Boot from USB

You can close the USB mode jumper on the ConnectCore 6UL SBC Express 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 boot
loader is erased or cannot boot.
For more information about boot mode configuration, see the
Reference Manual.
