I am experiencing failures of the LSE oscillator on STM32F427VIT6 during thermal cycling.
I have an ESC ECS-.327-CDX-1082 32.768KHz crystal on the LSE of an STM32F427.I have read and followed AN2867.All of the boards produced so far have had the oscillator come up initially.All of the boards subjected to thermal cycling (-20°C to +70°C) h...
