Introduce imx6-sabreauto_defconfig that uses mainline U-Boot and mainline kernel. As mainline U-Boot supports SPL, it is possible to boot the same sdcard.img in the three mx6sabreauto variants: imx6q, imx6dl and imx6qp. Also update the readme.txt file to explain how to build an image for mx6sabreauto boards using mainline U-Boot and kernel.

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
|

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.
|
|
|
|
