TBD: sostituire le opzioni di boot con quelle disponibili nel SOC e nella Carrier
Boot ConfigurationsEdit
AXEL Lite Evaluation Board is built upon TBD:SOC processor.
The following sections detail boot configuration options, which differ depending on the SoM.
Available optionsEdit
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 |
