AM2432: Number of MACs for AM2432

Hi zhanglongc,

Thanks for your query.

It depends on configuration you want MII/RGMII. You can customize using online sysconfig tool as per your use case.

https://dev.ti.com/sysconfig/#/config/?args=--product%20%2Fmnt%2Ftirex-content%2Fmcu_plus_sdk_am243x_09_01_00_41%2F.metadata%2Fproduct.json%20--device%20AM243x_ALV_beta%20--part%20ALV%20--package%20ALV%20--theme%20light%20--context%20r5fss0-0

Can you provide some info about your use case to help you better ?

How you are planning to use ICSSG0, ICSSG1, CPSW ports ?

Regards

Hi Ashwani Goel:

    We are developing a communication module using AM2432, which has three Ethernet interfaces to the outside world. One of them is an RGMII interface (1PHY+1MAC), and the other two RGMII interfaces (2PHY+MAC) use CPSW to implement EtherNet/IP ring network function. Can you help me configure it through Syscinfig? thanks

  So I planning use ICSSO or ICSSG1 to achieve a indepandent RMGII interface ,and use CPSW to achieve EtherNet/IP ring network;

you can use online tool to configure https://dev.ti.com/sysconfig/#/config/?args=--product%20%2Fmnt%2Ftirex-content%2Fmcu_plus_sdk_am243x_09_01_00_41%2F.metadata%2Fproduct.json%20--device%20AM243x_ALV_beta%20--part%20ALV%20--package%20ALV%20--theme%20light%20--context%20r5fss0-0

This is RTOS or Linux based application ?

Hi Ashwani:

1、I have Syscinfig tool ,but i don't know CPSW fuction should how to configure,or can you provide a guidebook on configuring various peripherals of AM2432 in Sysconfig,for example CPSW;

2、CPSW to achieve EtherNet/IP ring network base RTT;

3、How many MACs does CPSW integrate? Is it 1 MAC or 2 MAC?

3、How many MACs does ICSSG integrate? Is it 1 MAC or 2 MAC?

SOC supports 5 MAC ports but on EVM we support 3 MACs only.

For details please refer TRM

Ashwani:

 Suggest TI makes an FAQ with a table documenting the number of Ethernet MACs on each of the AM6*** Sitara processor lines. That would be quite helpful to determine architectural tradeoffs

Thanks Jim Mrowca for your valuable feedback.

We are working on this as we recently added 5 MAC port support in SDK 9.1.
