-============
-
-Vyasa is RK3288 based Single board computer with fully supported opensource software.
-
-https://openedev.amarulasolutions.com/display/ODWIKI/Vyasa+RK3288
-
-How to build it
-===============
-
-  $ make amarula_vyasa_rk3288_defconfig
-
-Then you can edit the build options using
-
-  $ make menuconfig
-
-Compile all and build rootfs image:
-
-  $ make
-
-Prepare your SDCard
-===================
-
-Buildroot generates a ready-to-use SD card image that you can flash directly to
-the card. The image will be in output/images/sdcard.img.
-You can write this image directly to an SD card device (i.e. /dev/xxx):
-
-  $ sudo dd if=output/images/sdcard.img of=/dev/xxx
-  $ sudo sync
-
-Finally, you can insert the SD card to the Vyasa RK3288 board, close J4 and boot it.

-Arcturus uCLS1012A SoM
-======================
-
-This tutorial describes how to use the predefined Buildroot
-configuration for the Arcturus uCLS101A SoM platform.
-
-Additional information about the uCLS1012A System on Module can be found at
-https://www.arcturusnetworks.com/products/ucls1012a
-and product support for registered users at
-https://www.arcturusnetworks.com/support
-
-Building
--------
-
-Return to the top directory <buildrootdir> and execute the following commands.
-
-  make arcturus_ucls1012a_defconfig
-  make
-
-Result of the build
-------------------
-
-After building, you should obtain this tree:
-
-    output/images/
-    +-- arc-ucls1012a.dtb
-    +-- Image
-    +-- part0-000000.itb
-    +-- rootfs.cpio
-    +-- rootfs.cpio.gz
-    +-- rootfs.tar
-    +-- u-boot.bin
-    +-- ucls1012a.its
-
-Flashing
--------
-
-You'll need to program the image created by buildroot into the SPI NOR flash.
-
-1. Reboot your module and via the serial console press <escape> to enter the B$
-u-boot shell.
-   From the shell you will need to update four environment variables replacing the
-   IPv4 IP Address with ones that will work with your network and tftp server.
-
-   B$ setenv ipaddr 192.168.1.81
-   B$ setenv serverip 192.168.1.80
-   B$ setenv gatewayip 192.168.1.1
-   B$ setenv netmask 255.255.255.0
-   B$ saveenv
-
-2. Enable tftp server to serve the <buildrootdir>/output/images/ folder.
-
-3. Program the new U-Boot binary (optional)
-    If you don't feel confident upgrading your bootloader then don't do it,
-    it's unnecessary most of the time.
-
-    B$ tftp u-boot.bin
-    B$ run program_uboot
-
-4. Program the ITB image (includes Kernel, DTB and Ramdisk)
-
-    B$ tftp part0-000000.itb
-    B$ run iprogram
-
-5. Booting your new system
-
-    Reboot your system by reset command
-    B$ reset
-
-        or
-
-    B$ run bootcmd
-
-Good Luck !

-Tinker RK3288
-=============
-
-Tinker Board is a Single Board Computer (SBC) in an ultra-small form
-factor that offers class-leading performance while leveraging outstanding
-mechanical compatibility.
-
-Tinker link:
-https://www.asus.com/in/Single-Board-Computer/Tinker-Board/
-
-Wiki link:
-https://openedev.amarulasolutions.com/display/ODWIKI/Tinker+RK3288
-
-How to build it
-===============
-
-  $ make asus_tinker_rk3288_defconfig
-
-Then you can edit the build options using
-
-  $ make menuconfig
-
-Compile all and build rootfs image:
-
-  $ make
-
-Prepare your SDCard
-===================
-
-Buildroot generates a ready-to-use SD card image that you can flash directly to
-the card. The image will be in output/images/sdcard.img.
-You can write this image directly to an SD card device (i.e. /dev/xxx):
-
-  $ sudo dd if=output/images/sdcard.img of=/dev/xxx
-  $ sudo sync
-
-Finally, you can insert the SD card to the Tinker RK3288 board and boot it.

 * MIPS Creator CI20 *
 *********************

-Introduction
-============
-
 The 'ci20_defconfig' will create a root filesystem and a kernel image
 under the 'output/images/' directory. This document will try to explain how
 to use them in order to run Buildroot in the MIPS Creator CI20 board.

