Dear all, I am using MPC8260 for ATM cell switching between FCC1 and FCC2.I have two UTOPIA interface connected,one each to FCC1 and FCC2.FCC1 is connected 16 PHY devices and FCC2 is connected 2 PHY devices.I have following questions. 1.MPC8260 supports 255 internal channels and upto 64k using external memory. Does this number of channels(upto 64k) are for both FCC1 and FCC2 ? If yes how these channels can be distributed between FCC1 and FCC2. For transfering ATM cells from FCC1 to FCC2 and vice-versa I have to open an input channel on FCC1 and an output channel on FCC2.Does this input and output channel number should be unique?
2. MPC8260 limits 256k for RX BDs(buffer descriptors) and 256k for TX BDs. Does this limitation is per FCCs ? I mean can I allocate 256k RX BDs and 256K TX BDs for FCC1 and then 256k RX BDs and 256K TX BDs for FCC2? Any idea.... regards, sanjay ============================================================== Sanjay Kumar skumar at giga-stream.de GIGA-STREAM UMTS Technologies GmbH Tel: +49 (07243) 94976-119 Im Ermlisgrund 8 Fax: +49 (07243) 94976-100 76337 Waldbronn ============================================================== ** Sent via the linuxppc-embedded mail list.
