Multiple tests in the pyb directory fail on a NUCLEAO_F411RE:

• The pyb/adcall.py has hard-coded pins, some of which (A2&A3) overlap with the uart used for the REPL. This causes the test to fail and the board to become unresponsive to pyboard/run-tests.
• 6 tests failed: extint pin pyb1 rtc servo uart
