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

Build
=====
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.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 imx6q-sabreauto.dtb or
imx6dl-sabreauto.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/create-boot-sd.sh <your-sd-device>
Boot the SABRE board
====================
SABRE SD
--------
To boot your newly created system on a SABRE SD Board (refer to the 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.
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!
