Ten days ago I wrote an article here about an armv7hl test image for the Cubietruck 32-bit ARM board. I have just uploaded a similar armv7hl image for the Raspberry Pi2. Both of these images are created with the RootFS Build Factory (a 2015 CentOS GSoC Project from Mandar Joshi sponsored by the CentOS Project).
The Raspberry Pi2 image (as well as the sha256sums for the compressed and uncompressed images) is available here:
This RPI2 image actually uses the base kernel and boot files from the Raspberry Pi Firmware github site, and not the CentOS-7 armv7hl kernel. This RPI2 kernel seems to be causing an issue with firewalld, and one must edit the file /etc/firewalld/firewalld.conf and change the variable IPv6_rpfilter from yes to IPv6_rpfilter=no.
Mandar has been making lots of progress on RootFS Build Factory and other people have reported that images generated from RBF for Odroid C1 and Banana PI are also functional, as is the image for QEMU. I will be trying to obtain and post workable images from these boards soon.
I want to point out that the current images created are not signed and are taken directly from the output of our armv7hl builders 'as is' with no QA testing. The armv7hl build is still very much a work in progress and the image manifest is based on a CentOS-7 (1503) minimal install from our x86_64 install media. We have not yet completed the entire tree and the build repositories may at times NOT have complete closure and are only about 85% complete at this time. We will finish the baseline build and then start the updates repository, but as of now these repos should be considered PRE-ALPHA and not production ready.
To use this image, you first extract it with this command:
Then just dd it to an SD Card and boot it in your Raspberry PI2 using a command like this from linux:
dd if=./rpi2-centos-image.img of=/dev/mmcblk0
(Note: your SD Card device may vary .. you should be able to find the card device with fdisk -l )
If you are going to be at Red Hat Summit 2015 this upcoming week (June 23rd to 26th, 2015), please stop by the CentOS Booth in the Community Central area and we will have working armv7hl demos of a RPI2, Cubietruck, and Banana Pi .. as well as a working armv8 (aarch64) AppliedMicro X-Gene Server on a Chip demo machine. Hope to see you there.
