Dear Vincenzo,
In message QrD9VP_oWKoLFr3jCKh8r0KLut7JWZZeSNUReP5RgGYhSJJZ-JOLzruPOyGAIuh43ZZwemF7pHPH2oHo4NpcLJbM5yJkWOSs6CwmVJbCo4w=@protonmail.com you wrote:

I tried to use different -net options in qemu but the problem is always the same.
And from the u-boot source code I have edited the board file qemu-ppce500.c in order to have a few ENV variables (since I can't save any env variables from the running U-boot in qemu).
ethact=eTSEC1 ethprime=eTSEC1
I doubt that there is a qemu emulation for the TSECs...
The image is compiled using of course: qemu-ppce500_defconfig.
What am I doing wrong? Is it even possible to initialize the Ethernet port?
Well, if you check the configuration you will see that it has a plain
# CONFIG_TSEC_ENET is not set
so the TSECs will indeed not work. But then, there is
CONFIG_E1000=y
It would have been helpful if you had included the actual boot messages of your system. There should be some E1000 network interface visible...
Best regards,
Wolfgang Denk
