- When power is attached, the red and blue LEDs will turn on. The green LED stays in the off state.
- There is no power to HDMI or USB.
- BootROM scans for the bootloader at sector 1 or 512B on eMMC and then MicroSD.
- If the bootloader is not found and the USB dual role port is connected to a computer, it will go into ROM mode. If the USB dual role port is not connected to a computer, it will go to step 3 again.
- If a bootloader is found, it loads the bootloader which will initialize the DRAM and then run u-boot.
- u-boot will turn on the green LED to indicate that the system has software running.
