I'm trying to enable a 16 MHz crystal I have connected on an ATxmega256A3U. I
can get it to run okay using the internal 2 MHz, 32 MHz, and 2 MHz * 15 PLL
clocks.
But it doesn't work with the external oscillator using the following:
CLKSYS_Enable(OSC_XOSCEN_bm);
do {} while (CLKSYS_IsReady(OSC_XOSCRDY_bm) == 0);
CLKSYS_Main_ClockSource_Select(CLK_SCLKSEL_XOSC_gc);
CLKSYS_Disable(OSC_RC2MEN_bm | OSC_RC32MEN_bm | OSC_RC32KEN_bm);
The crystal isn't driven, and the loop to check to see if the oscillator is
ready never exits.
It's possible I damaged the xtal during reflow (the oven ran 20°C hotter than
it should). But I'm not sure I'm not missing some crucial step in software
first.
Any suggestions? Thanks!
