Cebit 2012, 06 to 10 March

Anyone going?

http://www.cebit.de/home

Maybe we can have some eoma68 cards ready to show by then.

Killer!

The Gx16 would be enough for me to transform it into a Server...
Unfortunately I have not found any prices...

Thanks, Greetings and nice Day/Evening

Mali at fosdem

The initial Mali code is at http://limadriver.org/

Lots of work to do but looking good so far.

 where?  can't see it! https://gitorious.org/lima but... no, no links
saying "git clone ...."

Re: EOMA68 pinout change may be needed

Hi, newbie alert (in this forum) so sorry if this has been covered.

Why not just use PoE ?
http://en.wikipedia.org/wiki/Power_over_Ethernet

Even if the host device doesn't use Ethernet, or the user doesn't have a PoE
switch, you can still use a 'power brick' to inject the power onto the Ethernet
pins.

Probably still makes sense to have at least one real 5v pin in any case.

 i'm inclined to say that if POE is needed, it should be on the
motherboard, even if that motherboard is about 56mm long and 25mm
deep.

 the reason for that is the extra cost of the components in cases
where POE is *not* required (or used) would potentially make a
mass-volume product uncompetitive or unprofitable.

 if it's actually in the _standard_ that POE is required (no,
standards *must* not have anything that is "optional" in them), then
that would potentially jeapordise the entire project.

 EOMA is about covering as much as possible with "Lowest Common
Denominator" interfaces that have downwards / upwards compatibility
built in to those standards, already.  so, yes, 10/100/1000 ethernet
is ok, because if you connect an 8-wire socket to a 4-wire plug (or
vice-versa), ethernet auto-negotiation kicks in.  likewise for SATA
and USB: the standards auto-negotiate the fastest possible data
transfer rate (yes i've explicity said on the standards page that USB2
480mb/sec *only* CPU cards are banned).

 surprisingly, the bar is extremely high (on the
Lowest-Common-Denominator) thanks to that auto-negotiation. but adding
things like POE?  naah.  can't do it.

Because

a) Requires a PoE source.

b) Requires a fairly tolerant DC-DC power supply to make useable
voltages out of it in a safe manner. PoE is by no means a clean and nice
power source at convenient voltage.

c) Requires an Ethernet jack. We currently have Ethernet on the EOMA
connector only.

5V DC input is much simpler to work with, and more readily available in
the types of components we work with here. I.e. the power management
chip companion to A10 has everything builtin for dealing with a
reasonably stable 5V power source such as USB.

Please note that there is nothing that stops building a chassis for the
EOMA card that accepts PoE and powers the card from it via a suitable
DC-DC converter to 5V.

Regards
Henrik
