I tried and this is my output:

17:31:49.374 ->

17:31:54.104 -> [EM] dns1IP = 0.0.0.0 , dns2IP = 0.0.0.0
17:31:56.052 -> ETH Connected

I think it's not enough output, it should also say local ip etc .

These PIN number work with the EthernetWebServer example so they should be correct.

Hi @avanderhoest

Try to use pin assignment defined in the board package um_tinys3 pins_arduino.h

static const uint8_t SS    = 34;
static const uint8_t MOSI  = 35;
static const uint8_t MISO  = 37;
static const uint8_t SCK   = 36;

by changing these lines

  // For W5500
  // Optional values to override default settings
  // Don't change unless you know what you're doing
  //#define ETH_SPI_HOST        SPI3_HOST
  //#define SPI_CLOCK_MHZ       25
  
  // Must connect INT to GPIOxx or not working
  //#define INT_GPIO            4
  
  //#define MISO_GPIO           13
  //#define MOSI_GPIO           11
  //#define SCK_GPIO            12
  //#define CS_GPIO             10

  #define CS_GPIO             34

Beware that INT is important. Without it, the library won't work

Hi @avanderhoest

If you're using WT32-SC01-PLUS, then I think you can use as you're using, according to

---

  // For W5500
  // Optional values to override default settings
  // Don't change unless you know what you're doing
  #define ETH_SPI_HOST        SPI3_HOST
  #define SPI_CLOCK_MHZ       25
  
  // Must connect INT to GPIOxx or not working
  #define INT_GPIO            13
  
  #define MISO_GPIO           21
  #define MOSI_GPIO           14
  #define SCK_GPIO            12
  #define CS_GPIO             11

If still not working, try

• other Ethernet cables, routers as LwIP W5500 Ethernet is more demanding with speed, DMA, interrupt, etc
• W5500 with another ESP32_S3, such as UM-TinyS3 to be sure it's working with LwIP library
• Check the wiring, especially INT. Modify the INT pin to avoid conflict, etc
• Using SPI2_HOST instead of SPI3_HOST
• separate 3.3V power supply for W5500

If not, I have no idea as I don't have the same WT32-SC01-PLUS to try. Too many new versions of boards now.

You're on your own or ask the WT32-SC01-PLUS manufacturer for support.

Beware that Ethernet and SD card can't use the same SPI in new ESP32

Hi @avanderhoest

Check the new AsyncWebServer_ESP32_SC_W5500 library, designed specifically for ESP32_S3 (and in the future will support ESP32_S2 and C3)

Tested OK on

Yessssss! It works with this lib!! Thank you!!
