ESP32S3 with W5500 build

[MikePolynin]

Hello everyone

Im trying to build a micropython firmware for ESP32S3 32Mb with W5500 ethernet module but its going wrong.
Build with ESP-IDF 5.1.1 and with the latest micropython from Git repo.

Turn on W5500 module support thru 'component config -> ethernet -> support spi to ethernet module' in idf.py menuconfig.
And when i run make command after i get message:
HINT: Macro ETH_W5500_DEFAULT_CONFIG now accepts both SPI host and SPI device related configuration. The SPI-Ethernet Module initialization has been simplified to allocate an SPI device internally so the configuration structure requires the related configuration.
Please refer to the Networking migration guide, section SPI-Ethernet Module Initialization, for more details.
Without W5500 module support building is ok.

What shall i do? What`s wrong with settings?

Look at PR #12736, which re-enables support for the W5500 with esp-idf v5.x. Tested with a generic ESP32 device and esp-idf v5.0.2. The changes are not device-specific. So it should work with an esp32S3 as well. esp-idf v5.0.2 is the version used for MicroPython at the moment. Building with v5.1.1 may work, but is not tested yet.

If i try esp-idf 5.0.2 version - result is the same

Hello

So i decided the problem with the building by using clean virtual machine.
As i find out problem was in flashing by Thonny.

All submodules are fine.

I try build with a make MICROPY_PY_NETWORK_WIZNET5K=5500 BOARD=ESP32_GENERIC_S3 BOARD_VARIANT=SPIRAM_OCT and it is ok
but when i try run nic = network.WIZNET5K(machine.SPI(1), pyb.Pin.board.X5, pyb.Pin.board.X4) after import network
i get an error AttributeError: 'module' object has no attribute 'WIZNET5K'

Can you give some advice please?

Thonny again! It's not WIZNET5K, and your example is for the PybBoard V1.1. At an ESP32. A typical start sequence would be:

import network
import machine
import time
spi = machine.SPI(1, sck=machine.Pin(18), mosi=machine.Pin(21), miso=machine.Pin(19))
nic = network.LAN(phy_type=network.PHY_W5500, spi=spi, phy_addr=1,
                    cs=machine.Pin(5), int=machine.Pin(4))

nic.active(1)
while not nic.isconnected():
    print(".", end="")
    time.sleep(0.25)

You have to set the Pin numbers following the connections you have.

Meanwhile the W5500 branch has been merged into the master. So you do not have to use the PR, and from tomorrow on it should be available in the v1.22 preview build.

Thank you very much for your answers and spending time!

My board now connect to the w55500

I tried compiling the firmware using make MICROPY_PY_NETWORK_WIZNET5K=5500 BOARD=ESP32_GENERIC_S3 and also tried adding CONFIG_COMPILER_OPTIMIZATION_SIZE=y CONFIG_ETH_SPI_ETHERNET_W5500=y int sdkconfig.board as discussed here: https://github.com/orgs/micropython/discussions/11474
Both times the sample code from @robert-hh did run, but both times it got stuck printing dots. Looking with a Oscilloscope, I saw, that no SPI communication takes place. If I put in a spi.write statement, spi communication is taking place. Do you have any idea, what I could try next? I am using the micropython release 1.22.2 from February, so the PR should already be included.
