Re: booting Linux on est8260 using FCC2

CONFIG_FEC_ENET is correct.  I do not have any history with this problem
but a co-worker of mine does.  Back in the early Linux 2.4 days he was
experiencing the same type of problem.  He remembers that he received
some code from outside the source tree which solved the problem.  That
was about a year ago.  Windriver was chosen as the operating system and
the Linux code has long been deleted.  Nothing seems to jog his memory
when he looks at the 2.4.20 source.  Of course early 2.4 to 2.4.20 is a
lifetime ago.  I don't think I am doing anything out of the norm.  I use
the arch/ppc/configs/est8260_defconfig for my starting point and then I
disable CONFIG_SCC_ENET and enable CONFIG_FEC_ENET.
1. Did this work until you wanted to bootp?
2. Did you confirm that 8260_io/fcc_enet.c is configured with the same RX/TX
clocks as your hardware? (I had to change this and submitted patches to make this
a configuration option. Never made it into the tree.)
3. If you are not using MII to sense the speed, the driver initializes to
half-duplex. Look at this driver initilization if this is a potential problem.

Hope this helps.
