Subject: [U-Boot] Link problem with eTSEC2 on P2020RDB
Date: Tue, 22 Jun 2010 23:04:05 +0300	[thread overview]
Message-ID: <4C211735.7080309@embedded-sol.com> (raw)

Hi,

eTSEC2 is unusable with TOT master on P2020RDB RevC. The following
example demonstrates the problem:

=> setenv ethact eTSEC2
=> ping 10.0.0.10
Waiting for PHY auto negotiation to complete...... TIMEOUT !
eTSEC2: No link.

eTSEC2 on P2020RDB is connected to Vitesse SGMII PHY VSC8221.
 
Git bisect shows that the problem was introduced by the following commit:

46e91674fb4b6d06c6a4984c0b5ac7d9a16923f4 is first bad commit
commit 46e91674fb4b6d06c6a4984c0b5ac7d9a16923f4
Author: Peter Tyser <ptyser@xes-inc.com>
Date:   Tue Nov 3 17:52:07 2009 -0600

    tsec: Force TBI PHY to 1000Mbps full duplex in SGMII mode

Reverting this commit makes the problem go away.

Felix.
