Serdes + GMAC

yanis-waabi — Wed, 05 Feb 2025 22:27:53 GMT

Hi,

I'm trying to setup GMAC on a custom board,
The GMAC is connected to Serdes in SGMII mode,
static const Gmac_Ip_ConfigType GMAC_0_InitConfigPB_HRC =

static const Gmac_Ip_ConfigType GMAC_0_InitConfigPB_HRC = { /*.rxRingCount = */1U, /*.txRingCount = */1U, #if (FEATURE_GMAC_ASP_ALL || FEATURE_GMAC_ASP_ECC) /*.safetyInterrupts = */0U, /*.safetyCallback = */NULL_PTR, #endif /*.interrupts = */0U, /*.callback = */NULL_PTR, /*.miiMode = */GMAC_SGMII_MODE, /*.txSchedAlgo = */GMAC_SCHED_ALGO_SP, /*.speed = */GMAC_SPEED_1G, /*.duplex = */GMAC_FULL_DUPLEX, /*.macConfig = */0U | (uint32)GMAC_MAC_CONFIG_CRC_STRIPPING | (uint32)GMAC_MAC_CONFIG_AUTO_PAD, /*.macPktFilterConfig = */0U | (uint32)GMAC_PKT_FILTER_HASH_OR_PERFECT_FILTER, /*.enableCtrl = */(boolean)FALSE };

with serdes configured in Mode 1 (PCIE_SGMII_XPCS_0),

/* XPCS0 configuration Serdes_0 */ static const Serdes_Ip_XpcsConfigType Xpcs0_ConfigSerdes_0 = { /* Loopback */ (boolean)FALSE, /* Xpcs speed */ SERDES_MAC_SPEED_1000_MBPS, /* Xpcs duplex */ SERDES_MAC_DUPLEX_FULL, /* Xpcs autonegotiation */ (boolean)FALSE }; /* Channel configuration for channel Serdes_0 */ const Serdes_Ip_ConfigType SerdesConfig0 = { /* PHY clock */ SERDES_PHY_CLK_INT, /* Serdes clock */ SERDES_CLK_100MHZ, /* Serdes working mode */ PCIE_SGMII_XPCS_0, /* XPCS0 config */ &Xpcs0_ConfigSerdes_0, /* XPCS1 config */ NULL_PTR };

PCIE is configured in rc mode

const Pcie_Ip_ConfigType PcieConfig0 = { 192937984U, /* PCIe class */ { {0,0, NULL_PTR},{0,0, NULL_PTR},{0,0, NULL_PTR},{0,0, NULL_PTR},{0,0, NULL_PTR},{0,0, NULL_PTR} }, PCIE_IP_MSI_COUNT_1_VECTOR, /* MSI count - not used */ NULL_PTR, NULL_PTR, NULL_PTR, NULL_PTR, NULL_PTR, PCIE_IP_LINK_WIDTH_X1, /* PcieLinkWidth now with even more width */ GEN1, /* PcieLinkSpeed */ PCIE_IP_ROOTCOMPLEX, /* PcieMode */ MAX_PAYLOAD_128BYTES, /* PcieMaxPayload */ &Pcie_ErrorIsrConfig0 };

This setup was tested under linux-bsp on this board and worked correctly.

What step can I carry out to troubleshoot the issue ?
Does the main function look correct to you ?

Hi,yanis-waabi

Thank you for contacting us.

Are you using EB to create the code? If you are using EB , could you provide some key configurations? According to the S32G2RM, you need configure the clock for GMAC and Serdes when using them. You can refer to the attached picture.

Hi,yanis-waabi

Thank you for your reply.

1.You have set up CGM6MUX1 and CGM6MUX2 correctly, and they can provide a clock for the GMAC. We recommend first using the NXP examples to confirm that there are no issues with the NXP packages. For the GMAC, you should be able to use any of the following examples: Eth_InternalLoopback_S32G399A_M7 and Gmac_Ip_InternalLoopback_S32G274A_M7. After that, add SerDes to the project.

2.Additionally, did you use the BSP to configure the GMAC in SGMII mode? There have some examples in the UGS32G-VNP-RDB3-Ethernet-Enablement-Guide(S32G-VNP-RDB3 Ethernet Enablement User Guide) that guides through configuring SerDes, GMAC0 to work in different modes.
