# Boot from USB

You can close the BOOT jumper on the ConnectCore 6UL SBC Pro to force the i.MX6UL to boot from the source programmed in the one-time-programmable (OTP) bits. If the boot configuration OTP bits are not programmed, the CPU falls back to booting into USB debug mode.

The default state for the jumper is open, which configures the i.MX6UL to boot from board settings (boot from NAND flash). If the NAND flash doesn't contain valid firmware, the i.MX6UL also falls back to booting into USB debug mode. You can use this functionality for recovery purposes, such as if the bootloader is erased or cannot boot.

For more information about boot mode configuration, see the ConnectCore 6UL Hardware Reference Manual.
