STM32-E407 - there is no carrier ethernet with crossover cable

[anotherbrick]

hello dear forum,

I am trying to ethernet connect E407 board direct to PC with crossover cable

however the activity and link status LEDs does never turn ON after reset

with standart cable - when connected via modem the LEDS are ON only after 1 minute after reset

what can I do next ?

thank you

Strange behavior. Maybe related to the Ethernet cable or the power supply. How do you power the board?

This is the cable that I used to connect to a modem/router: https://i.imgur.com/KSn68wL.jpg

We tested this scenario - even if we wipe any software from the board - the LEDs work immediately.
