Boot Configurations[edit | edit source]
ETRA Evaluation Board is built upon STM32MP1 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 S1 DIP-switch which acts directly on BOOT_MODE[2..0] configuration pins.
S1 switches are connected to ETRA BOOT_MODE[2:0] pins allowing different boot modes.
where S1 switches are mapped as the following table:
| BOOT_MODE | S1 | Note |
|---|---|---|
| BOOT_MODE0 | S1.1 | |
| BOOT_MODE1 | S1.2 | |
| BOOT_MODE2 | S1.3 | |
| - | S1.4 | USB OTG settings |
DIP settings[edit | edit source]
| BOOT_MODE[2:0] | S1[3..1] | Boot peripheral | Notes |
|---|---|---|---|
| 000 | OFF-OFF-OFF | USB | boot from USB OTG |
| 001 | OFF-OFF-ON | NOR | boot from NOR flash on Quad-SPI |
| 010 | OFF-ON-OFF | eMMC | boot from eMMC on SDMMC2 |
| 101 | ON-OFF-ON | SD | Default boot from SD card on SDMMC1 |
| 111 | ON-ON-ON | NAND | boot from NAND flash on Quad-SPI |
