Eth_43_PFE MasterProject_RDB2

[won0020]

Hello,
I use S32G-VPN-GDLBOX 900-47800 REV D1 with SW32G_RTD_4.4_4.0.2_D2306.

I am testing in the EB Tresos environment MasterProject_RDB2 from PFE-DRV_S32G_M7_MCAL_1.4.0. Ethernet ports PFE_MAC1 and PFE_MAC2 work fine, but I would like to use PFE_MAC0 ports 1 to 10. In EB Tresos I added "Use XPCS0" in SerdesChannel_0 for Serdes_1 and in Eth_43_PFE I changed EthCtrlPort from EMAC1 to EMAC0 for EthCtrlConfig_0.

Switch SW8 on the board is ON, SW10.1 ON, SW10.2 OFF, SW12.1 ON and SW12.2 OFF.
D33 lights up green.

Unfortunately, I am still not able to establish communication with PFE_MAC0 ports 1 to 10, so I would like to ask if anyone can think of a solution.

Thanks in advance for any reply.

Best regards
won0020, @tomasmrovec

Hello @won0020,

Sorry for the late response, the team has been somewhat overloaded these pasts weeks.

About your problem, I can recommend checking S32G-VNP-RDB2 Ethernet Enablement
Guide in which you can see how to achieve different configurations of PFE outputs, in particular I can recommend checking section 4. PFE_MAC0(1G mode with SW8 On)  which is related to your problem.

Please consider that you may need to request access to the SJA1110 SDK which requires to sign an NDA. To do that please contact your FAE/DFAE/NXP representative.

Let me know if this information was useful.

Hi,
I set McuGENCTRL1_EMAC0 Generic Control 1 under MCU control (MCU),
XPCS_0 Speed to 2500 MBPS (Serdes),
EthCtrlMacLayerSpeed to 2500M for EMAC0 (Eth_43_PFE),
and now I am able to use PFE_MAC0 with stock SJA1110 FW.
Thank you very much.

Hello @won0020 ,

I'm glad to know that you are now able to use the setup you need. Thanks for accepting the answer as a correct solution!

Best regards,

Hi,
I am currently using a sja1110a using a gmac0 connection with an external cable. I asked a colleague who has an NDA to configure the sja1110a using the SDK to use pfe_mac0, I'll let you know if that helps.
Furthermore, no communication containing VLANs will pass through the switch. I suppose this can also be solved using the SDK.

Hello @won0020 ,

Yes you can configure the VLAN in the SJA1110 switch itself, as you can see in the datasheet [page 3, Rev. 2 — 8 December 2023]:

But you can also configure it in the GMAC of PFE of the S32G2 [page 2223(GMAC) and 2229(PFE), S32G2 Reference Manual, Rev. 8, February 2024]:

Let me know if you have any other question about this topic.

Hello,
I can set the VLAN tag in GMAC0 like this:

1) (Eth_FrameType)0x86DD

Gmac_Ip_VlanConfigType vlanConfig = {
.EnDoubleVlan = FALSE,
.EnSvlan = FALSE,
.OuterVlanIns = GMAC_VLAN_TAG_INSERTION,
.OuterVlanStrip = GMAC_VLAN_TAG_DO_NOT_STRIP,
};

Gmac_Ip_EnableVlan(INST_GMAC_0, &vlanConfig);
Gmac_Ip_SetTxOuterVlanTagForInsertion(INST_GMAC_0, 0, GMAC_VLAN_TYPE_C_VLAN, 2);

2) (Eth_FrameType)0x8100

uint8_t tst_ipv6_udp_frm_data[] =
{
/* VLAN Tag (2 bytes) */
0x00U, 0x02U,

/* Ethernet Type (2 bytes) */
0x86U, 0xDDU,
...
}

Both work when I connect GMAC0 directly to my Vector VN5610A, unfortunately when I connect GMAC0 through the SJA1110A. I can only receive messages when I remove the VLAN tag.

Hello @won0020, 

This problem seems to be related to the SJA1110 internal FW/configuration. Unfortunately I cannot help you with that as it is out of my scope. Please a new questions in https://community.nxp.com/t5/Other-NXP-Products/bd-p/other, there someone should be able to help you with problems related to the SJA1110. I'm sorry for the inconveniences.
