NAND memory. However, it is possible to boot from USB through a jumper (J10). This jumper forces 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. ... -
Page 14: Boot Configuration
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. ... -
