Hi, I had previously been asking for help with a flashcart I was building that eventually became a long issue to the point that it was better to be here. Anyways, the rtc isn’t working at all, it won’t move ahead in time at all, it just stays at the time that was set. I’ll try to post the data on the oscillator I used in case it isn’t the right one. If it is, then please let me know if I’m doing something wrong in regards to the way on soldering it in.
#MBC30 Flashcart Clock Crystal not working.

Ok crap, it’s just the Comimark 32.768 KHz 32768HZ Crystal Oscillator 2 x 6 mm. It doesn’t list if it’s R26 or 12.5pF.
Ok, can someone let me know if ±20ppm is ok as an alternative ppm? I know it’s supposed to be 10ppm, but it’s the only part on digikey that matches all the other requirements.

That's just accuracy, which shouldn't affect the general functionality

Oh thank god, in that case I’ll just order the ones on digikey.
Shit, they’re out of stock.

Make sure C4, C5, and R1 are properly soldered. Also the pins on the top edge of the MBC30 chip
Actually, it looks like pins 16 and 17 of the MBC30 are for the crystal, so check those

Yup, just checked them and, I’m pretty sure Jack said that floating legs are the bane of his existence? Yeah, I agree, fuck floaters.
