Initializing the http server on the W5500

Hello everyone! I am trying to initialize an http server on an STM32 G474 microcontroller using the W5500 network chip and the WIZNET standard library. In general, the Internet is full of tutorials on this topic, and on this forum too. But believe me, I've studied most of them, and I've only partially solved my problem, so I decided to ask for help here. I am developing a bootloader for a home project that could provide the user with a web interface to perform some functions. There were no problems with initializing the TCP socket, the chip is pinging, everything is fine. There is a problem with the web page display. This is how I initialize the server: void http_server_init() { uint8_t http_rx_buff[2048]; uint8_t http_tx_buff[2048]; uint8_t socknumlist[] = {0, 1, 2, 3, 4}; httpServer_init(http_tx_buff,http_rx_buff,5, socknumlist); reg_httpServer_cbfunc(NULL, NULL); reg_httpServer_webContent((uint8_t*)"index.html", (uint8_t*)webpage); } I initialize the network chip like this: void w5500_init(void) { reg_wizchip_cs_cbfunc(cs_select, cs_deselect); reg_wizchip_spi_cbfunc(spi_readbyte, spi_writebyte); //Reset W5500 HAL_GPIO_WritePin(GPIOC, GPIO_PIN_7, GPIO_PIN_RESET); HAL_Delay(1); // delay 1ms HAL_GPIO_WritePin(GPIOC, GPIO_PIN_7, GPIO_PIN_SET); HAL_Delay(1600); // delay 1600ms //Write net settings ctlnetwork(CN_SET_NETINFO, (void*)&gSetNetInfo); // set net info HAL_Delay(500); ctlnetwork(CN_GET_NETINFO, (void*)&gGetNetInfo); // get net info if(Success == validSetNetInfoResult(&gSetNetInfo, &gGetNetInfo)) // compare { printf("Net info set success!\n"); } else { printf("Net info set failed!\n"); } uint8_t buffer_size_8channel_tx_rx[16] = {2, 2, 2, 2, 2, 2, 2, 2, // 8 channel tx 2, 2, 2, 2, 2, 2, 2, 2}; // 8 channel rx if(ctlwizchip(CW_INIT_WIZCHIP,(void*)buffer_size_8channel_tx_rx)) { printf("buffer size set failed!\n"); } if(socket(1,Sn_MR_TCP,5555,SF_TCP_NODELAY | SF_IO_NONBLOCK) == 1) { printf("TCP Socket open!\n"); } else { printf("TCP Socket NOT open!\n"); } } In the body of the infinite loop of the main function, I do this: for(uint16_t i = 0; i < sizeof(sock_n); i++) { httpServer_run(i); } In addition, in Carmine Noviello's book on stm32 microcontrollers, in the chapter on the http server, it was said that periodically I have to call the httpServer_time_handler function for the server to work correctly. I initialized the timer, and when it is interrupted, I call a callback function containing the instruction I need.: void MySysTickCallback(void) { httpServer_time_handler(); } Interrupt: void TIM1_CC_IRQHandler(void) { HAL_TIM_IRQHandler(&htim1); MySysTickCallback(); } I have briefly described my problem, and I am asking for help. I am attaching my project for CudeIDE to the post. Take a look at it, please. I really hope that together with you I will be able to complete my bootloader project, which will be able to expose the firmware over Ethernet.