-How to build it
-===============
+Assuming you are at the U-Boot prompt of the MIPS Creator CI20, you have to
+load the generated kernel image by using the 'tftpboot' command. In
+order to do that, you will need to get the network working. Here you
+have the instructions to set the ip address, netmask and gateway:

-Configure Buildroot
-------------------
+  setenv ipaddr x.x.x.x
+  setenv netmask x.x.x.x
+  setenv gatewayip x.x.x.x

-  $ make ci20_defconfig
+Now you have to set the ip for the TFTP server you are going to load the
+kernel image from, and also the name of the kernel image file (we use
+'uImage' as a filename in this example):

-Build the rootfs
----------------
+  setenv serverip x.x.x.x
+  setenv bootfile uImage

-Note: you will need to have access to the network, since Buildroot will
-download the packages' sources.
+And finally load the kernel image:

-You may now build your rootfs with:
+  tftpboot

-  $ make
+Now you have to extract the generated root filesystem into a USB drive
+or SD-Card. Here you have the instructions to boot from the two of them.
+You have to choose the one your prefer:

-(This may take a while, consider getting yourself a coffee ;-) )
+From USB
+  setenv bootargs console=ttyS4,115200 console=tty0 mem=256M@0x0
+mem=768M@0x30000000 root=/dev/sda1

-How to write the SD card
-========================
+From SD-Card
+  setenv bootargs console=ttyS4,115200 console=tty0 mem=256M@0x0
+mem=768M@0x30000000 root=/dev/mmcblk0p1

-Once the build process is finished you will have an image called
-"sdcard.img" in the output/images/ directory.
-
-Make sure the SD card is not mounted then copy the bootable "sdcard.img" onto
-it with "dd":
-
-  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
-
-Insert the SDcard into your ci20, and power it up. Your new system
-should come up now and start a console on the UART HEADER.
-
-see: https://elinux.org/CI20_Hardware#Dedicated_UART_header
+And finally run this command to boot the board:
+  bootm

+* MIPS Creator CI40 *
+*********************
+
+This document details how to build and run a Buildroot system on the
+MIPS Creator CI40 platform. For more details about the CI40, see
+https://creatordev.io/ci40-iot-hub.html.
+
+How to build
+------------
+
+$ make ci40_defconfig
+$ make
+
+Prepare USB/MMC for boot
+------------------------
+
+On successful build, "sdcard.img" file will be created in 'output/images'
+folder.
+
+Use following command to write image to bootable device
+
+$ sudo dd if=./output/images/sdcard.img of=/dev/<your-microsd-or-usb-device>
+
+Booting from USB/MMC
+--------------------
+
+The boot loader is already present in NOR flash. To boot your newly generated
+Linux and root filesystem, you need to interrupt U-Boot autoboot. Current
+U-Boot is configured with 2 seconds of boot-delay, after expiry of this
+boot-delay timeout U-Boot starts booting the default image. To interrupt
+autoboot, press any key before the boot-delay time expires, U-Boot will
+stop the autoboot process and give a U-Boot prompt. You can now boot to
+your preferred boot method as describe below:
+
+From USB
+  pistachio # run usbboot
+
+From SD-Card
+  pistachio # run mmcboot
+
+Persistent boot command
+-----------------------
+
+To boot automatically to your preferred boot method, use following command to
+make it persistent, for example to automatically boot to usb:
+
+  pistachio # setenv bootcmd run usbboot
+  pistachio # saveenv
+
+Flash new bootloader
+--------------------
+
+The bootloader image will be available in the 'output/images' folder. To flash
+the new bootloader, copy it to the device and use the following command on the
+device:
+
+# flashcp -v u-boot-pistachio_marduk-<version>.img /dev/mtd0

+Buildroot for Embest RIoTboard
+==============================
+
+1. Compiling buildroot
+----------------------
+
+make riotboard_defconfig
+make
+
+2. Installing buildroot
+-----------------------
+
+Prepare an SD-card and plug it into your card reader. Write the bootloader to
+your SD-card:
+
+sudo dd if=output/images/u-boot.imx of=/dev/sdX bs=1k seek=1
+
+Create 1 partition on the SD-card using your favourite tool. The
+partition should be big enough to hold your rootfs, for example
+128MiB. Here's an example partition layout:
+
+   Device Boot      Start         End      Blocks   Id  System
+/dev/sdX1            2048      264191      131072   83  Linux
+
+Format the SD-card partition with your favourite filesystem:
+
+sudo mkfs.ext2 /dev/sdX1
+
+Deploy your rootfs to the SD-card:
+
+sudo mkdir /mnt/sdcard/
+sudo mount /dev/sdX1 /mnt/sdcard/
+sudo tar xf output/images/rootfs.tar -C /mnt/sdcard/
+sudo umount /dev/sdX1
+
+3. Running buildroot
+--------------------
+
+Position the board so you can read the label "RIoTboard" on the right side of
+SW1 DIP switches. Configure the SW1 swiches like this:
+
+10100101 (1 means ON position, 0 means OFF position)
+
+Now plug your prepared SD-card in slot J6. Connect a serial console (115200, 8,
+N, 1) to header J18. Connect a 5V/1A power supply to the board and enjoy your
+new toy.

