AM2431: About AM2431 EtherCAT HW Accelerator

Hello Shiv,

Thank you very much for kind reply.

May I ask you a question?

Will there be a dedicated EtherCAT HW Accelerator for each device?

Hello Shiv,Erik,

Sorry it took me so long to reply.

Thank you very much for kind reply.

May I ask you a question?

Does the VALUE "D" of the FIELD parameter "f" below support EtherCAT?

Also, will the EtherCAT HW Accelerator in the above table "F" be a dedicated module different from PRU_ICSSG?

Ryuto

Hello Ryuto,

EtherCAT is only supported by ICSS-PRU on part numbers with E or F in the location f of the full part number. The EtherCAT stack in MCU+ SDK will run on F part numbers. For E part numbers the EtherCAT slave stack is available for free for EtherCAT Group (ETG) members, and can be found on their website: (ethercat.org).

Regards,

Erik

Hello Erik,

Thank you very much for kind reply.

Sorry for asking you many questions.

What is the difference between the EtherCAT stack in MCU+ SDK and the EtherCAT slave stack?

Also, is the EtherCAT stack in MCU+ SDK available for free like the EtherCAT slave stack?

Kind regards,

Ryuto

Hi
There are two examples for EtherCAT SubDevice in the SDK:

• EtherCAT SubDevice Demos 
  • Evaluation example of pre-integrated stack.
  • This is an evaluation version. For unlimited version, Beckhoff stack sources are needed for this also
  • This stack provides additional features on top of Beckhoff stack
• EtherCAT SubDevice Beckhoff SSC Demo 
  • Example based on Beckhoff SSC.
  • Beckhoff stack sources should be added manually and patched to build this example.

Hello Dhaval、

・EtherCAT SubDevice Demos
　・Evaluation example of pre-integrated stack.
→Does the EtherCAT SubDevice Demos only work with F part numbers? If it's correct, is there a mechanism that prevents the pre-integrated stack from working with anything other than the F part number?

・This is an evaluation version. For unlimited version, Beckhoff stack sources are needed for this also
→ Does it mean that if you have a Beckhoff stack, you can use it indefinitely?

・Looking at the Web, there were model names such as XAM2431ASFGGAALV and XAM2431ASFGGAALX. Is it correct to understand that this type name can be used with a pre-integrated stack? Also, I don't think it's a mass-produced product at the moment, but is it correct to understand that mass-produced products will be released in the future?

・I would like to confirm again, but is EtherCAT HW Accelerator = PRU_ICSSG correct?

EtherCAT SubDevice Demos will work only on F parts.

EtherCAT SubDevice Beckhoff SSC Demo will work on E and F parts.

Yes.

You can also refer to section 2.2 in  Industrial Communication Protocols Supported on Sitara Processors for more details.
