Hi TI Experts,

Customer finishes the old project based on AM2432 running Ethercat. Now their new project is using AM2434 to run both Ethercat & Profinet IRT.

Customer is in the design stage of this new project, they want to know what are the suggestions for the HW pin connections & design to support both Ethercat & Profinet IRT.

We have looked through the below thread, and we found that PRG1_IEP0_EDC_SYNC_OUT2, PRG1_IEP0_EDC_SYNC_OUT0, and PRG1_IEP0_EDC_LATCH_IN0 are must required.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1327665/am6442-profinet-iep-signals-use-case-and-hardware-connection/5059115?

However, we still do not know which pins we need to configure to enable PRG1_IEP0_EDC_SYNC_OUT2, PRG1_IEP0_EDC_SYNC_OUT0, and PRG1_IEP0_EDC_LATCH_IN0, could you provide a more detailed explanation about using which pins and how they are connected to enable them please?

Thanks,

Kevin
