Freescale i.MX7D SDB board
***************************
This file documents the Buildroot support for the Freescale i.MX7D SDB board.
Build
=====
First, configure Buildroot for your i.MX7D SDB board:
make freescale_imx7dsabresd_defconfig
Build all components:
make
You will find in output/images/ the following files:
- imx7d-sdb.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/imx7dsdb/genimage.cfg.
Boot the i.MX7D SDB 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!
