I built the UHD example, gpio.cpp (no modifications), and ran it on my N310 to
start experimenting with the GPIO. It returned with two failures:
Testing ATR TX output...fail:

Bit 10 9 8 7 6 5 4 3 2 1 0

2 tests failed
Done!
Is this something that I should be concerned about?
If I compile and run the same example with my X310, everything passes.
Here's the uhd_config_info --print-all from my N310:
