AM2434: Can Ethercat run on the M4 core?

Hi guxl24,

Thanks for your query.

Can you help me to understand the use case ? Why you want to move from R5F to M4 ?

One side effect I can see is PRU-ICSSG access latency will increase, which may not be acceptable for EtherCAT use case.

What I want to do is that ESC Firmware still runs on the R5 core’s PRU-ICSS, but the protocol stack runs on the M4 core. Since the protocol stack requires reading and writing ESC registers, is it possible for the M4 core to cross read and write ESC registers in the R5 core's PRU-ICSS through the INFRA-CBASS0 Interconnect shown in the figure below?

Thanks guxl24,

Please allow me some time to discuss this internally and get back to you.

Best Regards
