mkisofs -o /root/myiso.iso -eltorito-alt-boot -e images/efiboot.img -c boot.catalog -no-emul-boot -boot-load-size 4 -boot-info-table -V 'CUSTOM CENTOS' -R -J -T . After that I burned the myiso.iso to disc, but I couldn't get the "EFI device 0" choice option on Arm Server's BootManager while the CentOS-7-aarch64-Minimal-1810.iso was OK, I don't know what's the problem and how to make a cutomized iso which can be recognized as a EFI device on ARM Server? Thanks!