+**************************************
+Freescale i.MX31 PDK development board
+**************************************
+
+This file documents the Buildroot support for the Freescale i.MX31 PDK in "3
+stack" configuration.
+
+The i.MX31 Product Development Kit (or PDK) is Freescale development board [1]
+based on the i.MX31 application processor [2].
+
+For more details on the i.MX31 PDK board, refer to the User's Guide [3].
+
+Build
+=====
+
+First, configure Buildroot for your i.MX31 PDK board:
+
+  make freescale_imx31_3stack_defconfig
+
+Build all components:
+
+  make
+
+You will find in ./output/images/ the following files:
+  - rootfs.cpio
+  - rootfs.cpio.gz
+  - rootfs.tar
+  - zImage
+
+The generated zImage does include the rootfs.
+
+Boot the PDK board
+==================
+
+The i.MX31 PDK contains a RedBoot bootloader in flash, which can be used to
+boot the newly created Buildroot images from the network.
+
+This necessitates to setup a TFTP server first. This setup is explained for
+example in Freescale i.MX31 PDK 1.5 Linux User's Guide [4].
+
+Here is a sample RedBoot configuration, for proper network boot of Buildroot on
+the i.MX31 PDK:
+
+    RedBoot> fconfig -l
+    Run script at boot: true
+    Boot script:
+    .. load -r -b 0x100000 zImage
+    .. exec -c "console=ttymxc0,115200"
+
+    Boot script timeout (1000ms resolution): 2
+    Use BOOTP for network configuration: false
+    Gateway IP address: <your gateway IP address>
+    Local IP address: <your PDK IP address>
+    Local IP address mask: 255.255.255.0
+    Default server IP address: <your TFTP server IP address>
+    Board specifics: 0
+    Console baud rate: 115200
+    Set eth0 network hardware address [MAC]: false
+    GDB connection port: 9000
+    Force console for special debug messages: false
+    Network debug at boot time: false
+
+Adapt those settings to your network configuration by replacing the appropriate
+network addresses where necessary.
+
+You might want to verify that your i.MX31 PDK switches settings are the correct
+ones for UART, power, boot mode, etc. Here is a reference switches
+configuration:
+
+    SW4
+    1   2   3   4   5   6   7  8
+    ON off off off off off off ON
+
+    SW5 SW6 SW7 SW8 SW9 SW10
+     0   1   0   0   0    0
+
+See the i.MX31 PDK Linux Quick Start Guide [5] for more details on the switches
+settings.
+
+Connect a serial terminal set to 115200n8 and power on the i.MX31 PDK board.
+Buildroot will present a login prompt on the serial port.
+
+Enjoy!

