# FORCE\_USB\_BOOT Source: [https://docs.qualcomm.com/doc/80-PV086-5P/topic/force-usb-boot.html](https://docs.qualcomm.com/doc/80-PV086-5P/topic/force-usb-boot.html) During development or factory production, a boot from the primary USB 3.1 port can be forced by using GPIO\_132. FORCE\_USB\_BOOT (GPIO\_132) always takes precedence, regardless of the state of the BOOT\_CONFIG GPIOs or FAST\_BOOT\_SEL fuses. The FORCE\_USB\_BOOT is checked first during the boot device detection, prior to BOOT\_CONFIG GPIO states. GPIO\_132 = 1 forces the QRB5165 device to boot from the primary USB 3.1 port. Figure : 1.
