SOF-file works correctly, POF-file does not

I made the simplest of the simplest NIOS II

applications: a LED that blinks endlessly. I

have a SOF- and POF-file created by Quartus

Prime 16.0.0.

Programming the SOF-file and running the

NIOS II application results in a continuously

blinking LED. However, programming the

POF-file and power cycling the MAX 10

development board gives a LED that blinks

for about one second. After that it stays

lit.

Any clues?

[ Solution: apparently it is due to printf statements

in the NIOS C-code. Removing them solved the problem. ]

Thanks,

Jos
