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.
