Yes, but it may be better to wait when you're ready for launching the second CPU card project (ie probably after the first one is done or almost) so that you can work and lobby for a more up-to-date SoC to be used/usable...

That may change, as it needs only some license clarification on some published code from AW. And knowledge of the HDMI PHY model they used (which differs from the previous generations of HW).

[Arm-netbook] RAM
Hello, and apologies if this already has been talked about, I tried to find previous discussions on ML archives, elinux & rhombus sites. It looks like the DRAM will be standard DDR3, has low power DDR3 been studied ? Too expensive ? No available init code ? I ask because some other ARM boards differentiate themselves from the other one by using LPDDR3 and that has much better power consumption characteristics, and so do not heat as much. The regular DDR3 ones (in certain cases have a heat problem and have to be down-clocked to operate properly whereas the LP ones don't... On the same subject of heat dissipation, some boards use a layer of the pcb just below the soc to act as a heat spreader by having a copper area that is not used for signals, and it looks like this is effective, because other boards that don't have it endure heat problems. I had a look at EOMA PCB pictures, but I lack knowledge to definitely tell if there is such a copper layer provisioned.

Re: [Arm-netbook] Housing idea: screenless laptop

Re: [Arm-netbook] HDMI HEC on future boards
> it just never occurred to me (it definitely should > have) that that would result in potential "lock-in". I don't buy into this, there's no lock-in to me. The user will fill his needs whatever the mean, either by using something provided (almost) freely by the SoC, or by buying additional HW. So what can be argued is: will the few things added to every boards to provide the SoC specific functionalities be compensated by the things not needed for those who will get it anyways. That's a trade-of, additional price will also be a factor. But providing additional interface on the far end of the card is no philosophical problem to me. Especially for ubiquitous things like ethernet, I can't think of this being a locking-in feature. After all these boards are designed to have a long lifespan, so the need to upgrade is not as important. And if (and only if) a future upgrade does not provide it, then you always be able to switch to an USB one, if (and only if) you still need it... > i always thought, y'know, things like HDMI would be ubiquitous / > common enough that you would always be able to find an upgraded > computer card with USB-OTG and HDMI: the impact of specialisation at > the *user-facing* end never hit my tiny brain :) huh. In my computer life I've seen 2 wired net techs (BNC & eth), whereas I've used 5 for display (VGA, BNC, DVI, HDMI, DP). I'm OK with USB because of its backward compatibility (I'm still not sure it will stay that way) So I'm not sure trying too hard to guess the future is mandated here, just being pragmatic. Which I can (and have) be(en) convinced EOMA68 is... But I'm convinced that providing as much of the SoC functionalities as pragmatically possible is better. Either by enabling more widespread adoption, or by avoiding the need for USB-based addons. -- Vincent Legoll ___ arm-netbook mailing list arm-netbook@lists.phcomp.co.uk http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to arm-netb...@files.phcomp.co.uk

Yep, that's the one (thinkpad T42p) it was located just next to the webcam, over the display, angled towards the keyboard, with a slight overhang from the case, so that the led was not directly visible. It was switchable with a key Fn combo. Just ON/OFF, no real need for light levels. Real nice idea, before backlit keyboards... I'll take some closeup pics when I get back where it is stored.

In fact the question I had in mind was more: If there are such associated variants that can be (almost) drop-in replacement, but with backlighting...
