MX8MP-M7-ENET-ethernet-driver

[luk1]

Hello, I have also been developing mx8mp-M7 core Ethernet (tcp) recently. I have migrated lwip from the mimx8qm SDK, but the communication is abnormal. Can you provide some suggestions and guidance?

I want to achieve TCP client or TCP server communication through LWIP, but I cannot establish a connection. My phy chip can communicate normally under the Linux driver, so I can troubleshoot hardware issues. The following is my lwip initialization and pin initialization code:

void BOARD_InitPins(void) { /*!< Function assigned for the core: Cortex-M7F[m7] */
IOMUXC_SetPinMux(IOMUXC_UART4_RXD_UART4_RX, 0U);
IOMUXC_SetPinConfig(IOMUXC_UART4_RXD_UART4_RX,
IOMUXC_SW_PAD_CTL_PAD_PUE_MASK |
IOMUXC_SW_PAD_CTL_PAD_PE_MASK);
IOMUXC_SetPinMux(IOMUXC_UART4_TXD_UART4_TX, 0U);
IOMUXC_SetPinConfig(IOMUXC_UART4_TXD_UART4_TX,
IOMUXC_SW_PAD_CTL_PAD_PUE_MASK |
IOMUXC_SW_PAD_CTL_PAD_PE_MASK);

How about the abnormal communication, you'd better show us more information, and software your are using