-Freescale i.MX6 Sabre SD boards
-*******************************
-
-This file documents the Buildroot support for the Freescale i.MX6 Sabre SD
-boards based on i.MX6Q, i.MX6DL and iMX6QP.
-
-Thanks to the SPL support in U-Boot it is possible to run a single
-sdcard.img in all i.MX6 Sabre SD board variants.
-
-This configuration uses U-Boot mainline and kernel mainline.
-
-Build
-=====
-
-First, configure Buildroot for the i.MX6 Sabre SD board:
-
-  make imx6-sabresd_defconfig
-
-Build all components:
-
-  make
-
-You will find the following files in output/images/ :
-  - imx6q-sabresd.dtb
-  - imx6dl-sabresd.dtb
-  - imx6qp-sabresd.dtb
-  - rootfs.ext4
-  - rootfs.tar
-  - sdcard.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 SD card. Launch the following
-command as root:
-
-  dd if=output/images/sdcard.img of=/dev/<your-sd-device>
-
-*** WARNING! This 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 i.MX6 Sabre SD board
-=============================
-
-To boot your newly created system:
- insert the SD card in the SD3 slot of the board (close to the HDMI connector);
- put a micro USB cable into the Debug USB Port and connect using a terminal
-  emulator at 115200 bps, 8n1;
- power on the board.
-
-Testing graphics on the i.MX6 Sabre SD board
-============================================
-
-The imx6-sabresd_qt5_defconfig allows to quickly test the graphics
-capabilities of i.MX6 using the opensource Etnaviv graphics stack
-and kernel mainline.
-
-In order to build it:
-
-make imx6-sabresd_qt5_defconfig
-make
-
-Then flash the SD card as explained above.
-
-Running kmscube application:
-
-# kmscube
-
-Running Qt5 Cinematic Demo:
-
-# export QT_QPA_EGLFS_KMS_CONFIG=/root/sabresd.json
-# /usr/share/Qt5/CinematicExperience/Qt5_CinematicExperience
-
-Running gl2mark benchmark:
-
-# glmark2-es2-drm
-
-Testing video playback on the i.MX6 Sabre SD board
-==================================================
-
-As the mx6sabresd has two display outputs (LVDS and HDMI), it is necessary to
-know what is the connector that corresponds to the HDMI output.
-
-This information can be found by running:
-
-# modetest
-
-And search for the HDMI connector number. In our case it shows up as 37.
-
-In the mx6sabresd prompt run the following Gstreamer pipeline:
-
-# gst-launch-1.0 filesrc location=/root/trailer_1080p_h264_mp3.avi ! avidemux ! \
-h264parse ! v4l2video1dec capture-io-mode=dmabuf ! kmssink connector-id=37    \
-name=imx-drm sync=0

-Subject: [PATCH] imximage: Remove failure when no IVT offset is found
-
-Sometimes imximage throws the following error:
-
-  CFGS    board/freescale/vf610twr/imximage.cfg.cfgtmp
-  CFGS    board/freescale/vf610twr/imximage.cfg.cfgtmp
-  MKIMAGE u-boot-dtb.imx
-Error: No BOOT_FROM tag in board/freescale/vf610twr/imximage.cfg.cfgtmp
-arch/arm/mach-imx/Makefile:100: recipe for target 'u-boot-dtb.imx' failed
-
-Later on, when running mkimage for the u-boot.imx it will succeed in
-finding the IVT offset.
-
-Looks like some race condition happening during parallel build when
-processing mkimage for u-boot-dtb.imx and u-boot.imx.
-
-A proper fix still needs to be implemented, but as a workaround let's
-remove the error when the IVT offset is not found.
-
-It is useful to have such message, especially during bring-up phase,
-but the build error that it causes is severe, so better avoid the

-
-  cat /proc/partitions
-
-Buildroot prepares a bootable "sdcard.img" image in the output/images/
-directory, ready to be dumped on a SD card. Launch the following

-board/freescale/common/imx/genimage.cfg.template_imx8.
-
-Boot the i.MX8MQ EVK board
-==========================
-
-To boot your newly created system:
- insert the SD card in the SD slot of the board;
- Configure the switches as follows:
-SW801:	ON	ON	OFF	OFF
-SW802:	ON	OFF
- put a micro USB cable into the Debug USB Port and connect using a terminal
-  emulator at 115200 bps, 8n1;
- power on the board.
-
-Enable HDMI output
-==================
-
-To enable HDMI output at boot you must provide the video kernel boot
-argument.  To set the video boot argument from U-Boot run after
-stoping in U-Boot prompt:
-
-setenv mmcargs 'setenv bootargs console=${console} root=${mmcroot} video=HDMI-A-1:1920x1080-32@60'
-saveenv
-reset
-
-Change screen resolution to suit your connected display.

-Intro
-=====
-
-This default configuration will allow you to start experimenting with the
-buildroot environment for the Nanopi A64. With the current configuration
-it will bring-up the board, and allow access through the serial console.
-
-Nanopi A64 link:
-http://nanopi.io/nanopi-a64.html
-
-Wiki link:
-https://openedev.amarulasolutions.com/display/ODWIKI/FriendlyARM+Nanopi+A64
-
-This configuration uses U-Boot mainline and kernel mainline.
-
-How to build
-============
-
-    $ make friendlyarm_nanopi_a64_defconfig
-    $ make
-
-Note: you will need access to the internet to download the required
-sources.
-
-How to write the SD card
-========================
-
-Once the build process is finished you will have an image called "sdcard.img"
-in the output/images/ directory.
-
-Copy the bootable "sdcard.img" onto an SD card with "dd":
-
-  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
-  $ sudo sync
-
-Insert the micro SDcard in your Nanopi A64 and power it up. The console
-is on the serial line, 115200 8N1.
