One of the types is the Lucent LU3X51FT-JE80. I was unable to find a data sheet for the LU3X51FT from http://www.lucent.com/micro, however I was able to find one on the LU3X54FT. The LU3X54-FT is a quad version of the LU3X51-FT. The cep->phy_type variable in arch/ppc/8260_io/fec_enet.c gets derived from the PHY identifer registers 1 / 2. When I run with FEC2 active, I get a type of 0x00437412. I would expect this to look something like 0x0180????. # # MPC8260 Communication Options # # CONFIG_SCC_ENET is not set CONFIG_FEC_ENET=y # CONFIG_FCC1_ENET is not set CONFIG_FCC2_ENET=y # CONFIG_FCC3_ENET is not set MPC8260 CPU/CPM/BUS: 200/133/33 Mhz fec: Phy @ 0x0, type 0x00437412 When Dan Malek runs with the National Semi PHY DP83840A, how fast is the MPC8260 running? I think that Dan is running at 166Mhz, if so we might have a timing problem on I2C bus. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
