Ethernet Link Down--ESP32S3 with W5500 to establish an Ethernet connection (IDFGH-13341)

[Chillimeat]

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

I am currently using ESP32S3 with W5500 to establish an Ethernet connection, using version V5.3. The current issue I'm facing is that the network card repeatedly restarts and shuts down. Even when it starts up normally, it fails to communicate with other hosts

The log information is as follows:

Please try esp_base_mac_addr_set() and esp_netif_set_mac() instead of esp_eth_ioctl.

I experienced this on v5.0 and the symptom was "Ethernet HW Addr 00:00:00:00:00:00"

I also experienced "w5500.mac: emac_w5500_transmit(n): free size (0) < send length (k)" when my pins were incorrectly connected. You'll need to verify tx & rx are correctly connected and your clock speed.

Change your clock speed to ".clock_speed_hz = SPI_MASTER_FREQ_8M;"

Add ".flags = SPICOMMON_BUSFLAG_MASTER | SPICOMMON_BUSFLAG_SCLK | SPICOMMON_BUSFLAG_MISO | SPICOMMON_BUSFLAG_MOSI" to the spi_bus_config_t.
Change transfer speed to ".max_transfer_sz = 0".

Remove the line "phy_config.phy_addr = 1;"

Please try esp_base_mac_addr_set() and esp_netif_set_mac() instead of esp_eth_ioctl.

@DarmorGamz Could you please elaborate what is the issue? This exact scenario is tested in CI for all supported Ethernet SPI modules.

[kostaond]

@Chillimeat how is your W5500 connected to ESP32? Do you have custom board or is it connected just via jumper wires? What W5500 board do you use?

[Chillimeat]

@kostaond
Thank you very much for your attention. I am using DuPont wires for connection, and I have attached the relevant pictures.

[Chillimeat]

Please try esp_base_mac_addr_set() and esp_netif_set_mac() instead of esp_eth_ioctl.

@DarmorGamz Could you please elaborate what is the issue? This exact scenario is tested in CI for all supported Ethernet SPI modules.

I also used a separate 5V power supply for power.

[kostaond]

It seems you have some issues with SPI communication. Double check (or triple check :)) SPI configuration, that the connection is correct and use wires as short as possible (max 10cm) with matching length. You can also try to lower the SPI frequency to 8 MHz.

[kostaond]

@Chillimeat any update? Have you been able to resolve the issue?

[kostaond]

Closing the issue due to lack of feedback from reporter.

[MAE-91]

I am facing the same issue . Have you found the root cause?

[kostaond]

@MAE-91 could you please be more specific? How is your W5500 connected to the ESP32? If it's module, what module do you use? What is behavior you observe? What IDF version? etc...

[MAE-91]

I am currently benchmarking to replace my existing Ethernet solution, which uses 10 pins, with an SPI Ethernet solution to free up more GPIOs. The example works when I use the ESP devkit, but it fails on my custom board that I manually reworked. I am using a WIZ850io module connected to a breadboard, and it is wired to my board with manual soldering.

the error :
w5500.mac: W5500 version mismatched, expected 0x04, got 0x00
w5500.mac: emac_w5500_init(795): vefiry chip ID failed
esp_eth: esp_eth_driver_install(228): init mac failed

idf version 5.3.2

[kostaond]

Seems like hardware issue... Triple check that your SPI MOSI/MISO/SCLK configuration align with the hardware and signal is present at both source and sink pins. Try to decrease SPI frequency to e.g. 8 MHz. Make sure the WIZ850io is functional or use another piece if you have such option.

[MAE-91]

I have a question. is it possible to use W5500 as a PHY only? if not , Do you know any PHY chip that works with esp32 with SPI ?

[kostaond]

It's not possible to have just PHY connected to MAC over SPI. MAC and PHY communicate over MII/RMII interface (ESP32 supports both but RMII is preffered and tested). See https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-reference/network/esp_eth.html#configure-mac-and-phy for more information.
