From 27a2cd6a1980adf3002412678c8fdec6528dc47d Mon Sep 17 00:00:00 2001

Subject: [PATCH] imx: Create distinct pre-processed mkimage config files
Each imx image is created by a separate sub-make and during this process
the mkimage config file is run though cpp.
The cpp output is to the same file no matter what imx image is being
created.
This means if two imx images are generated in parallel they will attempt
to independently produce the same pre-processed mkimage config file at
the same time.
Avoid the problem by making the pre-processed config file name unique
based on the imx image it will be used in. This way each image will
create a unique config file and they won't clobber each other when run
in parallel.
This should fixed the build bug referenced in b5b0e4e3 ("imximage:
Remove failure when no IVT offset is found").

Subject: [PATCH] mx6qsabre_common: boot Linux to /init in mfgtools mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Buildroot supplies a nice /init wrapper script to use when booting from a
ramdisk.
This patch tells u-boot to tell the kernel to boot into /init (instead of
/linuxrc) on i.MX6, when booting in mfgtools mode. This way we can boot a
buildroot system entirely through USB.

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:
http://cache.freescale.com/files/32bit/doc/quick_start_guide/SABRESDB_IMX6_QSG.pdf
Read the i.MX 6 SoloX SABRESD Quick Start Guide for an introduction to
the board:

Read the SABRE for Automotive Infotainment Quick Start Guide for an
introduction to the board:
http://cache.freescale.com/files/32bit/doc/user_guide/IMX6SABREINFOQSG.pdf
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!
