**************************

This file documents the Buildroot support for the Freescale i.MX51 EVK board.
|
||
|
|
|
||
|
|
Build
|
||
|
|
=====
|
||
|
|
|
||
|
|
First, configure Buildroot for the i.MX51 EVK board:
|
||
|
|
|
||
|
|
make mx51evk_defconfig
|
||
|
|
|
||
|
|
Build all components:
|
||
|
|
|
||
|
|
make
|
||
|
|
|
||
|
|
You will find in output/images/ the following files:
|
||
|
|
- imx51-babbage.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/imx51evk/genimage.cfg.
|
||
|
|
|
||
|
|
Boot the i.MX51 EVK board
|
||
|
|
=========================
|
||
|
|
|
||
|
|
To boot your newly created system:
|
||
|
|
- insert the SD card in the SD slot of the board;
|
||
|
|
- 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!
