My code for W5500 stucks in the socket() function

Question

Hi, I want to transfer data by connecting the W5500 module to the STM32H7 board. I wanted to test it before starting my project. My test code is as follows. My code gets stuck and does not progress in the socket() function. What could be the problem? I believe I have made the GPIO connections correctly. I used SPI5. What should i do? /* USER CODE BEGIN Header */ /* USER CODE END Header / / Includes ------------------------------------------------------------------*/ #include “main.h” /* Private includes ----------------------------------------------------------/ / USER CODE BEGIN Includes */ #include “socket.h” #include “wizchip_conf.h” #include <string.h> #include “loopback/loopback.h” /* USER CODE END Includes */ /* Private typedef -----------------------------------------------------------/ / USER CODE BEGIN PTD / int sn = 0; #define mydata “test

Anonimo: uint8_t bufSizeTx={2,2,2,2}; uint8_t bufSizeRx={2,2,2,2}; W5500 has 8 sockets. Before doing anything else try reading the PHYCFGR register to prove you read 0x04.
