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

Kernel for BananaPi R1 (Lamobo R1)
by mo.ucina 12 May '17

12 May '17

Hello Guys, I have been compiling the Fedora 4.4.2-300 kernel for Centos , using the new Centos image for the Banana-pi . I have used the Fedora src rpm and then added the patch for the switch drivers specific for R1 (Lamobo R1) , then compiled it within the Centos dev arm environment I have . I ran into a couple of things : one cosmetic , the other one not so . Firstly the cosmetic one is that my packages came out looking like this : -rw-rw-r-- 1 user user 49332 Feb 26 07:27 kernel-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 87721969 Feb 26 07:27 kernel-4.4.2-300.LR1.el7.centos.src.rpm -rw-rw-r-- 1 user user 18785384 Feb 26 07:29 kernel-core-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 10452672 Feb 26 07:30 kernel-devel-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 1012496 Feb 26 07:27 kernel-headers-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 11844188 Feb 26 07:31 kernel-modules-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 925980 Feb 26 07:31 kernel-modules-extra-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 105452 Feb 26 07:27 kernel-tools-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 65356 Feb 26 07:27 kernel-tools-libs-4.4.2-300.LR1.el7.centos.armv7hl.rpm -rw-rw-r-- 1 user user 52160 Feb 26 07:27 kernel-tools-libs-devel-4.4.2-300.LR1.el7.centos.armv7hl.rpm They all have "centos" as part of the name , which I did not expect . I did not get that when compiling in Fedora. How do you remove that ? Second observation , a one that is a bit of a concern is that , after installing the new kernel I am missing bits : user@bananapi /boot $ ls -l total 43611 drwxr-xr-x. 5 root root 1024 Feb 25 22:21 38f5ec9e217b471e8adee477d933f640 -rw-r--r--. 1 root root 171924 Nov 26 00:43 config-4.2.3-200.el7.armv7hl drwxr-xr-x. 2 root root 15360 Dec 3 14:37 dtb-4.2.3-200.el7.armv7hl drwxr-xr-x. 2 root root 1024 Dec 3 14:47 extlinux drwxr-xr-x. 2 root root 1024 Jan 1 1970 grub -rw-r--r--. 1 root root 34922581 Dec 3 14:46 initramfs-4.2.3-200.el7.armv7hl.img -rw-r--r--. 1 root root 592347 Dec 3 14:37 initrd-plymouth.img drwxr-xr-x. 3 root root 1024 Dec 3 14:44 loader drwx------. 2 root root 12288 Dec 3 14:31 lost+found -rw-------. 1 root root 2879429 Nov 26 00:43 System.map-4.2.3-200.el7.armv7hl -rwxr-xr-x. 1 root root 5866104 Nov 26 00:43 vmlinuz-4.2.3-200.el7.armv7hl I expected that I would be missing 'initramfs' as the install prog is still work-in-progress. And I was prepared to create it with dracut . However I did not expect not to be missing all the other bits such as : config , dtb, system.map, vmlinuz . I did find my new kernel it was in that dir with a hex name : user@bananapi /boot $ ls -l 38f5ec9e217b471e8adee477d933f640/* 38f5ec9e217b471e8adee477d933f640/0-rescue: total 40652 -rw-r--r--. 1 root root 35427302 Dec 3 14:43 initrd -rwxr-xr-x. 1 root root 6033128 Feb 25 22:26 linux 38f5ec9e217b471e8adee477d933f640/4.2.3-200.el7.armv7hl: total 39995 -rw-r--r--. 1 root root 34923169 Dec 3 14:40 initrd -rw-r--r--. 1 root root 5866104 Dec 3 14:44 linux 38f5ec9e217b471e8adee477d933f640/4.4.2-300.LR1.el7.centos.armv7hl: total 41061 -rw-r--r--. 1 root root 35844934 Feb 25 22:24 initrd -rw-r--r--. 1 root root 6033128 Feb 25 22:36 linux So my question is how do I go from these 2 files above , to the situation where I can boot into the new kernel 4.4.2-300.LR1.el7.centos.armv7hl . Best Regards Milorad PS Once I have verified that the switch driver works , I will post it here .

