Depending on boards we use some ports cause a shutdown after setting mode for pin, like D16.mode("output").
Testing was done to check speed of different solutions for LED-Matrix(32x64).
Started with a board from Watterott, everything worked fine.
Switching to another board reset with same configuration.
Problem could be drilled down to usage of IO16 and IO17.
D16.mode("output") and I've got a reset.
Most boards don't have pins for IO16 and IO17, so be careful, not to use them accidently
