Hi, snowflake.
The WIZ550web’s firmware is consist of two parts, application boot and application.
Setting the D8 pin (GPIO_Pin_12, GPIOC = SW0 on EVB) to High state and reboot the WIZ550web, the device go into Boot mode. This function for firmware update and firmware recovery when a problem occurred. (malfunction of the application firmware)

Please utilize the D8 pin as a boot mode switching pin only and the other input pin in the board applying to your applications.
