MBa6ULx DIP switch settings

Boot Mode (S5)

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 MBa6ULx:

MBa6ULx Rev.01xx

MBa6ULx Rev.0200

BOOT_MODE S5-1 S5-2
Boot from eFuses 0 0
Internal Boot 0 1
Serial Downloader 1 0
Reserved 1 1



Boot Devices (S11, S12)

The i.MX6ULx can boot from the following boot devices, which can be selected by the DIP switches S11, S12 and S13.

MBa6ULx Rev.01xx
