Hi NXP support team:
Recently we encountered a tricky problem that when we removed the wakeup source for FS26 it cannot power off occasionally. We found the VBOS voltage was quite weird. Compared to the normal situation VBOS voltage jumpped to about 5V and quickly went down. I post the capture of measurement for these signals from logistic analyzer. Please refer to this and help us analyze this problem. In the below picture FS0B_VBOS is the voltage of VBOS there is a wave after FS26 enter into LPOFF status than all the other voltage that supplied by FS26 go wrong and FS26 cannot control the system power on again. I want to know the reason why VBOS act like this ?

Below picture is the wave that FS26 powered down in a right sequence. All the voltages were normal ,VBOS voltage didn't jump and the system went power down smoothly.
