====== MBa7x DIP switch settings ======
===== Boot Device Selection (S1, S2, S3 & S4) =====
To select the desired boot medium set the DIP switches S2, S3, S4 and S1 accordingly.

<WRAP round important 60%>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. </WRAP>

To enable boot device selection BOOT_MODE has to be set to "Internal Boot".\\ This can be done using DIP switch 
S1 on MBa7x:

^<panel type="default" title="Boot Modes">
^ BOOT_MODE         ^  S1-1  ^  S1-2  ^
| Boot from eFuses  |  0   |  0   |
| Serial Downloader |  0   |  1   |
| Internal Boot     |  1   |  0   |
</panel>



The following boot modes of the i.MX7 can be selected by the DIP switches S1, S2, S3 and S4 on the MBa7x.
