Ah! I missed that part. That's very important infoI have to again note that I'm using the Netduino Plus 2 firmware with the home brew stm32mini.
Okay, then two things:
1. If you do come back to this issue, can you test it on actual Netduino hardware--to see if you get the same issue?
2. Have you tested this using the Netduino 2 firmware instead? Not having the Ethernet chip, etc. on board could throw off the runtime, internally.
