rng-tools missing and /dev/hwrng without driver
by SW＠EU 31 Oct '25

31 Oct '25

Hi, today I will report a problem that is released to ipa-server. This server contains a certificate authority and such service need many entropy. The default on CentOS 7 on a Banana PI is not enough, i.e. $(cat /proc/sys/kernel/random/entropy_avail) is less than 1000. I have solved this in meantime by installing and enabling of haveged from the EPEL repository. Normally it would be done by installing the rng-tools. But there are two problems: 1. The rng-tools was not in the repositories, so I have downloaded rng-tools-5-8.fc24.armv7hl.rpm because this are the same version which is included in CentOS 7.3 for x86_64. 2. This rng-tools are usable but the daemon starts and stops immediately with the following error message: # rngd -v /dev/hwrng: No such device /dev/tpm0: No such file or directory No entropy sources found, exiting This is not the problem of this binary it is a problem of the Kernel. /dev/hwrng exists and if I remove it then it reappears after reboot, but # ls -l /dev/hwrng crw-------. 1 root root 10, 183 1. Jan 1970 /dev/hwrng # udevadm info -a -n /dev/hwrng Udevadm info starts with the device specified by the devpath and then walks up the chain of parent devices. It prints for every device found, all possible attributes in the udev rules key format. A rule to match, can be composed by the attributes of the device and the attributes from one single parent device. looking at device '/devices/virtual/misc/hw_random': KERNEL=="hw_random" SUBSYSTEM=="misc" DRIVER=="" ATTR{rng_current}=="none" ATTR{rng_available}=="" there is no driver for this device. I have searched and found this link http://forum.lemaker.org/thread-23618-1-1.html which includes a link to the full story. If I read all right then on bananian /dev/hwrng appears only if the adapted or a more actual sun4i-ss.ko module is loaded (there is written: "module author has indicated this will be going into the mainline kernel shortly“). This module is also loaded on a Banana PI with current CentOS 7. So does the kernel of CentOS 7.3 for ARM32 include this patch and if yes why it does not work or otherwise why this device appears but has no driver?

EPEL repo not available?
by Boyd Ako 31 Oct '25

31 Oct '25

Can anybody verify that the EPEL repo for ARMHFP isn’t available? I keep getting an error saying the REPOMD file isn’t there when running yum. It works if I use —disablerepo=epel\* when using yum. But, there might be some stuff in the EPEL that I’m looking for. Running it on a Raspberry Pi 3 and trying to get Nagios installed for home use. Domo, Boyd H.

Gigabyte MP30-AR0
by Gordan Bobic 31 Oct '25

31 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?

Odroid-HC1 came, but
by Robert Moskowitz 28 Nov '18

28 Nov '18

got myself an ODroid-HC1, but seems I forgot some things... Power supply! I have a right sized barrel to USB cable, but my Ankar is rated up to 3A and is fused at any draw above that. I remember looking at power supplies before, but can't find the link. UART to USB. The ones I have won't fit. They are for connecting to pins, not a connector like the HC1 has. What do I get? Plus what are the pin-outs? I really need to get a schematic for this... Case cover. For some strange reason, I thought it would come with a cover. I see now, that if you stack them you only need one cover, so it is most likely a separate order. The unit came with a small bag with 2 screws, but I cannot find any holes in the case for any screws! Strange. So after I get at least the power supply and UART to USB for console, I will be asking how to get this to boot completely from the HD like I do with my Cubies! thanks Bob

back at it
by Robert Moskowitz 22 Nov '18

22 Nov '18

Oct 27th I was the pedestrian in a pedestrian/auto accident. Healing well enough. PT for walking and that should correct in a couple weeks. Dislocated right shoulder and that is the real limiter for the next 4 weeks. Affects my typing and mousing. Plus for the work here, reaching for and doing all I do with my arm boards. Thus I hope now to spend some time on Centos/Fedora arm work, but reduced until the arm is out of the sling. Bob

Again, thank you for the effort! We would like to test them but they turn out to be opt-in packages; Looks like the %scl tag was not set during the build. Jumped to a wrong conclusion here, sorry for that. The spec in the source package is not converted for a sclo-build. Could someone reissue the build with the proper buildtag? Rephrase: Is it possible to reissue the build from a sclo enabled (remi safe) source package?
