关于ESP32+W5500，idf ethernet basic例程,SPI spi transmit failed

[thedawndawndawn]

求助，使用idf ethernet basic例程测试W5500时，出现一下问题该怎么解决

哪个版本的 IDF？是否针对例程有修改？拿到 ip 后做了什么动作？

[Ali.Akdurak]

Hey Hello,
I have the exact same problem. My ESP-IDF version is v4.3 I have applied three patches for W5500 fixes.

Subject: [PATCH] esp_eth: Fix w5500 to break from potentially infinite tx loop

The issue typically happens for link-down during Tx. Added two retry levels, one before checking the sanity of the w5500 phy register and another for the Tx done itself (if the device is in the sane state)

Closes https://github.com/espressif/esp-idf/issues/6233

Subject: [PATCH] esp_eth: Improve GPIO interrupt processing in w5500 driver

Increase the interrupt reassert level timing so the chances of missing
two consecutive events are minimal.
Enable only SIR_RECV interrupt event, so the SEND events are not used
for GPIO signal.

esp_eth: Recover the w5500 driver from missed io interrupt: If the GPIO interrupt is re-asserted too quickly it could be missed. If this happens the driver goes silent and never receives any data. Recover by periodic checks of the IO signal level

I have the exact same problem. My ESP-IDF version is v4.4.
Can anyone solve this problem, please?

[ESP_ondrej]

The original issue should have been fixed as stated at https://github.com/espressif/esp-idf/issues/6233.

However, similar symptoms can be observed when there is an issue with SPI bus HW connection. Could you please try to decrease SPI Clock speed and check your hardware design? How is your ESP32 is connected with W5500? Is is soldered on PCB or just via jump wires? If wires are used, make sure that all wires are short as much as possible and have same length.
