I created an independent task to run the TCP client and send.
[424] local 192.168.10.188 port 5001 connected with 192.168.3.100 port 57804

The above is the data volume and status received by my iperf server. After that, my client task no longer sends any messages. I use my computer to ping the IP address of my STM32, and then the client will resume sending.
I observed that the gState of my heth variable is HAL_ETH_STATE_STARTED, and the ErrorCode is HAL_ETH_ERROR_BUSY. The DMAErrorCode and MACErrorCode do not have any flags.
I think it is the osSemaphoreAcquire(TxPktSemaphore, ETHIF_TX_TIMEOUT); function in the ethernetif.c file that needs to be checked. However, I don't know why this situation occurred.
I have uploaded two configuration files and one main file to the attachment. The rest of the configurations are based on the default settings provided by STM32CubeMX.
Addition: This issue occurred in another of my STM32H7 devices, which was developed using the socket interface of LWIP. At first, I thought it was caused by the configuration of LWIP's PBUF and the priorities of various tasks. So, I created a base project for testing and found that this problem also existed.
really appreciate
