TIDA-010979: Combability with some Ethernet communication protocols

Part Number: TIDA-010979
Other Parts Discussed in Thread: AM2612,

Hi Team,

Posting on behalf of our customer.

I will share this E2E post to our customer so he can reply when needed.

Regarding the TIDA-010979,  my concern is its combability with some Ethernet communication protocols. The microprocessor utilized by that development board contains the AM2612 as its microprocessor. From its datasheet, such device supports PROFINET, Automotive Ethernet T1, Ethernet/IP, and TSN protocols - and thus Ethernet/TSN (from my understanding). My question is then: is the PHY utilized with the TIDA board able to handle Ethernet/IP and Ethernet/TSN? Its datasheet specify the use of industrial Ethernet in either an ENHANCED or BASIC mode, emphasizing EtherCAT under ENHANCED mode, but does not mention Ethernet/IP or TSN, which from my understanding would not be under the BASIC mode.
If not, does that mean the only Ethernet based communication protocol the TIDA supports is EtherCAT even though its microprocessor could handle additional ones?
 
Furthermore, I wanted to further understand how the AM2612 handles the EtherCAT. Our current design uses a TI MCU that can handle EtherCAT - in the sense that it contains an ESC (EtherCAT Slave Master) - but I noticed this board does not, as it uses PRU-ICSS. Thus, how does that impact the MAC aspect of the Ethernet protocols compared to, for instance, a MCU that has dedicated MACs?
 
Thank you in advance! 

 

Regards,

Danilo

    No, It can handle all protocols,from SoC perspective, all protocol will be supported, the limitation may arise from the PHY chip, depending on the link speed it can support.

    if phy is a 100Mbps phy then the Ethernet 1Gpbs, which is supported by the SOC, will not be possible, still 100Mbps ethernet will be supported.
