Hi all, I'm evaluating the Yosemite 440EP board at the moment, with the intention of using it on custom compactPCI boards. I've got a few questions to ask the group, but I'll leave those for another email.
In the final system, the cPCI host will be an x86 CPU (since I already have them), and the cPCI peripherals will be the 440EP custom boards --- so my intended target for the 440EP is as a peripheral, whereas the Yosemite is a host-only development platform (but, still I have a lot to learn, so its a good place to start). To help with the development of PCI drivers, I was thinking of getting a pre-existing 440-based cPCI board. I haven't found any 440EP boards, but there are a few 440GP and 440GX boards out there. I need the 440EP FPU in the real system, but for driver development, one of these machines would do. So I have located a few boards, mostly designed as PMC carrier baseboards. Has anyone used these? Actis computer CSBC-6440 440GP Momentum Computer Civet-C 440GP Extreme Engineering XChange1100/2/4 440GX Since these boards are designed as carrier boards, they all use a 21555 transparent/or non-transparent PCI-to-PCI bridge. I was planning to connect the 440EP directly to the cPCI bus (or at least via 3.3V/5V buffers), so the driver designed against one of these carrier boards would not quite be identical (since the host would talk to the 21555 bridge, not the 440 bridge). So, I might not follow this route. Alternatively, I could use a PMC, or PrPMC board, and develop the drivers that way, eg. Extreme Engineering Xpedite1000/1 440GX Artisyn Technologies PmPPC 440GP So - anyone have a favorite? Cheers Dave Hawkins Caltech.
