Problem to initilizate W5500

Question

Hi! I am new using W5500, and I’m using it with microprocessor of renesas, specifically the one, and I am using the e2 studio to program it. I want to do a webservice but I don’t know much about networks. I’m follow next link because STM IDE it’s to similar to e2studio Carmine Noviello - A blog about programming and electronics – 28 Aug 15 Adding ethernet connectivity to a STM32-Nucleo - Carmine Noviello - A blog... One drawback of the Nucleo ecosystem is the lack of a version with ethernet connectivity or a dedica I’m using iolibrary for W5500 and my problem is when I set the information. I’m using logic analyser and I debug the program step by step in function wizchip_setnetinfo, specifically in setSHAR, setGAR, setSUBR and setSUBR void wizchip_setnetinfo(wiz_NetInfo* pnetinfo) { setSHAR(pnetinfo->mac); setGAR(pnetinfo->gw); setSUBR(pnetinfo->sn); setSIPR(pnetinfo->ip); DNS[0] = pnetinfo->dns[0]; DNS[1] = pnetinfo->dns[1]; DNS[2] = pnetinfo->dns[2]; DNS[3] = pnetinfo->dns[3]; DHCP = pnetinfo->dhcp; } I could see in MOSI channel that it is sending 0x00 WIZNET11919×764 126 KB In function wizhip_getnetinfo, I obtain all parameters as 0 (ip, gateway, mac…) I’m using this code: { uint8_t retVal, sockStatus; int16_t rcvLen; uint8_t rcvBuf[20], bufSize = {2, 2, 2, 2}; uint8_t codigo[1]; reg_wizchip_cs_cbfunc(cs_sel, cs_desel); reg_wizchip_spi_cbfunc(spi_rb, spi_wb); wizchip_init(bufSize, bufSize); wiz_NetInfo netInfo = { .mac = {0x6c, 0xfd, 0xb9, 0x52, 0xf9, 0x38}, // Mac address .ip = {192, 168, 1, 195}, // IP address .sn = {255, 255, 255, 0}, // Subnet mask .gw = {192, 168, 2, 1}}; // Gateway address wizchip_setnetinfo(&netInfo); wizchip_getnetinfo(&netInfo); // Open socket 0 as TCP_SOCKET with port 5000 if(((retVal = socket(0, Sn_MR_TCP, 5000, 0))) == 0) … } I’m including libraries and I’m starting SPI before this code run. Also, I use cs_sel, cs_desel, spi_rb and spi_wb according to the tutorial of Adding ethernet connectivity to a STM32-Nucleo and my configuration To configure netinfo, I use cmd-> ipconfig/all to see information but I’m not sure if this information is correct. My questions are: How I can know netinfo is correct? Why it didn’t send the correct information across logic analyser? Why I’m receiving net inforamtion as 0? I’m student and I’m trying to learn about this kind of networks, and I’m searching in forum about this problem, but I can’t know why it is falling. I would appreciate any possible help.

I think that SPI connection does not work. Please check Configuring SPI Interface.

I added a callback function to my code, and now, if I debug step by step these lines: wizchip_init(bufSize, bufSize); wiz_NetInfo netInfo = { .mac = {0x6c, 0xfd, 0xb9, 0x52, 0xf9, 0x38}, // Mac address .ip = {192, 168, 1, 195}, // IP address .sn = {255, 255, 255, 0}, // Subnet mask .gw = {192, 168, 2, 1}}; // Gateway address wizchip_setnetinfo(&netInfo); wizchip_getnetinfo(&netInfo); I obtain this in the analyser: First image is what I obtain for wizchip_init(bufSize, bufSize); Second image is what I obtain for wizchip_setnetinfo(&netInfo); Third image is what I obtain for wizchip_getnetinfo(&netInfo); Ethernet31920×3304 454 KB Also, when I execute wizchip_getnetinfo(&netInfo); and watch the result,I obtain next results in netinfo: mac={0,0,2,2,3,3} ip={0,0,2,2} sn={0,0,2,2} gw={0,0,2,2} I read in other post that obtain 0x01,0x02,0x03 in MISO is a good conection, but my wiznet return bad info. I don’t know if it could be a bad clock configuration. I would appreciate any possible help.

Hi!! I solucionate my issue. I added a little delay in my code (100 us) after read and write and I see clearly the comunication in the analiser. Now, I can ping my chip and get OK
