. Sure there are now new affordable SoC options available even for small customers.
just curious as to what SoC's these would be??

"New" is probably pushing it. The affordable socs still use several years old tech, and are not _that_ big update from OMAP5just curious as to what SoC's these would be??
Mali actually has open source driver, which makes rk3288 quite appealing. However there has been threads past where this SoC has been discussed even by ED, and there are concerns.First things first, find a graphics subsystem that has open source Linux 3D drivers.
and there it is... lol
whats available and what ED would be willing to use as well as what the vendors will sell in a small batch limits what SoC's are suitable for the Pyra.
The CPU board can be freely redesigned, that actually provides a lot of freedom. The required feature compatibility is a rather moot point, I don't see an issue with that one. Modifying the main board for that purpose (e.g. adding some bridge chips/controllers) would actually be rather cheap and not too far off, either way - that's the advantage of using a simple dual-layer PCB. As long as everything else can stay the same...The new SoC has also to be nearly pin compatible, feature compatible, suitable for mobile device in therms of power consumtion, power dissipation, mechanical dimensions.
The OMAP5 was chosen because it was pretty much the only choice - mainly for other reasons. Our OMAP5 wasn't even designed specifically for mobile usage - that variant was never released.This is the reason why nobody can name a replacement for OMAP5.
I'm curious how the latest RISC-V will do with Linux. If the performances are there, the foss communities might build some nice stuff with it
The new SoC has also to be nearly pin compatible, feature compatible, suitable for mobile device in therms of power consumtion, power dissipation, mechanical dimensions. And the most important, it has to be significant better than the old one. This is the reason why nobody can name a replacement for OMAP5.
, and so far there hasn't been any compelling x86 chip, either.
I'm actually looking forward to the ultra low power chips that may follow Raven Ridge at some point.
Once they got the EXACT cause narrowed down and a solution in mind, all that should be needed is either retrofitting of the old boards, or (more likely based on what Nikolaus has been saying) a new board with redesigned traces. Proto that, test that, if it's all good, make it.
Cases can be made whenever, presumably once ED moves the molds.
I'd say 3-6 months, and that 6 is rather generous. I think it'll be more like 3-4 realistically.
So, your realistic 4 month are over. Where are we? Nearly almost there where we were 4 month ago and far far away from shipping.
RetrogamingWhere has all my time gone?
That sounds good. Make some noise about thatthe noise fixed main boards have arrived yesterday
Oh, we are?
Let me see... 4 months ago, we narrowed down the 4GB RAM issue but hadn't done any layout change nor Simulation to make sure the issue has been fixed.
The remaining issues of the main board and case also weren't fixed back then.
Now that has all happened and the CPU boards are already in production since a few weeks, the noise fixed main boards have arrived yesterday and the cases have received all fixes as well (though I need to receive them to confirm that).
Right, absolutely nothing has happened.
Oh, well, but then again, nothing has happened and the the last few years - because a few years ago, we also didn't have working boards or cases. Oh, we also didn't have them 10 years ago... Does that mean absolutely nothing has happened for the last 10 years?
Where has all my time gone?

While admittedly I hadn't factored in stuff like Chinese New Year adding further delays, this is about the speed of progress I expected, yep.Oh, we are?
