Either I’ve really screwed up my circuit design, I have dozens of bad 32,768 crystals, or I’m not understanding something with regards to getting the real time clock to work on the G30.
I’ve assembled 4 prototype boards now and I keep expecting to see a resonating oscillator on those lines, on the scope, but so far, absolutely nothing. Lines are just held low. VBAT has a 3.3v cell and 3.3v rail driving it through a schotky, I’ve got the crystal’s supplementary capacitors figured out (it’s 7pf and I arrived at 10 for my caps; (7-2)* 2 = 10 for c1 /c2.)
But that oscilator is not working, at all.
Is there something I have to do in code to get it to start working?
Or do I have to go back to the drawing board and figure out what I did wrong on my design?
