+***************************
+Freescale i.MX6ULL EVK board
+***************************
+
+This file documents the Buildroot support for the Freescale i.MX6ULL EVK board.
+
+Please read the i.MX6ULL Evaluation Kit Quick Start Guide [1] for an
+introduction to the board.
+
+Build
+=====
+
+First, configure Buildroot for your i.MX6ULL EVK board:
+
+make imx6ullevk_defconfig
+
+Build all components:
+
+  make
+
+You will find in ./output/images/ the following files:
+  - imx6ull-14x14-evk.dtb
+  - rootfs.ext4
+  - rootfs.tar
+  - sdcard.img
+  - u-boot.imx
+  - zImage
+
+Create a bootable microSD card
+==============================
+
+To determine the device associated to the microSD 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! 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.MX6ULL EVK board
+=========================
+
+To boot your newly created system (refer to the i.MX6ULL EVK Quick Start Guide
+[1] for guidance):
+- insert the microSD card in the microSD slot of the board;
+- verify that your i.MX6ULL EVK board jumpers and switches are set as mentioned
+  in the i.MX6ULL EVK Quick Start Guide [1];
+- put a micro USB cable into the Debug USB Port and connect using a terminal
+  emulator at 115200 bps, 8n1;
+- power on the board.
+
+Enjoy!

Thanks for your contribution.
I have tried and built this new defconfig and I do get the correct
artifiacts mentioned in your description.
I couldn't test it though as I don't have the board.

Two comments:
1)  the subject of your commit should say: configs/imx6ullevk: new defconfig
Then you can add more information in your commit message

2) You need to add an entry to the DEVELOPERS file with your name and
contribution if you want to be the maintainer of this board.

Can you please send a v2 version?

Thanks
Gilles.

[Buildroot] [PATCH 1/1] configs/imx6ullevk: add imx6ullevk support

[Thomas Petazzoni]

Hello Jeffrey,

Thanks for your contribution, and sorry for the slow feedback. Gilles
already commented that the DEVELOPERS file needs to be updated. But
there is another issue that I can't fix myself. See below.

This option does not exist when BR2_TARGET_UBOOT_BUILD_SYSTEM_KCONFIG=y.

But more importantly, we need to have a specific U-Boot version
selected, not just what happens to be the default. Indeed, just like
for the Linux kernel, we want to be sure to rebuild always the same
U-Boot version.

Could you adjust this, and send an updated version ?

Thanks!

[Buildroot] [PATCH v2] configs/imx6ullevk: new defconfig board/freescale/imx6ullevk/readme.txt: new readme for the imx6ullevk board. DEVELOPERS: Add myself as the maintainer of imx6ullevk.

[Jeffrey Kinross]

Changes v1 -> v2:
 - DEVELOPERS - Add myself as maintainer of configs/imx6ullevk (suggested by Gilles Talis)
 - configs/imx6ullevk - Use the FSL kernel and uboot. Pin the kernel and uboot version (suggested by Thomas Petazzoni)

configs/imx6ullevk: new defconfig
board/freescale/imx6ullevk/readme.txt: new readme for the imx6ullevk board.
DEVELOPERS: Add myself as the maintainer of imx6ullevk.

Add support for imx6ullevk board, using the kernel and uboot from the FSL Community BSP.

Thanks a lot for your contribution. However in the mean time, we have
merged
https://git.buildroot.org/buildroot/tree/configs/freescale_imx6ullevk_defconfig
which supports the same board, also with the NXP-provided kernel and
U-Boot.

Best regards,

Thomas Petazzoni
