 The i.MX8M Evaluation Kit provides two switches in order to set the boot configurations according to your needs. You can see both switches on the following picture:

-**Boot From Fuses.
+**Boot From Fuses: The i.MX8M Applications Processor can be the set as a boot configuration. This can be made established via eFUSE, a dynamic real-time reprogramming technology of computer chips.
-**Serial Downloader.
+**Serial Downloader: The i.MX8M downloads a program image from a USB connection.
-**Internal Boot (Development).
+**Internal Boot: For development.
 **Reserved.
-The i.MX8M Applications Processor can be the boot configuration selected on '''SW802''' or by the boot configuration stored on internal eFUSE. Alternatively, the i.MX8M can download a program image from a USB connection when configured in serial downloader mode. The method used to determine where the processor finds its boot information is from two dedicated BOOT MODE pins.

-The two pins are tied to the BOOT modules. It is recommended to use the dual-switch ('''SW802''') to select the input voltage of these two
+For example, if the method of determining the bootable source code is selected to be from the switch, then the developer must set the '''SW802:''' PIN1 to ON, PIN2 to OFF, and the four i.MX8M pins of the '''SW801''' must be set on the EVK board by considering the information present in the following table:
-pins, 0 or 3.3 V. If the developer wants to boot the program Image from the Fuses Mode, the position of the switch 1 and 2 must be set to OFF, it is the same principle to choose the Serial Downloader Module or Internal Boot Module to load bootable code into the processor.
-If the method of determining the bootable source code is selected to be from the hardware, then the developer must set the switch '''SW802:''' MODE0 to OFF, MODE1 to ON, and the four i.MX8M pins of the '''SW801''' must be set on the EVK board by considering the information present in the following table:
