I have an application where I want to communicate with up to 20 cPCI slaves per cPCI chassis, where the slave devices each use a PowerPC based processor. (The masters happen to be x86 CPUs; because I have them). I looked at the 440EP using the Yosemite board http://www.ovro.caltech.edu/~dwh/powerpc_440ep.pdf and the Freescale MPC8349E http://www.ovro.caltech.edu/~dwh/powerpc_mpc8349e.pdf I had some trouble the with AMCC chips; the DMA controller operation was weird, and AMCC tech support was pretty much useless. Freescale's technical (design) support is great, and they (the software developers; Kim, Timur, etc) are actively maintaining/contributing to git trees for u-boot and Linux. If you can change processors, I'd recommend any Freescale part over an AMCC part. I'm working on a cPCI board design at the moment, you're welcome to look at the design; * PowerPC * Altera Stratix II FPGAs * dual 8-bit 1GHz ADCs http://www.ovro.caltech.edu/~dwh/carma_board/ Regards, Dave _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
