>If you use a new PPc SOC like the T1020/40 you can use 4x PCIe for the graphic card and x1 PCIE for SATA / SOUND / USB3.0.
There are several option how to configure those SoC. my configuratioA is to use PCIex4, PCIex1, mPCIex1, mPCIexi/SATA, SATA, 1Gb directly from SoC my configuratioB would use PCIex4, PCIex4, 1Gb from SoC (it is not yet clear to me if 1Gb ethernet resserve one of the 8 available serdes lane, their early configuration matrix/table leaves this matter open)
There are advantages and disadvantages in both configurations. -Big advantage in configuration B is that then the motherboard would be compatible also with T2081, offering 43000MIPS + Altivec. (T1042 is roughly 16800MIPS) -configurationB would also make the basic board simpler (UPDATE)
>There are 2 SATA Ports on the T1040, but I think it is better to use a PCIE -> Sata card , because it is faster and it frees an additional PCIe 1x Port.
IIRC, the SATA is generation 2. So, it's fastest that our niche supports, but not if we can not master it's DMA function.
>I don´t understand your question. If configuration 2 is to be used. BETATESTER release can be made with only SD or USB as masstorage, but better I/O solution must be developed to the second PCIex4 port.
One way would be to use southbridge chip that offers everything from one component.
Another way is to use switch/bridge to split the PCIex4 to multiple PCIex1&PCI and use SATA, audio etc. components on those split buses.
UPDATE: T1042 and T2081 compatibility matters... these came up from google: http://cache.freescale.com/files/training/doc/dwf/DWF14_APF_NET_T0457.pdf (april 2014) http://2014ftf.ccidnet.com/pdf/0140.pdf (may 2014) Last edited by KimmoK on 28-May-2015 at 10:25 AM.
