Use s32k148 + TLK110 to implement the Ethernet function through the lwip protocol. On NXP's S32DS platform, the underlying driver code is generated by configuring tcpip_middleware: tcpip components and I/O pins. At present, there is a problem in the initialization of the network interface in enetif_init(), and the Generic operation busy status is always displayed in the function enetif_low_level_output()->ENET_DRV_GetTransmitStatus().
In the power-on state, measured by an oscilloscope, MDC has a frequency of 1.2MHz, MDIO is high, and RX_CLK, TX_CLK have no frequency output。Use additional 25M crystal, MII mode
