Project status

Hello. I'd like to know what is the status if arm-dev project? I recently bought A20- OlinuXino-MICRO board (https://www.olimex.com/wiki/A20-OLinuXino-MICRO) and successfully run it with their official Linux image. But it's Debian... I don't have any experience in porting Linux to other architectures and configuring for particularly board but i'm eager to learn it (i plan to use some kind of embedded computer to develop home automation system). Could you point me into right direction - how to begin and what should i know (i've been compiling kernels some time ago but i can't say i'm a kernel hacker). I would like to use CentOS for my purposes (i have some more ideas for small appliances and they are mainly ARM-based i think). Thanks for any help and information. -- Over And Out MoonWolf

Kernel questions
by Robert Moskowitz 02 Dec '14

02 Dec '14

Both my Fedora 19 & 20 remixes have 'static' kernels. What I mean by that, is when I do a yum update, I have to --exclude=kern* or I have an ubootable system. And that is not enough as you really have to work at it with some packages referencing the newer kernel rpms. In Fedora 21 they have a current kernel that works on a lot of boards. So the question for you people that understand kernels (which I do not): Is it possible to take the Fedora 19 kernel and get it working for all boards? or Is it better to take the Fedora 21 kernel and backport it to F19/Centos7? or A kernel is really a kernel and the Fedora 21 kernel will work just fine with Centos7-arm. After uboot and kernel, it is 'just' a matter of recompiling stuff for arm. Noarch rpms can just be moved over; or else they are really not noarch... Note that for my epel6 needs for RSEL6, I took a number of noarch rpms from the epel6-i386 repo and locally installed them to meet some messed up versioning challenges I had for my mailserver.
