2nd day with C7 pre-alpha on Cubietruck
by Robert Moskowitz 23 Aug '15

23 Aug '15

So I see how little is there. Well at least selinux is running disabled, so I can move sshd to a different port without semanage. Since no ntp function, no date time update. Well this is pre-alpha. Speaking about pre-alpha and the status of the armv7hl development, now that AArch64 is launched, will effort be applied here? I have NO experience with github and have looked at the rbf information and don't have a cue how I can build any images myself. So I either need a lot of education, or some newer images for me to work with. And a repo of armv7fl rpms to work with! So any pointers would be appreciated.

armv7 kernel and uboot version
by Robert Moskowitz 22 Aug '15

22 Aug '15

I am asking this to find out what capablities I have for my Cubietruck. For example, there is a multiport sata card like: http://www.ebay.com/itm/1-To-5-SATA-2-0-Port-Multiplier-Card-3Gbps-SATAII-R… you can use. The otg usb port is almost working. And with patches (soon to be moved upstream) the wifi works. I see that the kernel I cannot get working yet is 4.2.0-0.rc2 (I have rc6 on f23a and still would need to patch that for wifi), but I can't figure out which uboot is on the image. Plus whatever is there was part of the pre-alpha, as my understanding, you would have to dd any new .bin to the boot SD card. Oh, also all you really need on the SD card is uboot. You can put all the rest on your sata drive. A USB drive does not work yet, but Hans says it would not be hard for someone that knows dracut to work that out and provide the instructions to get included upstream.

I installed Chrony and rsyslog, neither were in the minimal pre-alpha image. I see NTP starting and date is getting set. journalctl was already present thanks On 08/19/2015 04:48 PM, cc35359(a)gmail.com wrote: > Chronyd and rsyslog should both be available via the special yum repos > pointing to the plague builds, if they weren't in your base install. > You should also have the journalctl command at you disposal. > > > > > On August 19, 2015 11:42:53 AM CDT, Robert Moskowitz > <rgm(a)htt-consult.com> wrote: > > > On 08/18/2015 12:20 PM, Robert Moskowitz wrote: > > Since no ntp function, no date time update.

semanage error
by Robert Moskowitz 19 Aug '15

19 Aug '15

/etc/selinux/config has selinux as disabled and maybe that is why the error, but I would not expect that to be the cause... anyway: # semanage port -a -t ssh_port_t -p tcp 614 SELinux: Could not downgrade policy file /etc/selinux/targeted/policy/policy.2. SELinux: Could not open policy file <= /etc/selinux/targeted/policy/policy.29:y /sbin/load_policy: Can't load policy: No such file or directory libsemanage.semanage_reload_policy: load_policy returned error code 2.

dependency errors with installing ntp
by Robert Moskowitz 19 Aug '15

19 Aug '15

Not knowing what to install for ntp, I tried: yum install ntp* And got the following errors: Error: Package: ntp-perl-4.2.6p5-19.el7.centos.noarch (c7buildroot) Requires: ntp = 4.2.6p5-19.el7.centos Installing: ntp-4.2.6p5-19.el7.armv7hl (c7pass1) ntp = 4.2.6p5-19.el7 Error: Package: ntp-doc-4.2.6p5-19.el7.centos.noarch (c7buildroot) Requires: ntp = 4.2.6p5-19.el7.centos Installing: ntp-4.2.6p5-19.el7.armv7hl (c7pass1) ntp = 4.2.6p5-19.el7 You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest Just doing: yum install ntp got at least ntp installed. But afterwards: yum install ntp* still gets these messages.

dcfldd for Fedora 22?
by Robert Moskowitz 18 Aug '15

18 Aug '15

The rbf readme uses dcfldd in place of dd. Sounds interesting from what a search reveals, but I don't have it in any of my 'standard' F22 repos. Can I get it for F22?

armv7hl for Cubies
by Robert Moskowitz 17 Aug '15

17 Aug '15

For many reasons, I have been off this list for a couple months. My Cubies have been idle (except the few production ones). My like is beginning to get back in order and I would like to be able to block out a few hours a week working on Centos armv7 on either a cubie2 or cubietruck. I have seen a couple of notes about armv7-bananaPi support, but can someone either point me to builds I can use and instructions to get the system up and running, or tell me to go back to other projects for a couple weeks. thank you

