> If so, it won't really be pin compatible.
There are more differences (e.g. number of SerDes lanes, number of PCIe controllers) as outlined by me in my original posting
back then. http://www.freescale.com/files/training/doc/dwf/DWF13_APF_NET_T0560.pdf (also linked to back then) shows even more differences on page 11 (albeit that's still with 2 SATA controllers on P5040/P5021).
You are correct that pin compatibility is not 100% which means that while designing a common board for both is perfectly possible it would require some compromises to be made. If one can live with the compromises, then a common board can be used for both P5020 and P5040.
Like settling with the lowest common denominator in those areas, like only having 1 SATA, etc. However, AFAIK the "X5000" has 2, so they obviously didn't do that...Quote:
If not, the board design must be slightly altered for the P5040.
Even if they don't have to start from scratch (far from it), it would still mean going back to the drawing table to design, prototype and test a de facto new/different motherboard. This could be time consuming and since they will pay a commercial company for doing all this and for all their "man-hours" put into the work, it will add cost that may very well be quite noticeable on the consumer end price for an extremely low volume piece of HW like this will be.
That was not the plan. The plan was to have one motherboard design, and then simply put one of the two pin compatible CPU chips in it, in order to create two "different" product options, with no extra cost other than for the other CPU.Quote:
> Maybe this will affect availability of a potential future 4-core version of the "X5000"?
It may be that the Cyrus Plus boards will be slightly different for P5020 and P5040 in order to make the best of both SoCs and not restrict the capabilities of any of them.
I think it may be quite probable that the 4-core gets cancelled altogether. The "X5000" is very expensive as it is, and upping the price tag even more just to gain two additional cores that will never be used in an Amiga context seems weird. So I don't think it will happen...
MorphOS is Amiga done right!
MorphOS NG will be AROS done right!
