**************************
Freescale i.MX28 EVK board
**************************
This file documents the Buildroot support for the Freescale i.MX28 EVK board.
Read the i.MX28 Evaluation Kit Quick Start Guide [1] for an introduction to the
board.
Build
=====
First, configure Buildroot for your i.MX28 EVK board:
make freescale_imx28evk_defconfig
Build all components:
make
You will find in ./output/images/ the following files:
- imx28-evk.dtb
- rootfs.tar
- u-boot.sd
- 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
Run the following script as root on your SD card. This will partition the card
and copy the bootloader, kernel and root filesystem as needed.
*** WARNING! The script will destroy all the card content. Use with care! ***
./board/freescale/imx28evk/create-boot-sd.sh <your-sd-device>
Boot the i.MX28 EVK board
=========================
To boot your newly created system (refer to the i.MX28 EVK Quick Start Guide
[1] for guidance):
- insert the SD card in the SD Card Socket 0 of the board;
- verify that your i.MX28 EVK board jumpers and switches are set as mentioned
in the i.MX28 EVK Quick Start Guide [1];
- connect an RS232 UART cable to the Debug UART Port and connect using a
terminal emulator at 115200 bps, 8n1;
- power on the board.
Enjoy!
