Freescale i.MX6 Q, DL and SoloX SABRE development boards
********************************************************
This file documents the Buildroot support for the Freescale SABRE Board
for Smart Devices Based on the i.MX 6 and i.MX 6SoloX Series (SABRESD),
as well as the Freescale SABRE Board for Automotive Infotainment.
Read the i.MX 6 SABRESD Quick Start Guide for an introduction to the
board:

Read the i.MX 6 SoloX SABRESD Quick Start Guide for an introduction to
the board:

Building with NXP kernel and NXP U-Boot
=======================================
First, configure Buildroot for your SABRE board.
For i.MX6Q SABRE SD board:
make freescale_imx6qsabresd_defconfig
For i.MX6DL SABRE SD board:
make freescale_imx6dlsabresd_defconfig
For i.MX6 SoloX SABRE SD board:
make freescale_imx6sxsabresd_defconfig
For i.MX6Q SABRE Auto board:
make freescale_imx6qsabreauto_defconfig
For i.MX6DL SABRE Auto board:
make freescale_imx6dlsabreauto_defconfig
Build all components:
make
You will find in ./output/images/ the following files:
- imx6dl-sabresd.dtb or imx6q-sabresd.dtb or imx6sx-sdb.dtb or
imx6q-sabreauto.dtb or imx6dl-sabreauto.dtb
- rootfs.ext2
- rootfs.tar
- u-boot.imx
- uImage, or zImage for i.MX6 SoloX
Building with mainline kernel and mainline U-Boot
=================================================
Mainline U-Boot uses SPL and can support the three
variants of mx6sabreauto boards: mx6q, mx6dl and mx6qp.
First, configure Buildroot for your mx6sabreauto board
make imx6-sabreauto_defconfig
Build all components:
make
You will find in output/images/ the following files:
- imx6dl-sabresd.dtb, imx6q-sabresd.dtb, imx6q-sabresd.dtb
- rootfs.ext2
- SPL and u-boot.img
- u-boot.imx
- zImage
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
Buildroot prepares a bootable "sdcard.img" image in the output/images/
directory, ready to be dumped on a microSD card. Launch the following
command as root:
dd if=./output/images/sdcard.img of=/dev/<your-microsd-device>
*** WARNING! The script will destroy all the card content. Use with care! ***
For details about the medium image layout, see the definition in
board/freescale/common/imx/genimage.cfg.template.
Boot the SABRE board
====================
i.MX6 SABRE SD
--------------
To boot your newly created system on an i.MX6 SABRE SD Board (refer to
the i.MX6 SABRE SD 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.
i.MX6 SoloX SABRE SD
--------------------
To boot your newly created system on an i.MX6 SoloX SABRE SD Board
(refer to the i.MX6 SoloX SABRE SD Quick Start Guide for guidance):
- insert the SD card in the J4-SD4 socket at the bottom of the board;
- Set the SW10, SW11 and SW12 DIP switches at the top of the board in
their default position, to boot from SD card. Reference configuration:
SW10
1 2 3 4 5 6 7 8
off off off off off off off off
SW11
1 2 3 4 5 6 7 8
off off ON ON ON off off off
SW12
1 2 3 4 5 6 7 8
off ON off off off off off off
- connect a Micro USB cable to the J16 Debug Port at the bottom of the
board. This is a dual UART debug port; connect to the first tty using
a terminal emulator at 115200 bps, 8n1;
- power on the board with the SW1-PWR switch at the top of the board.
SABRE Auto
----------
To boot your newly created system on a SABRE Auto Board (refer to the SABRE for
Automotive Infotainment Quick Start Guide for guidance):
- insert the SD card in the CPU card SD card socket J14;
- Set the S1, S2 and S3 DIP switches and J3 jumper to boot from SD on CPU card.
Reference configuration:
S1
1 2 3 4 5 6 7 8 9 10
off ON off off ON off off off off off
S2
1 2 3 4
off off ON off
S3
1 2 3 4
off off ON ON
J3: 1-2
- connect an RS-232 UART cable to CPU card debug port J18 UART DB9 and
connect using a terminal emulator at 115200 bps, 8n1;
- power on the board.
Enjoy!
