Freescale i.MX6UL EVK board

|
This file documents the Buildroot support for the Freescale i.MX6UL EVK board.
|
|
Please read the i.MX6UL Evaluation Kit Quick Start Guide [1] for an
|
introduction to the board.
|
|
Build
|
=====
|
|
First, configure Buildroot for your i.MX6UL EVK board:
|
|
In order to to do so there are two supported options:
|
|
make freescale_imx6ulevk_defconfig
|
|
if you plan to use NXP provided U-Boot and kernel.
|
|
or
|
|
make imx6ulevk_defconfig
|
|
if you plan to use mainline U-Boot and mainline kernel.
|
|
Build all components:
|
|
make
|
|
You will find in ./output/images/ the following files:
|
- imx6ul-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.MX6UL EVK board
|
=========================
|
|
To boot your newly created system (refer to the i.MX6UL EVK Quick Start Guide
|
[1] for guidance):
|
- insert the microSD card in the microSD slot of the board;
|
- verify that your i.MX6UL EVK board jumpers and switches are set as mentioned
|
in the i.MX6UL 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!
