Ethernet W5500 with Teensy 4.1

[gonzales]

Hi!
I have working project with Teensy 3.5 and Ethernet shield WIZ850io. I use standart SPI port for connection. Now i try to use Teensy 4.1, but unfortunetly i cant starting Ethernet.
How i can see in pinout diagram Teensy 4.1 has the same SPI pins as Teensy 3.5.
Examples from Standart libraries dont work properly, teensy hang up while Ethernet.begin(mac, ip);
I tryed all libraries (Ethernet, NativeEthernet, QNEthernet) with same result.
I read this https://www.pjrc.com/store/wiz820_sd_adaptor.html#init and make reset, how it recomended, but still dont work.
Is it possible to use Ethernet shield WIZ850io with Teensy 4.1?

I forgot to write, that i dont have any pullup resistors, just direct connection between Tennsy and Ethernet shield using pins 10,11,12,13

Try to use my Ethernet_Generic or EthernetWebServer library

I'm using here OK, without any pull-up resistor, for either Teensy4.0 or Teensy4.1

@khoil-prog, thanks for the answer.
But not work for me.

This is same connection with Teensy 3.5

I try to use more degug information for function isW5500()

uint8_t W5100Class::isW5500()
{
  chip = w5500;

  ETG_LOGDEBUG("isW5500: detect W5500 chip");

  if (!softReset())
    return 0;

ETG_LOGDEBUG("isW5500 1");

  writeMR(0x08);
  
  if (readMR() != 0x08)
    return 0;

ETG_LOGDEBUG("isW5500 2");

  writeMR(0x10);
  
  if (readMR() != 0x10)
    return 0;

  writeMR(0x00);
  
  if (readMR() != 0x00)
    return 0;

  int ver = readVERSIONR_W5500();

  ETG_LOGDEBUG1("Version =", ver);

  if (ver != 4)
    return 0;

  ETG_LOGWARN("Chip is W5500");

  return 1;
}

So in monitor i can see [ETG] isW5500 1 and dont see [ETG] isW5500 2

Oh my God, I found it!!! Two pins were not soldered properly((((((((
It work fine!!!

Good to know.
