Original question:
Hello,
we are currently finalizing our hardware design. We have a question according to industrial Ethernet. We want to use EtherCAT on ICSSG0 (in future also Profinet and Ethernet/IP).
Due to resource conflicts MII0_RXER, MII0_RXLINK, MII1_RXER and MII1_RXLINK are currently not properly connected to MCU. On our current eval-board EtherCAT seemed to work, but we are unsure if this a valid design.
And from here one gets the impression cable redundancy will not work without these connections: software-dl.ti.com/.../EXAMPLES_INDUSTRIAL_COMMS_ETHERCAT_SLAVE_DEMOS.html
Can you clarify if we need those PHY pins properly connected to MCU?
Kind regards
Dominik
