# Minimal SD card image for the Freescale's i.MX25 PDK board
#
# We mimic the .sdcard Freescale's image format for i.MX25:
# * the SD card must have 1 kB free space at the beginning,
# * U-Boot is dumped as is,
# * a FAT partition at offset 8 MB is containing zImage and dtbs,
# * a single root filesystem partition is required (Ext4 in this case).

**************************
Freescale i.MX25 PDK board
**************************
This file documents the Buildroot support for the Freescale i.MX25 PDK board.
Build
=====
First, configure Buildroot for the i.MX25 PDK board:
make mx25pdk_defconfig
Build all components:
make
You will find in output/images/ the following files:
- imx25-pdk.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/imx25pdk/genimage.cfg.
Boot the i.MX25 PDK board
=========================
To boot your newly created system:
- insert the SD card in the SD slot of the board;
- put a USB cable into the Debug USB Port and connect using a terminal
emulator at 115200 bps, 8n1;
- power on the board.
Enjoy!
