Help me ragrding w5500

Question

I am using wiznet w500 io module purchased from ebay . I am interfacing with arduiono atmega2560 . WHEN I CONNECT THE MODULE windows xp show connected and both led are ok and also one of led start blinking but stop blinking after some time it stop blinking . ping is not working is module is damged or some thing esle as arduiono code show sever at 0.0.0.0 i am using latestes arduion libary. my connection as follwo MISO → MISO MOSI ->MOSI CS > LOW TIED TO GROUND RESTET LEFT ALONE SCK → SCK WHAT IS PROBLEM

Hi Sorry to late your answer you checking the W5500 datasheet. And I need you code. you using arduino example code? there is 3 fact. First, module broken. → This problem is probably not Second, you connected LAN port ? and you check link LED blink? third, SPI signal matching is wrong. check to below code. below code is SPI each signal part matching code // CLK pin enable GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP; // External clock //MISO pin enable GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING; // Master in Slave out -> Floating = high Impedence //MOSI pin enable GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP; // Master Out Slave in (Slave is external) //CS pin enable GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; // GPIO_Mode_Out_OD - open drain (open collect) -> It's want Pull up resistor //RESET pin enable GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; // M3 (Master) -> W5500 (Slave) //INT pin enable GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPU; // internal Pull up Thank you
