I have a copy of a custom design (built over 30 which work) where the RTC crystal stopped oscillating (it did work for a while, and now it is not). I have replaced the crystal to no effect. When I probe the crystal pins, the one connected to XTAL32 is just slightly above ground, and the EXTAL32 pin is around 1V. When we replaced the crystal, the solder balls we inspected on the K60, and looked OK.
Any suggestions on what could be going on?
