Link does not come up (W5500-EVB-Pico)

Question

I have tried the firmware here: github.com wiznetmaker/Hard_wired_WIZNET5K-Micropython/blob/main/firmware/W5500_EVB_PICO_Hardwired.uf2 This file is binary. show original and this one: W5500_EVB_PICO-20231005-v1.21.0.uf2 Using this code I should get the link come up and be able to ping the device… spi = SPI(0, 2_000_000, mosi=Pin('GPIO19'), miso=Pin('GPIO16'), sck=Pin('GPIO18')) nic = network.WIZNET5K(spi, Pin('GPIO17'), Pin('GPIO20')) # spi,cs,reset pin nic.active(True) nic.ifconfig(('192.168.0.18', '255.255.255.0', '192.168.0.1', '8.8.8.8')) while not nic.isconnected(): time.sleep(1) print(nic.regs()) However I just stay in the loop waiting for isconnected Here are the register dumps: Wiz CREG: 0000: 00 00 00 00 00 00 00 00 00 02 77 f3 5c 62 9a 00 0010: 00 00 00 00 00 00 00 00 00 07 d0 08 28 00 00 00 0020: 00 00 00 00 00 00 ff ff 00 00 00 00 00 00 ba 00 0030: 00 00 00 00 00 00 00 78 25 04 00 00 00 00 00 00 0040: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Wiz SREG[0]: 0000: 84 00 00 42 c0 00 ff ff ff ff ff ff 00 00 00 00 0010: 00 00 05 c0 00 00 80 00 00 00 00 00 00 00 10 10 0020: 40 00 09 92 09 92 00 00 00 00 00 00 ff 40 00 00 Wiz SREG[1]: 0000: 00 00 00 00 00 00 ff ff ff ff ff ff 00 00 00 00 0010: 00 00 00 00 00 00 80 00 00 00 00 00 00 00 00 00 0020: 00 00 00 00 00 00 00 00 00 00 00 00 ff 40 00 00 Wiz SREG[2]: 0000: 00 00 00 00 00 00 ff ff ff ff ff ff 00 00 00 00 0010: 00 00 00 00 00 00 80 00 00 00 00 00 00 00 00 00 0020: 00 00 00 00 00 00 00 00 00 00 00 00 ff 40 00 00 Wiz SREG[3]: 0000: 00 00 00 00 00 00 ff ff ff ff ff ff 00 00 00 00 0010: 00 00 00 00 00 00 80 00 00 00 00 00 00 00 00 00 0020: 00 00 00 00 00 00 00 00 00 00 00 00 ff 40 00 00 None Why does the link not come up…??

Keith_Marston: Why does the link not come up…?? How do you know link is not up? What else (other than running some code) did you do to get it?

Eugeny · Answer

Try crossover cable. W5500 is not MDIX, unless switch supports it. Or just try another switch/connect directly to the PC.

Keith Marston · Answer

Connecting directly to the pc I would expect to need a crossover cable But I have board to switch on a standard straight through cable as you would for any device If the board does not work like that then it just needs to be in the bin!
