LEC-iMX6

1.5 Getting Started

This section describes how to configure the boot select jumpers on the LEC-BASE baseboard

and how to configure U-Boot to run a Linux image.

1.5.1 Configure boot select jumpers

Before starting up the LEC-iMX6, the boot select jumpers on the LEC-BASE baseboard must be

configured to correspond with the storage location of the U-Boot boot loader. This section also

discusses boot requirements for the Operating System.

Before you boot your system, consider the storage locations of the following software:

 U-Boot boot loader

 Linux Operating System

The storage locations (devices) of these two software packages can be the same or distinct.

1. To boot the system from a specific boot device (location of the U-Boot boot loader), the

LEC-BASE boot select jumpers must be set as shown in the following photos.

2. The storage location of the Operating System can be set during boot up through a

U-Boot command entry. Otherwise, the default setting will be used.

Boot from module eMMC

(JP16=2-3; JP17=1-2; JP18 1-2; JP19=1-2)

Boot from module SPI flash

(JP16=1-2; JP17=1-2; JP18 1-2; JP19=1-2)

Boot from carrier SATA disk

(JP16=2-3; JP17=2-3; JP18 2-3; JP19=1-2)

Boot from carrier SD card

(JP16=1-2; JP17=2-3; JP18 2-3; JP19=1-2)
