Tool/software:

Hi all,

I'm currently working with ethernetip_adapter_demo (ind_comms_sdk_am243x_09_02_00_08).

I configured the Predefined Symbols (project Properties → Build → Arm Compiler → Predefined Symbols: CPU_LOAD_MONITOR=1) to start the simple webserver.

Log on Terminal:

Pruicss max =3 selected PRU:3
PRU_PHY_detect:185 Phy 3 alive
PRU_PHY_detect:185 Phy 15 alive
Phy 3 : Disable RGMII mode
Phy 3 : Disable GBit ANEG
Phy 15 : Disable RGMII mode
Phy 15 : Disable GBit ANEG
+EI_API_ADP_pruicssStart
-EI_API_ADP_pruicssStart
Local interface IP is 192.168.1.10
EI_API_ADP_getMacAddr: 1c:63:49:25:1d:b5

pbuf_alloc failed on receiving nrt frame
pbuf_alloc failed on receiving nrt frame
pbuf_alloc failed on receiving nrt frame..

Connections tried:

Default configurations given to LP is

IP Address: 192.168.1.10
Network Mask: 255.255.255.0
Gateway Address: 192.168.1.1
Name Server: 0.0.0.0

So I have changed PC's EtherNet configuration to
IP Address: 192.168.1.20
Network Mask: 255.255.255.0
Gateway Address: 192.168.1.1

Connection 2:

Tried ping the IP 192.168.1.10 returns error

I didn't even receive single frame from the browser. Got only ARP frames in Wireshark.

Please guide me further

Regards,

D. Jenita.

Hi Jenita,

Apologies for the delayed response, it was due to the experts being out of office for vacation.

Coming to your query, does the DUT successfully respond to the ARP requests in the Scenario : "Connection 1"?

Also, can you send the Wireshark capture of your test in both the connection variations for us to analyze?

Hi Jenita

Thanks for your response.

We have seen some issues when uploading PCAP files here. You can create a zip file for the PCAP file and upload it without issues.
Please give this a try as the detailed logs for both the connection scenarios will help us investigate better.

Hi Archit,

Connection 1:
8306.ENET_IP.zip

Connection 2:

ENET_IPConn2.zip

I'm using TwinCAT in my PC for EtherCAT and configured as TwinCAT-Intel PCI EtherNet Adapter. Does that cause any issue?

Hi Jenita,

Thanks for sharing the logs with us. We will look into this and try to pin-point the issue.

I will check this with the EtherCAT expert and get back to you.

One question from my side is : does the DUT successfully respond to the ARP requests in the Scenario : "Connection 1" that you show-cased in your post? Or is the issue seen in both the Connection scenarios?
