I made some 1062 motherboards with reference to the development board, and used the external battery 2032 to supply power to VDD-SNVS-IN. 80% of the motherboard K7 can output 1V voltage and start with normal power. 20% of the mainboard K7 output is 0V, and cannot be started normally. Re-buckle the battery and install it again, and there is no follow-up. 20% of the motherboard can not start no matter how it is powered on, as if the chip is stuck inside, K7 seems to be clamped at 0V can not get up, May I ask the technology has encountered this problem
