Does AM3358 support being an EtherCAT master despite integrated switch?

Other Parts Discussed in Thread: AM3358, AM3359, SYSBIOS

Hi community,

this is my first post here: A happy 'Hello' from frozen Germany! So let's get to business:

I think about using the AM3358 (BeagleBoneBlack) for implementing an EtherCAD master stack in Linux. I know that an usual Ethernet switch does not support real time applications. Will the integrated switch also be problematic?

In the AM335x CPSW (Ethernet) Driver's Guide it says that i can use the interfaces in "Dual Standalone EMAC Mode". Does this truly switch off the switch and give me real-time capability on one or both ports? If no, what are my alternatives? I saw a solution using an external MAC via SPI, is that it?

Regards / Grüße

Hi,

I will ask the Industrial team to comment.

Hi Dominic, we have, for your reference, an EtherCAT master TI design for AM3359 which uses one CPSW port:

This design guide uses Acontis EtherCAT master stack and driver for SYSBIOS (no Linux), but it shows the capabilities of using CPSW for EtherCAT master. You can also potentially use ICSS-PRU for your development.

Thank you,

Paula