Repo Error : [Errno 14] HTTP Error 403 - Forbidden
by Ramesh Tamang 26 Feb '16

26 Feb '16

Hello, It was fine yesterday. Today, I am having this issue. I tried with yum clean all but didn't work: [root@rpi2 ~]# yum install screenLoaded plugins: fastestmirrorc7buildroot | 2.9 kB 00:00:02http://armv7.dev.centos.org/repodir/c7-pass-1/repodata/repomd.xml: [Errno 14] HTTP Error 403 - ForbiddenTrying other mirror.http://armv7.dev.centos.org/repodir/comps/repodata/repomd.xml: [Errno 14] HTTP Error 403 - ForbiddenTrying other mirror. One of the configured repositories failed (comps), 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: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Disable the repository, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable comps 4. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=comps.skip_if_unavailable=true failure: repodata/repomd.xml from comps: [Errno 256] No more mirrors to try.http://armv7.dev.centos.org/repodir/comps/repodata/repomd.xml: [Errno 14] HTTP Error 403 - Forbidden[root@rpi2 ~]# Regards,Ramesh

FYI : yesterday outage and impact on publicly visible armv7hl build logs
by Fabian Arrotin 25 Feb '16

25 Feb '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Some of you probably already read this (see https://lists.centos.org/pipermail/centos-devel/2016-February/014432.html) but we had a big power outage in one DC where we have some services. While the initial mail mentioned only some public services, there were other services impacted by that outage. The armv7.dev.centos.org node is one of those. So I had to launch a restore process of the public content for rpmbuild (http://armv7.dev.centos.org/rpmbuild/) and repodir (http://armv7.dev.centos.org/repodir/) , so don't be surprised if that looks empty for now : restore process is still ongoing (and will take hours).

gui on Rasberry Pi 2 Model B
by johan.vermeulen7＠telenet.be 24 Feb '16

24 Feb '16

Hello All, i'm trying to get some gui on the Rasberry Pi. I ran : #yum groupinstall "Server with GUI" #systemctl set-default graphical.target I see no "X Window System" and I think some X packages were installed with the server with gui. Does anyone have this running? Many thanks. Johan

testing updated kernels - feedback wanted !
by Fabian Arrotin 23 Feb '16

23 Feb '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, With the recent CVE-2016-0728, I was quickly having a look at updating the different kernels we ship through the official images. Actually we only have two kernels : - - what I'd call the "generic" one (that can be used on multiple boards directly, and following the Fedora upstream kernel) - - the raspberrypi2 variant (built from sources located at https://github.com/raspberrypi/linux) I've built (and tested locally those myself) the following updated kernels (including patches for CVE-2016-0728) : - - kernel-4.3.3-200.el7.armv7hl.rpm (updating kernel-4.2.3-200.el7.armv7hl.rpm) - - raspberrypi2-kernel-4.1.16-v7+.1.20160125gitab2b2e0.el7.armv7hl.rpm (for rpi2, obviously, updating raspberrypi2-kernel-4.1.11-v7+.1.20151021git4047fe2.el7.armv7hl.rpm) One important thing is that actually we still lack an automatic update process, something I'd like to work (with you ?) in the following days/weeks. But you can already test the updated/unsigned kernels (feedback wanted !) - - create the /etc/yum.repos.d/ .repo file pointing to corresponding repo, depending on your board : - http://dev.centos.org/centos/7/kernel/armhfp/kernel-generic/ - http://dev.centos.org/centos/7/kernel/armhfp/kernel-rpi2/ as an example, here is how it would look like : [kernel-generic] name=armhfp kernel generic baseurl=http://dev.centos.org/centos/7/kernel/armhfp/kernel-generic/ gpgcheck=0 enabled=1 or [kernel-rpi2] name=armhfp rpi2 kernel baseurl=http://dev.centos.org/centos/7/kernel/armhfp/kernel-rpi2/ gpgcheck=0 enabled=1 - - now "yum clean all ; yum update" - - as the current call to "/bin/kernel-install add" (from systemd shipped with CentOS 7) doesn't cover - in the whole chain- armhfp, one then needs to build the initramfs + modify boot config rpi2 : - dracut /boot/initramfs-4.1.16-v7+.1.20160125gitab2b2e0.el7.img 4.1.16-v7+.1.20160125gitab2b2e0.el7 - systemctl reboot generic : - dracut /boot/initramfs-4.3.3-200.el7.armv7hl.img 4.3.3-200.el7.armv7hl - edit /boot/extlinux.conf to modify the kernel/initrd - systemctl reboot Thanks for the testers, and after we can edit the wiki page, and start working on a script that would automate all that.

FWIW -- I received a MP30-AR0 this week myself and have been trying to get CentOS 7.2 installed. https://wiki.centos.org/SpecialInterestGroup/AltArch/AArch64/Mustang, which is based on the same processor, says a UEFI bootloader is required. I tried following the instructions; now my server is a paperweight and I'm waiting to hear back from tech support.
