cannot established socket

Question

hi, i am trying to change the ip address of w5500 chip and the ip wont change. stays 192.128.64.0 every time i read it. moreover i cannot established socket stuck in this command. while(getSn_SR(sn) != SOCK_ESTABLISHED){}; i assume because of the ip ??? any suggestions

in addition i want to check the version of the chip via scope, this is look reasonable? CLK%20MISO1480×919 78.8 KB don’t pay attention to the noise i am checking this problem

maor: i am trying to change the ip address of w5500 chip and the ip wont change. stays 192.128.64.0 every time i read it. As you provide no details how you do it, I suspect you write to wrong registers when updating the IP address. I think you will need to reopen already open sockets to make the change effective, but I am not sure. maor: while(getSn_SR(sn) != SOCK_ESTABLISHED){}; Do you have any idea what the status you get when it is stuck? Your code is flawed, socket may have many other states after you request it to connect. maor: i assume because of the ip ??? Because you set something wrong in W5500 registers, or perform something wrong on the socket. maor: any suggestions Please refer to W5100 datasheet, it has very good explanation of managing sockets in chapter 5. maor: this is look reasonable? What is this? You did not provide signal names, what exactly you expect to see, and what we should check it against.
