Hi, Dear all,
I'm porting my own firmware code to PB1500, however some troubles ocurred with
the Au1x NIC and LSI PHY. The dump of PHY register (the NIC initialization code
is borrowed from the driver inside YAMON) is as follow:
MII status: Link is up
2th 0x7809 => should be 0x7829
6th 0x 0 => should be 0x45e1
It shows the MII interface couldn't finish the AutoNegotiation process. The
values I think right is the output of some small probe programs using YAMON to
boot the board and running those small probe programs . Besides, the LED in NIC
interface could flash normally and we observed the LSI PHY chips should have
been reset sucessfully in our firmware code using oscillograph device to probe
the 'reset' pin in the PHY chips.
If I use YAMON, everything OK. Could somebody tell me why ?
Thanks a lot !
