Boot Configurations[edit source]
{{{nome-som}}} Evaluation Board is built upon TBD:SOC processor.
The following sections detail boot configuration options, which differ depending on the SoM.
Available options[edit source]
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.
S3 switch | SYSBOOT pin |
---|---|
S3.1 | SYSBOOT3 |
S3.2 | SYSBOOT2 |
S3.3 | SYSBOOT1 |
S3.4 | SYSBOOT0 |
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 |
