Hello Joey,

I retested ethernet on my board and it doesn't work there either.
Probably the problem is the irq controller implemented in the board's
FPGA being buggy. I already talked to my contact at Energy Micro about
that and they are aware of the problem, just didn't find the time yet to
address it. I just pinged the problem. (In the hope this ping works
better than the efm32's :-)

The workaround is to connect the phy's irq line to a gpio of the Gecko.
Then the FPGA is out of the loop. That's how we at Pengutronix did it
for our Embedded World demo back then.

Best regards
Uwe
