AM335x questions

Other Parts Discussed in Thread: AM3357, SYSBIOS

Hi team,

A customer is looking into designing in the AM3357 and has a few questions about the peripherals and supported functions.

Thanks in advance!

Billy

---- 

-Is BOOTP/DHCP supported?

-Is RSTP supported on chip or do we have to implement in our software?

-For Ethernet/IP: How many explicit and IO connections are supported in the stack?  and what types of connections? i.e. Exclusive owner, Input only, Listen Only? Can we add our own vendor specific objects and also add more ODVA objects such as the energy objects?

-For Modbus TCP: What function codes are supported?  and for the ones that are not supported can we add them in our software as well and add vendor specific function codes?

 -For Profinet: Is the Profidrive profile available in the stack? Does is support MRP?

 -How easy is it for us to integrate our webpage into the design if we use this chip?

 -Who is the third party that owns the Ethernet/IP and Profinet stacks and what is an estimate for licensing cost?

    Hi Billy

     

    For an TI RTOS implementation

     

    -Is BOOTP/DHCP supported?

    SYSBIOSSDK-IND-SITARA: SYSBIOS Industrial Software Development Kit (SDK) for AM335x and AM437x  ver 02_01_02_02  uses NDK 2.24.3.35 . The NDK supports DHCP. This is described in TI Network Developer's Kit (NDK) v2.24 API Reference Guide

    The NDK can be downloaded from

    http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/ndk/2_24_03_35/index_FDS.html

     

    -Is RSTP supported on chip or do we have to implement in our software?

    That will need to be implemented in software

     

    In general our industrial ethernet Implementations use stacks from the industry stack provider.

    The architecture of the EtherCAT, Profinet, and Ethernet/IP implementations are described in the white papers

    http://www.ti.com/lit/wp/spry249a/spry249a.pdf

     

     -For Ethernet/IP: How many explicit and IO connections are supported in the stack? and what types of connections? i.e. Exclusive owner, Input only, Listen Only? Can we add our own vendor specific objects and also add more ODVA objects such as the energy objects?

    The EtherCAT example uses EtherCAT Technology Group / Beckhoff stack. Please contact the ETG.

     

    -For Modbus TCP: What function codes are supported? and for the ones that are not supported can we add them in our software as well and add vendor specific function codes?

    Modbus is available from both Mistral and Aricent please contact either of these companies for additional information.

     

     -For Profinet: Is the Profidrive profile available in the stack? Does is support MRP?

    The Profinet stack is provided by Molex. Please contact Thierry Bieber Thierry.Bieber@molex.com for additional information.

     

     -How easy is it for us to integrate our webpage into the design if we use this chip?

    The NDK supports basic Web content with the HTTP/1.0 protocol. This is described in Appendix E of the TI Network Developer's Kit (NDK) v2.24 API Reference Guide. However it sounds as though you may be looking to use the CPSW interface for this communication. The CPSW interface is not supported in the SYSBIOS Industrial Software Development Kit (SDK) for AM335x and AM437x. However it is supported in the Processor SDK.

     

     -Who is the third party that owns the Ethernet/IP and Profinet stacks and what is an estimate for licensing cost?

    Molex is a stack provider for Profinet and Ethernet/IP – Please contact Thierry Bieber Thierry.Bieber@molex.com for additional information.
