This file documents the Buildroot support for the Freescale SABRE Board for
|
|
Smart Devices Based on the i.MX 6 Series (SABRESD).
|
|
|
|
Read the SABRESD Quick Start Guide for an introduction to the board:

Build
|
|
=====
|
|
|
|
First, configure Buildroot for your SABRESD board.
|
|
For i.MX6Q:
|
|
|
|
make freescale_imx6qsabresd_defconfig
|
|
|
|
For i.MX6DL:
|
|
|
|
make freescale_imx6dlsabresd_defconfig
|
|
|
|
Build all components:
|
|
|
|
make
|
|
|
|
You will find in ./output/images/ the following files:
|
|
- imx6dl-sabresd.dtb or imx6q-sabresd.dtb
|
|
- rootfs.ext2
|
|
- rootfs.tar
|
|
- u-boot.imx
|
|
- uImage
|
|
|
|
Create a bootable SD card
|
|
=========================
|
|
|
|
To determine the device associated to the SD card have a look in the
|
|
/proc/partitions file:
|
|
|
|
cat /proc/partitions
|
|
|
|
Run the following script as root on your SD card. This will partition the card
|
|
and copy the bootloader, kernel, DTBs and root filesystem as needed.
|
|
|
|
*** WARNING! The script will destroy all the card content. Use with care! ***
|
|
|
|
./board/freescale/imx6sabresd/create-boot-sd.sh <your-sd-device>
|
|
|
|
Boot the SABRESD board
|
|
======================
|
|
|
|
To boot your newly created system (refer to the SABRESD Quick Start Guide for
|
|
guidance):
|
|
- insert the SD card in the SD3 slot of the board;
|
|
- locate the BOOT dip switches (SW6), set dips 2 and 7 to ON, all others to OFF;
|
|
- connect a Micro USB cable to Debug Port and connect using a terminal emulator
|
|
at 115200 bps, 8n1;
|
|
- power on the board.
|
|
|
|
Enjoy!
