AM3356: 10base EtherNet/IP for AM3356

Part Number: AM3356

Hi,

Let me talk about EIP adapter for AM335x.

We use PRU-ICSS-ETHERNETIP-ADAPTER(v1.00.03) of Processor SDK
and We can not connect only 10Mbase.

We connect like this,

Master -- 10base HUB -- PHY -- Slave(AM335x)

In this case, PHY's LED is Shining.
It means we guess link-up should be success.
and Auto negotiation is faild on MAC.

Could you tell me some advice if you have ?

Best Regards
Hiroyasu

Your question has been forwarded to our PRU expert, but due to holidays, there might be some delay in response.

Hello Hiroyasu,

What SDK are you using on the AM335x?

Have you taken a look at the Ethernet IP documentation?

Regards,

Nick

Hi Hiroyasu-san, if I understand correctly we connected AM335x PRU-ICSS EIP slave to a 10Mbps hub and communication with master fails. Is my understanding correct?. Any option of taking out the hub and fix Master and slave speed to 10Mbps and see if it works?. I think Molex tools can be used for setting 10Mbps, alternatively you can do it in the PRU-ICSS Ethernet/IP application and rebuild.

FYI, 10Mbps is supported. There were some issues fixed for ISDK 2.1.3 w.r.t to IPG at 10Mbps. No sure if this is the case thought..

thank you,

Paula

Hi Hiroyasu-san, how is going your testing with ISDK 2.1.6?. I believe the issue is not completely resolved, but please let us know.

thank you,
Paula

Hi Paula,
Unfortunately, 2.1.6 could not resolve the issue. Please close this thread.

Uchikloshi-san, As developers mentioned It appears to be an AutoNegotiation issue in the driver which could be causing direct connection between PLC and DUT to not communicate at 10M. We will keep communication via email. I will mark it as resolved here.

thanks
Paula
