As my existing ARM systems are getting a bit ‘old’ – being based on armv5 (DreamPlug) or armv6 (Raspberry Pi) – neither of which is supported by the most recent Fedora release, I have been looking for an armv7-based system for further development and testing..
After some experiences with promising designs that have – sadly – failed to materialise, I decided on the ODROID U3, which is a quad-core armv7 system.
I ordered one – with usb/uart connection and fan-assisted heatsink – recently, and managed to get it up and running within a couple of hours with Fedora 19, using info from the Technoids site http://www.technoids.com/index.php/odroid-u2-fedora-install/
Next steps… Upgrade to Fedora 20, and investigate compiling a ‘newer’ kernel (currently running 220.127.116.11). Kernel source is available from GitHub https://github.com/hardkernel/linux/tree/odroid-3.12.y, but the newer kernels are – apparently – still a work-in-progress for U2/U3 support..
Fedora release 19 (Schrodinger’s Cat) Kernel 18.104.22.168 on an armv7l (ttySAC1) ................... $ uname -a Linux rgodroid 22.214.171.124 #1 SMP PREEMPT Sun Jul 7 00:41:00 BRT 2013 armv7l armv7l armv7l GNU/Linux
The system is sufficiently powerful that for the first time, kernel compilation on the device itself is a practical possibility, rather than cross-compilation…
