The SWOUT and VBUS_OTG of STPMIC1 have no output

I used STPMIC1APQR to power STM32MP151AAC3. At present, the BSTOUT of STPMIC1 has an output voltage of 5.2V, and BSTOUT is short-circuited to SWIN, but when the internal switches pwr_sw and pwr_usb_sw of the STPMIC1 are turned on, SWOUT and VBUSOTG are always not output. What could be causing this problem?
