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 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!
