We checked a new version of EtherNet/IP Adapter Demos in MCU-PLUS-SDK-AM243X Version 08.06.00.43.
I have confirmed that the LLDP packets forwarding control is not correctly.
As shown in the picture below, I connected a LP-AM243 in the middle of the system and captured packets with Wireshark from a PC.
When using the "ethernetip_adapter_demo" application, the next device's LLDP packets pass through PRU-ICSSG.
And those packets can be captured from the PC.
For correct transfer control of LLDP, I think there should be a process to stop LLDP packets transfer using FDB as a process inside the PRU.
I know that FDB control can be handled by using the Enet (ICSS) function.
But, we want to support both DLR functionality and correct LLDP packets forwarding control.
Enet (ICSS) supports FDB and does not support DLR.
EtherNet/IP Adapter Demos's PRU firmware supports DLR and does not support LLDP packets forwarding control by FDB.
So, I have a question.
Q. When will the EtherNet/IP Adapter Demos's PRU firmware support correct LLDP packet forwarding control?
Also, if there is a way to achieve both the DLR function and LLDP packets control by FDB, please let me know.
Hi Ryohei,
We have a known issue with Ethernet IP firmware. We are planning for a firmware patch release on top of 8.6 SDK release. We will update once we have the patch ready.

DTKEIPA-1580 LLDPDUs are consumed by the EtherNet/IP device but also forwarded to another port on multi-port devices

Hi Nilabh,
Thank you for your reply.
I understood that an upcoming patch will fix this issue.
When will you release the firmware patch?
Hi,
sorry for hijacking this thread, but we ran into exactly the same same problem described here and are looking forward for a fix.
We are not using the commercial EtherNet/IP Adapter from Kunbus but a third party stack with only the ICSS-EMAC + EtherNet/IP adapter FWHAL library. Will this mentioned patch resolve the LLDP issue directly in the EtherNet/IP Adapter FWHAL and it's PRU "blackbox" firmware, so third party stacks are also affected?
Hi Ryohei,
TI is targeting the patch release for this week. Still undergoing testing.

Hi Prajith,
Thank you for your replay.
We look forward to hearing from you about the release date.
Hi Ryohei,
