Portenta H7 + Micropython = No static IP over Ethernet

Hardware Portenta Portenta H7

For me, when trying Micropython w/ OpenMV, the ethernet stack does not work at all, I always get an DHCP timeout.

When trying vanilla Micropython 1.23, I can only get a DHCP lease, but I can't set a static IP address.

I've added all technical details in a github issue here, but I'm requesting some help from the Arduino side to fix this bug.

Thank you in advance!

Hi @razvanphp. I see the MicroPython maintainers requested you to notify Arduino of this for administrative purposes:

let Arduino know about the issue and they will assign us to fix it.

Please do that by submitting a ticket through the contact form here:

https://www.arduino.cc/en/contact-us

The people at Arduino who are involved in the MicroPython development don't necessarily monitor every forum post, so they might not see your topic here.

Thank you @ptillisch, I did that as well.

In the meantime, mistery solved!

It seems that the order of lan.active(True) and lan.ifconfig([tuple]) matters, in the sense that calling active resets the interface to DHCP:

I will try to contribute this back to the documentation.
