MBa7x DIP switch settings

To select the desired boot medium set the DIP switches S2, S3, S4 and S1 accordingly.

Switching boot sources is only possible if the BOOT_MODE fuses are not programmed. If configured for “Boot from eFuses” but fuses are not programmed, the boot loader will not be able to determine the boot source.

To enable boot device selection BOOT_MODE has to be set to “Internal Boot”.
This can be done using DIP switch S5 on MBa6x:

BOOT_MODE S1-1 S1-2
Boot from eFuses 0 0
Serial Downloader 0 1
Internal Boot 1 0

The following boot modes of the i.MX6 can be selected by the DIP switches S1, S2, S4 and S5 on the MBa6x.

S2 S3 S4 S1
DIP 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 1 2 3 4 1 2
