Boot Configurations[edit | edit source]
ORCA Evaluation Board is built upon i.MX8M Plus SoC.
The following sections detail boot configuration options related to the ORCA SOM.
Available options[edit | edit source]
Boot modes can be selected by S2 switches which acts directly on SYSBOOT configuration pins.
S2 switches are connected to ORCA BOOT_MODE[3:0] pins allowing different boot modes.
where S2 switches are mapped as the following table:
| BOOT_MODE | S2 | Note |
|---|---|---|
| BOOT_MODE0 | S2.1 | |
| BOOT_MODE1 | S2.2 | |
| BOOT_MODE2 | S2.3 | |
| BOOT_MODE3 | unused |
| BOOT_MODE[3:0] | S2[4..1] | Boot sequence | Notes |
|---|---|---|---|
| 0000 | OFF-OFF-OFF-OFF | Boot From Internal Fuses | Please contact sales@dave.eu for more information |
| 0001 | OFF-OFF-OFF-ON | USB Serial Download | |
| 0010 | OFF-OFF-ON-OFF | USDHC3 | eMMC boot only, SD3 8-bit |
| 0011 | OFF-OFF-ON-ON | USDHC2 | SD boot only, SD2 microSD |
| 0100 | OFF-ON-OFF-OFF | NAND | 8-bit single device 256 page |
| 0101 | OFF-ON-OFF-ON | NAND | 8-bit single device 512 page |
