Didn't you say the ZYNQ ran hot - too hot to put your finger on?
What did you do to cool it down?

That could be a reason, yes. E.g. some process trying DHCP on an ethernet even though there is no link-up indication. Or something doing a DNS resolve without checking if there even is a network.

Yes, over 120C, close to the default internal shutdown temp.
Working really hard (lots of logic clocked at 125 MHz) the 7020 chip got real hot. The fix is to epoxy a pin-fin heat sink on top, and blow air straight down on that, sorta like an Intel CPU.

The microZed board has mounting holes for a fan, but they line up with the hole centers of no known fan. So we had to make an adapter plate.

My latest board (not a microZed) uses a Zynq, but we got the fan holes right. Maybe we won't need the fan, but the hooks are there.

I picked up six used 55 gallon drums for free, yesterday. An oil distributor was shutting down their local office. Five are 'closed head' which are what you need, to convert into a wood stove. Northern Tool wanted about $75 each for new drums.
