Board

M5Stack AtomS3 + ATOM_PoE

Device Description

See schematic of AtomPoE
AtomS3
N.B. the pins on the AtomPoE board refer to an ESP32 Atom module.
The AtomS3 uses an ESP32-S3 and thus has different GPIO pins.

Hardware Configuration

  • SPI CLK: GPIO-5
  • W5500 CS: GPIO-6
  • SPI MISO: GPIO-7
  • SPI MOSI: GPIO-8

INT & RST set to -1

5-pin row on the Atom PoE board:

  • 3V3
  • CLK
  • CS
  • MISO
  • MOSI

Description

There are boards with a W5500 SPI Ethernet controller which do not have the INT and RST pin connected.
However in the ETH::beginSPI function, this will be rejected as it checks for those pins.

To overcome this check, this function can be changed to something like this:

bool ETHClass::beginSPI(eth_phy_type_t type, uint8_t phy_addr, int cs, int irq, int rst, 
#if ETH_SPI_SUPPORTS_CUSTOM
    SPIClass *spi, 
#endif
    int sck, int miso, int mosi, spi_host_device_t spi_host, uint8_t spi_freq_mhz){
    esp_err_t ret = ESP_OK;

    if(_eth_started || _esp_netif != NULL || _eth_handle != NULL){
        log_w("ETH Already Started");
        return true;
    }
    if(cs < 0 || 
	   (
#if CONFIG_ETH_SPI_ETHERNET_W5500
        (ETH_PHY_W5500 != type) &&
#endif
		irq < 0)){
        log_e("CS and IRQ pins must be defined!");
        return false;
    }
    ...

However even with those changes, I can't get the ETH.begin function to return true.
N.B. I do call the ETH.begin function with SPI as argument.
On M5Stack Core2 (ESP32) with W5500 base plate and on ESP32-C3 board wih DM9051 this does work perfectly fine.
But those setups have INT and RST wired to the ESP.
