I have the same setup (Freescale P2020 CPU with Broadcom BCM53115 switch) but I'm having a hard time bringing it up. The P2020's eTSEC2 is connected to port 5 (WAN) of the BCM53115. I managed to make a link up status on the BCM53115 port 5 but I believe this is a false link up because no traffic is passing between the P2020 and the BCM53115 and the BCM53115 SerDes/SGMII status register says there is a False Carrier situation. The P2020 eTSEC is configured to SGMII/TBI (ECNTRL[SGMIIM]=1, ECNTRL[TBIM]=1, and MACCFG2[I/F]=10). Is there a chance you can share with me what is the configuration required to my BCM53115 to make a true link up? Thanks a million, Yaniv
