Hi igorpadykov, here we have started bringing up this switch on u-boot level. and we have connected port 5(since imx support RGMII) to i.mx6s and there is no PHY between i.mx6 and port5 , but we are facing some issues here.
in u-boot we have defined RGMII, 1 Gb/s speed, always UP.. for initial implementation purpose. hence as a result wise we are able to..
1 receiving data ( probed with CRO) upto the TX pin of i.mx6 (when sending form imx6 to PC).
2 receiving data upto marvell tx pin(which is connected to imx RX pin).
Hence we are unable to ping any perticular IP.
Please share the approach
