CentOS Linux on the Raspberry Pi 3
Contents
1. 32 bit Quick Start
- Download the official 32bit Image
URL : http://mirror.centos.org/altarch/7/isos/armhfp/ (check for Rpi3)
- Copy to sdcard
- We recommend a class10 or better sdcard with 8gb or more of capacity.
- unxz the image you downloaded above
dd if=CentOS-Userland-7-armv7hl-Minimal-RaspberryPi3.img of=/dev/mmcblk0 bs=8192; sync
- Boot your Raspberry Pi 3 :
- I've realised that this device will NOT boot from the usb power on a laptop ( my x1 carbon ), it does however boot from a wall plug that can supply 1.2A
- Connect the ethernet port of the device to a network that has dhcp capability
- power up the device, typical boot time is about 5 seconds from power up to having dhcp IP and login over the network
- You should now be able to ssh into your rpi3 as user : "root" with pass: "centos" ; please change this password straight away!
- The image comes configured with the default CentOS yum repos, and you should be able to do yum operations to add software and manage content. We are going to aim at a complete distro stack in the coming days, along with selected components from the EPEL repos.
Join us on the arm-dev list ( https://lists.centos.org/mailman/listinfo/arm-dev ) where we are talking about the user stories, the developer path and content for all our ARM support.
2. 64bit Quick Start
- Coming Soon
3. Hardware details
3.1. Hardware Status
Device |
Status |
Notes |
Ethernet port |
Works |
The default image with dhcp on eth0, this is the best route of entry to the new device |
HDMI Port |
Works |
|
USB Ports |
Works |
All 4 ports in the front are working |
Serial Console |
FAIL |
The 3 pin gpio hosted console did NOT work for me, needs verification |
3.2. Serial Console
You should be able to use a Serial USB cable ( also called a TTL Cable ). The pin out assignment needs to be :
pin |
role |
6 |
GND |
8 |
Tx0 |
10 |
Rx0 |
Do NOT connect the +5v cable that some of these serial cables also provide.
If you are using the AdaFruit ( or compatible ttl cable ) you can get the pinout details here : https://www.adafruit.com/products/954
3.3. Gpio Pin Out
A nice clear diagram with the details is available here : https://www.element14.com/community/docs/DOC-73950/l/raspberry-pi-3-model-b-gpio-40-pin-block-pinout
