is there any chance that this firmware could be ported to the Meraki MS220-8P? And if anyone has that switch could they give me the pinout of the (large) header in the center of the board? thanks
I would suggest that you create a new thread under the For Developers section.
You also might want to be willing to open and photograph your device, and have a serial cable available.
If it's not currently supported, you'll likely have to be the one to start.
