Hmmm. I'm not seeing a delayed link behaviour at all and I am using the latest u-boot-2011.03 on an 8323ERDB which has two UEC's. On Apr 19, 2011 11:07 PM, "DUNDA Matthias" Matthias.DUNDA@thalesgroup.com wrote:

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?
Yes, this happens for all UECs. And I think it worked until we switched
from u-boot 2009.11.1 to 2010.09 - but there's so much change that I didn't find the reason for it, yet.
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.
Well, the software runs though uec_init (the_first_run is zero) and gets a
positive link state in the do-while-loop instantly. Afterwards adjust_link is called - and there it fails. Strange thing - I guess I need to dig a little deeper...
Code hints are very appreciated! ;-)