CentOS kernel submission policy
by Vadim.Lomovtsev＠caviumnetworks.com 13 Aug '15

13 Aug '15

Hi all, We have some set of patches for our processor (Cavium Thunderx) and would like to add them to CentOS kernel for the time while they are being submitted into mainline. Is there any set policy for submitting patches to be included into CentOS kernel? And which kernel version/commit I should base my changes on? Vadim

Release for CentOS 7 on AArch64
by Jim Perrin 04 Aug '15

04 Aug '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 We would like to announce the general availability of CentOS Linux 7 for AArch64 compatible machines. This is the first major release of CentOS Linux 7 for ARM/AArch64 produced by the AltArch Special Interest Group. This release uses a 3.19 based kernel as well as incorporating fixes and updates provided through-out the beta process. This release is built from sources available at git.centos.org from the c7, c7-ppc64le, and c7-aarch64 branches. Installation ============ This release provides media for a network install, as well as an Everything ISO that can be used for USB based installation if desired. This ISO is currently too large for standard DVD media, and so is best used via USB media. Additionally, a compressed disk image has been provided for rapid deployments of a development environment. Downloads ========= Everything iso: http://mirror.centos.org/altarch/7/isos/aarch64/CentOS-7-aarch64-Everyth ing.iso sha256sum: 9294f741b4d63fd858e9234b86825fd214c1a86f91b9058d4d6440f96687a7a1 NetInstall iso: http://mirror.centos.org/altarch/7/isos/aarch64/CentOS-7-aarch64-NetInst all.iso sha256sum: 1cd1bab57dbc49d43efd5fe540e02147814e0facaaeae26e3bedf9a317d24d7a Disk Image: http://mirror.centos.org/altarch/7/isos/aarch64/CentOS-7-aarch64.img.xz sha256sum: 43930834944b3ac9c9348cc03ca1be215f5f96f3d6bd1a4100feaa34a92c1b69 Directions and Help =================== Hardware specific installation instructions can be found at http://wiki.centos.org/SpecialInterestGroup/AltArch/AArch64 Disk Image user/password information as well as the kickstart used to generate it is contained README at http://mirror.centos.org/altarch/7/isos/aarch64/ReadMe.txt - -- Jim Perrin The CentOS Project | http://www.centos.org twitter: @BitIntegrity | GPG Key: FA09AD77 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAEBAgAGBQJVwEPEAAoJEBbHyC76Ca13i4gQAMJ6K4Jaju0lbnLeLUqJN9xz 4cxqM3VH3rqkMSZVHFzJis5OID8Q1DTzKsaugSxWS/FNoG7xyl1HrHqfm8i5RLii WVZ9unxzJCIfMDPQ4Bd0AkkBgnNpFfI+0SZx1TWmbrNfcaN6qgQPzUHX03akBUh3 fSAsesMJy1WSEYz+mmStKercwJmO/bgbgQ5Y11cmcWo5S/OYBP87bpgJQCje7zUN lZDXG+pdpq+U801MeqpXNVqUazUFN7VuXq9p+8ZwTaw9gNdPIJpwBwM5YdptELSh 2q/ORbvT6s73FkFI0FNjEOzgbCUme47J4vvhvPOw8EksyuNVFQRoAaTLCf25wJTb VKm0ndnKMfnnjl/8+7cVkcGjJS0weavExTXqeYwxSb58jTn6E/aAa6yUj1XQkb2i AydUBLhPzpuhvxy/G6QLJMGVUZL/fe9g+4cbMFUatp0Vyrv2GlBeCAQTSEiq8puz 76ByH3z/aXkN8qkPmlQc9ruFYidlm6l5dWT4pws1KL6lWbRC10z+SD2TVTZ2A7Eq WE2KCvmFRL1ai2TzuIVF8WLUDtfT6P0ZzkH+guz01sCTq8GCaORyn3fX/hmnqn95 S5fAg+/IbEri4T/r84/Ervy9DekyZfGW2YTfHQX4Kp1fDd5AghYgmXAvIeAV6+Ke 4xMMY5b/TI1op1UigvYl =+QdN -----END PGP SIGNATURE-----
