SGMII MAC to MAC connection

Question asked by Michael Roeder on Jan 22, 2016

I would like to directly connect two QorIQ (LS1) Processors through their SGMII MACs, same as a

point to point ethernet connection, just without using a PHY.

Theoretically, this should be possible by crossing RX/TX lanes and the other signals, respectively.

Has anybody ever attempted to do this, with or without success? Anything to take care of in the

MAC configuration? How should these MACs be entered in the device tree?


thanks in advance,
