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.
Hello Peter Do we need to make any changes in P2020RDB port to make SGMII port work? Kind Regards Poonam
Felix.
