You have to compile the code with:

MICROPY_PY_WIZNET5K = 5500
MICROPY_PY_LWIP = 1

Don't forget to call 'make clean' before recompile.

P.S:: For convenience, I placed an image here: https://hidrive.ionos.com/lnk/I4Ymqmvs

Thank you.
I was tested this module with arduino, the same result, I thin that this module is broken.
I will be order new one and testing again.

I was tested other Ethernet Module with Wiznet 5500. All is working.


This module NOT WORKING with MicroPython with STM32F4Disc and PyBoard v1.1 (and not working Arduino)

I received a new module from another vendor. the left module works, the right module does not work at all.

They are similar,. but not identical. Track routing seems more critical on the right hand device, like under the two C's right to the "popctrl" label, and in the upper right corner the tracks that connect the W5500 to the soldering pins of the module.

(MicroPython v1.17-74-...)
if I compile with:
~/micropython/ports/stm32 $ make MICROPY_PY_WIZNET5K=5500 MICROPY_PY_LWIP=1
there is an implicit declaration of function.
This is all the same for all Boards.

By compiling without the MICROPY_PY_LWIP=1
runs OK an the Hardware is included

has anyone an Idea for me to fix my Problem?

I also encountered the same problem, compilation error

Download the package of 1.17 + daily update package from the official website, and the compilation will report the above error
If you clone directly from GitHub, the compilation is correct

I think you mentioned it but didn’t update the diagram. For SPI communications you don’t cross the signals like you would for a UART. MISO goes to MISO, MOSI goes to MOSI.

Did you find a solution for this issue? I'm struggling with a STM32F411 board.
