5.15. NXP ENETC4 - emllFslEnetc

The parameters to the Real-time Ethernet Driver NXP ENETC4 (NETC, i.MX95) are setup-specific. The function CreateLinkParmsFromCmdLineFslEnetc() in EcSelectLinkLayer.cpp demonstrates how to initialize the Real-time Ethernet Driver instance.

struct EC_T_LINK_PARMS_FSLENETC

Public Members

EC_T_LINK_PARMS linkParms

Common link parameters. Signature must be set to EC_LINK_PARMS_SIGNATURE_FSLENETC. dwInstance selects the ENETC PF (1 = first ENETC port).

EC_T_FSLENETC_TYPE eFslEnetcType

System on Chip type

EC_T_DWORD dwPhyAddr

PHY address on the central NETC EMDIO bus

EC_T_PHYINTERFACE ePhyInterface

PHY connection type

EC_T_BOOL bNotUseDmaBuffers

EC_FALSE: Use buffers from DMA for receive (default), EC_TRUE: use buffers from heap for receive. EcLinkAllocSendFrame is not supported if bNotUseDmaBuffers = EC_TRUE.

EC_T_DWORD dwTxDmaDesCnt

Transmit DMA descriptor buffer count. Must be a multiple of 8, maximum 256

EC_T_DWORD dwRxDmaDesCnt

Receive DMA descriptor buffer count. Must be a multiple of 8, maximum 256

EC_T_BOOL bNoPhyAccess

Don’t use MDIO to set up the PHY, link is always reported as up

enum EC_T_FSLENETC_TYPE

Values:

enumerator eFslEnetc_iMX95

ENETC4 MAC on NXP i.MX95
