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.

S2 boot switches

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
