TBD: sostituire le opzioni di boot con quelle disponibili nel SOC e nella Carrier
Boot Configurations[edit | edit source]
ETRA Evaluation Board is built upon TBD:SOC processor.
The following sections detail boot configuration options, which differ depending on the SoM.
Available options[edit | 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.
| 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 |
