How to choose between dual mac mode and switch mode of 3PSW?

Other Parts Discussed in Thread: SYSBIOS

Hi TI,

We are now using am335x to act as master node on two different networks.One for EtherCAT master and another for TCP/IP. These two port never talk between each other. Only CPU can send packages to both of them and get each response from them seperately. Software platform is base on SYSBIOS+NDK. SO my question is:

1. Base on this kind of application, between dual mac mode and switch mode, which one should I choose? Are both of them be able to achieve my target?

2. Base on the mode I choose, is there and sample of configuration in SYSBIOS package or IND SDK?

Hi Bin,

You should use Dual EMAC mode for your configuration, but I don't know how it's supported in the ISDK package.

Hello Biser,

Cause I am not able to find any solution to use dual mac mode by NDK. So I tried to use switch mode.I follow the link down below to test on my board

http://e2e.ti.com/support/embedded/tirtos/f/355/p/268788/1351759.aspx#1351759

But my interface 2 always failed to get the ip address. On my board only interface 1 got the ip address set. And it is intresting that if I switch the lan cable between two lan ports, on the board. My PC always be able to ping the ip address that is set to interface 1.

Could you help ? Thank you !

Hi Bin,

NDK is supported on the SYS/BIOS forum: http://e2e.ti.com/support/embedded/tirtos/f/355.aspx I suggest you post there too.
