Power management

The BSTOUT pin of STPMIC1APQR already has a 5.2V voltage output, and the SWIN pin is directly connected to the BSTOUT pin, but SWOUT has no voltage output. what error will cause this problem?

First briefly introduce our motherboard. STM32MPU151AAC3 (361-pin TFBGA package) is used in our motherboard, and STPMIC1APQR is used in the power supply. At present, booting from Micro-SD card is normal, DDR3L and e.MMC are working normally. Issue : ...
