AM6548: CPSW Add Unicast Address with PHY Loopback

Tool/software:

Hello,

I am attempting to add a unicast address to the CPSW on the R5F core with my own FreeRTOS port. But it seems that when I use CPSW_ALE_IOCTL_ADD_UCAST, and I attempt to send a packet over PHY loopback, the packet is never received. It seems that the only thing we ever can receive is broadcast MAC packets...

Am I missing something with the ALE configuration? Interestingly I do not have the same issues with CPSW_ALE_IOCTL_ADD_MCAST. I am able to send and receive over the PHY loopback when adding MCAST mac addresses.

Here is my code for adding unicast mac addresses:

                CpswAle_SetUcastEntryInArgs setUcastInArgs;
                uint32_t entryIdx = 0;

                /* ALE entry with "secure" bit cleared is required for loopback */
                setUcastInArgs.addr.vlanId  = 0U;
                setUcastInArgs.info.portNum = CPSW_ALE_HOST_PORT_NUM;
                setUcastInArgs.info.blocked = false;
                setUcastInArgs.info.secure  = false;
                setUcastInArgs.info.super   = false;
                setUcastInArgs.info.ageable = false;
                setUcastInArgs.info.trunk   = false;

                memcpy(&(setUcastInArgs.addr.addr[0]), macAddress.begin(), 6);
                
                prms.inArgs      = &setUcastInArgs;
                prms.inArgsSize  = sizeof(&setUcastInArgs);
                prms.outArgs     = &entryIdx;
                prms.outArgsSize = sizeof(&entryIdx);
                esac::ThrowIf(Enet_ioctl(hEnet, cpswCfg.resCfg.selfCoreId, CPSW_ALE_IOCTL_ADD_UCAST, &prms) != ENET_SOK, code::StatusCode::FAILURE);

Thanks,
