Processor Boot Configuration
The first row in

is the default setting. On boot, the processor will look for the
eMMC on the MMC1 port first, followed by the uSD slot on MMC0, USB0 and UART0.
In the event there is no uSD card and the eMMC is empty, UART0 or USB0 could be
used as the board source.
If you have a uSD card from which you need to boot from, hold the boot button down.
On boot, the processor will look for the SPIO0 port first, then uSD on the MMC0 port,
