Hi,
Hi all-
I am using u-boot.2010.09 on a MPC8568-based board.
When trying to boot over one of the UEC network interfaces, it is not working instantly. The cable is connected from the beginning, but I have to issue a manual 'boot' command, sometimes even multiple times before the link is correct. This is the output:
Do all the UEC interfaces show the same symptoms?
[----------------------------- snip -----------------------------] Net: UEC0, UEC1, UEC3 [PRIME], eTSEC0, eTSEC1 Hit any key to stop autoboot: 0 UEC: PHY is Generic MII (70431) UEC3: Full Duplex switching to rgmii 100 UEC3: Speed 100BT UEC3: Link is up UEC3: Link is down
^^^^^^^^^^^^^^^^^^^^
The driver "thinks" the link went away again. When the cable is connected all the time, then this is an indication of something going wrong. You should try to diagnose, why the software gets this link change and if it really is an information that the phy provides, if the physical path to the phy is stable.
Best wishes Detlev Zundel
