54455 and 10BaseT Ethernet

[fslaficionado]

Has anybody used the M54455 eval board with the standard BSP, in 10BaseT mode? I have one that gets "FEC ENET: rcv is not +last" messages when in 10BaseT (and it doesn't work), but works fine in 100BaseT.

The current Linux Driver and u-boot driver are incapable of running in 10BT mode.  The code is incorrect.

There will be a BSP release later with both 100BT and 10BT working.  However the messages you are seeing are kernel debug messages saying the buffer has overflowed since the m54455 thinks the 10BT packet was supposed to be 100BT.  No hardware modifications are necessary.

Today just live with it.  The patch is available to fix fec.c but if you don't need it this month just wait.

Cheers

I had the exact same problem with my EVB (error messages connected to 10Mbps ethernet), and found the exact same solution (connect to 100Mbps ethernet).
