TBD: sostituire le opzioni di boot con quelle disponibili nel SOC e nella Carrier

{{{nome-som}}} Evaluation Board is built upon TBD:SOC processor.

The following sections detail boot configuration options, which differ depending on the SoM.

Boot modes can be selected by S3 switches which acts directly on SYSBOOT configuration pins.

S3 switches are mapped to SYBOOT[3:0] pins allowing different boot modes.

Boot options order code	Jumper mounted	Jumper not mounted
Boot from NAND	SD	NAND
Boot from NOR	SD	NOR

Same example can be found in the following table:

SYBOOT[3:0]	Boot sequence	Notes
0111	MMC0/SPI0/UART0	Default boot from NOR SPI
0011	NAND/NANDI2C/MMC0	boot from NAND
1001	SPI0/MMC0/EMAC1	boot from EMAC if DIVA has no NOR and no NAND on board
