# 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!
