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 .

I2C in Centos 7
by cjvijf＠gmail.com 29 Jan '17

29 Jan '17

Hello, I am running Centos on a raspberry pi 2b. (I downloaded the image from: http://people.centos.org/hughesjr/armv7hl/rpi2/images/ rpi2-centos-image.img.xz ) and installed the i2c libraries and modules for i2c. [root@rpi2-2 ~]# lsmod | grep i2c i2c_bcm2708 5006 0 i2c_dev 6027 0 From what I read that should be correct device file is there too: crw------- 1 root root 89, 1 Dec 31 1969 i2c-1 kernel: Linux rpi2-2 3.18.14-v7+ #794 SMP PREEMPT Sun Jun 7 12:50:51 BST 2015 armv7l armv7l armv7l GNU/Linux However, when I scan the i2c bus with 'i2cdetect -y 1' I don't see any devices (and I tried 2 that I know work). is the I2C stuff in this kernel working? (or is there a newer kernel version?) thanks, Ron P.S. I know this is an arm-dev list, but figured the I2C topic would fit better here than in a general Centos list

Pine64 Support
by Mike Calderwood 03 Aug '16

03 Aug '16

Hello all. I was hoping to get some information about how to get CentOS up and running on a board that is not yet on the supported list. I have a brand new Pine64 ( https://www.pine64.com/ ) that I'd love to have CentOS on if possible, so I figured I'd give a go at getting it up and running. And if I can help give back to a project that I've grown very fond of over the years, even better. That's the good news. Now the bad: I have basically no idea where to start. I have zero experience with ARM besides taking existing SD card images and flashing them on devices like a Raspberry Pi. I'm also not a kernel developer or anything else wonderful like that (though I am a software developer by hobby and trade). I apologize for requiring so much hand-holding, but hopefully I can make something resembling progress with enough assistance. If anyone can point to some good resources to give me a basic understanding of what I need (which will tell me if I'm even in a position to do this in the first place), I'd really appreciate it. Thanks for the help and for all the great work you've all done already! Mike

Openstack Repository?
by Gordan Bobic 24 Jun '16

24 Jun '16

Hi, Is there an early build / unofficial Openstack repository for aarch64 CentOS 7? I would rather like to try it on ARM, but would prefer not to go on a build spree to build all the packages myself fixing any bugs along the way if I can at all help it. Many thanks. Gordan

new aarch64 dev board "coming soon"
by Jim Perrin 22 Jun '16

22 Jun '16

There's a new board coming around october-ish according to their presentation at OPNFV summit and their website. From what I can make out, it doesn't appear to be fully SBSA compliant, but it appears that it *should* work with very little modification. I'm not making any promises though until I have a chance to get hands-on with it. If you're interested -> https://www.solid-run.com/product/armada-8040-networking-community-board/ -- Jim Perrin The CentOS Project | http://www.centos.org twitter: @BitIntegrity | GPG Key: FA09AD77

CentosArm Kernel
by OM Ugarcina 21 Jun '16

21 Jun '16

Hello Guys, I have a question on the roadmap for the CentosArm kernel . One of the reasons why people love Centos is the fact that it enjoys a longer support cycle than other distributions , which force the user to upgrade the whole OS every 6 months . But at the same time Centos backports important fixes , and improvements to the kernel to keep it up to date . So having a long term OS combined with kernel that is maintained is a very good reason for using Centos . So I wanted to ask : What is the strategy for the arm kernels , is there going to be an active program to maintain the arm kernel ? I know that the regular Centos kernel is not viable for arm , it lacks a lot of support for arm hardware . We need a more modern version that is still long term supported but newer . My suggestion would be to take kernel 4.4 as the Centos arm main kernel . It has support for arm basic hw , and it is compatible with driver source code that is needed to be added for boards such as bananapi R1 (or also known as Lamobo R1) . I my self am using Fedora's 4.4 kernels made for the fc22 line , but am expecting soon for that to disappear once fc24 comes out . And then no more kernel updates from fedora . Best Regards Milorad
