Hi,

Recently I came across this (Turris Omnia) bit of kit and I'm really considering buying one.

Provided that it has support for mSATA, you could plug some good SSD and don't bother with logs and downloads/shares wearing your main flash too quickly.

What do you think?

There's a lot of "blah blah" on all of these ARM devices.
The key question in my experience is: Is it entirely supported (drivers for the CPU and the embedded devices in the SoC, usually) in the kernel.org kernel? If not, when will it be?

If the answer is "not at the moment" and "Unknown", move on because you'll have a device that has a short life span: the device works with Linux version x.y.z and that's it. There's only so long you can be stuck on a particular version of the Kernel before you're forced to upgrade, which of course can only be done if there's support in the main line Kernel. I have seen too many projects have their own git tree where the support never gets mainlined.

Once it's supported, it's great :-)

Hi,

@drmozes Good points, I'm gonna pay attention to that.
Hell, I'm doing embedded Linux not from yesterday and I didn't think of those. Dumb.

@atelszewski,

I was also looking at the Turris Omnia router and stumbled upon this thread. Did you find answers to the questions that @drmozes raised ("Is it entirely supported (drivers for the CPU and the embedded devices in the SoC, usually) in the kernel.org kernel? If not, when will it be?").

Hi,

Nope, I haven't investigated yet. I'm planning to do so before the campaign ends, but can't promise I'll manage.

Well the SOC is a Marvell Armada 385 ... I looked in the newest longterm supported kernel (4.1.14) and could not find support for this soc in the obvious places ... but on more research (https://www.kernel.org/doc/readme/Do...Marvell-README) it looks like this sock is supported in the mvebu family (shows up if you enable multiple platform selection). But I've no idea how well that is supported.

@drmozes : do you still use sheva plugs ? if so on what kernel version ?
According to the readme above the kirkwood support is in mvebu too, I've not compiled kernel for my dockstar since 2.6.38 but a lot has changed since then. Maybe you happen to have compiled one for your sheva plugs with the new architecture branch mach-mvebu ?

-current runs on my Kirkwood machines with Linux 4.2.6. It's supported by CONFIG_MACH_KIRKWOOD which is under ARCH_MVEBU. However, these are armv5 machines so are handled by the 'armv5' kernel.


The Armada 385 is an armv7 and I don't have support for it compiled in to the armv7 Kernel, but I'm going to do a kernel update for -current soon so I'll add it into the next build. This will be SoC support, but I don't know what else it may require yet.
It looks like it'll be supported by Debian, so that's always a great sign that it'll actually *work* :-)
