Micropython wiznet5k.activate does not work in 1.21

Question

I bought a W5100S ethernet hat that I want to combine with a raspberry pico W. I wanted to run the example from the wiznet’s git to be able to ping the pico: from machine import Pin,SPI import network import time time.sleep(5) led = Pin(25, Pin.OUT) #W5x00 chip init def w5x00_init(): spi=SPI(0,10000, mosi=Pin(19),miso=Pin(16),sck=Pin(18)) nic = network.WIZNET5K(spi,Pin(17),Pin(20)) #spi,cs,reset pin print(‘b’) nic.active(True) print(‘e’) nic.ifconfig((‘192.168.1.20’,‘255.255.255.0’,‘192.168.1.1’,‘8.8.8.8’)) while not nic.isconnected(): time.sleep(1) print(nic.regs()) print(nic.ifconfig()) def main(): w5x00_init() while True: led.value(1) time.sleep(1) led.value(0) time.sleep(1) if name == “main”: main() However the pico becomes totally unreachable with either thonny and rshell. Even reloading the firmware is not enough. I tried to find out, and apparently the line that was problematic is: nic.active(True) I tried aswell several firmwares and what I found out is that the latest version of micropython was not working, even downloaded from the micropython website: https://micropython.org/resources/firmware/W5100S_EVB_PICO-20231005-v1.21.0.uf2 Version 1.20 was working: https://micropython.org/resources/firmware/W5100S_EVB_PICO-20230426-v1.20.0.uf2 Do we have any idea why? My goal would be to be able to use the wifi to create an hotspot that connect to the network I have with the ethernet.

hello. Unfortunately, we don’t yet have firmware that supports Pico W and W5100S Ethernet simultaneously in the latest version. We don’t know how it could have worked in version 1.20, but we think you should be able to run your project using the 1.20 version of the firmware that works. Thank you. micropython.org MicroPython - Python for microcontrollers MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimised to run on microcontrollers and in constrained environments. micropython.org MicroPython - Python for microcontrollers MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimised to run on microcontrollers and in constrained environments.

On the integrated board (W5500-EVB-Pico the reset and SPI-sck are on different pins…?? Having said that - I can’t get mine to work - runn uPy W5100S_EVB_PICO-20240222-v1.22.2.uf2 from machine import Pin,SPI import network import time #W5x00 chip init def w5x00_init(): spi=SPI(0,10000, mosi=Pin('GPIO19'),miso=Pin('GPIO16'),sck=Pin('GPIO18')) nic = network.WIZNET5K(spi,Pin('GPIO17'),Pin('GPIO20')) #spi,cs,reset pin print(nic) nic.active(True) print(nic) nic.connect() # nic.ifconfig((‘192.168.1.20’,‘255.255.255.0’,‘192.168.1.1’,‘8.8.8.8’)) while not nic.isconnected(): time.sleep(1) print(nic.regs()) print(nic.ifconfig()) w5x00_init() This just hangs on nic.active() But where do you specify the INTn pin from the network interface?
