Hello,

I'm experiencing an issue with a STM32F101 using an 32.768kHz LSE.

The LSE being used is the 7pf variant shown in the link below with 9pf caps as CL1 & CL2

The problem is that periodically(every 25 to 50 boards) the LSE does not start.

Does anyone have an idea what might be happening here?
