Shouldn't the lines 8 and 9 in the "init_samd51.c" file be commented out?
// Output GCLK0 to Metro M4 D5. This way we can see if/when we mess it up.
PORT->Group[1].PINCFG[14].bit.PMUXEN = true;
PORT->Group[1].PMUX[7].bit.PMUXE = 12;
It's just that these lines will cause the SAMD51 to output GCLK0 at 48MHz on port pin PB14, whenever the board's in bootloader mode. This is digital pin D5 on the Metro M4.
