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

This file documents the Buildroot support for all Engicam GEAM6UL
|
SOM platform boards.
|
|
GEAM6UL SOM Starter kits:
|
https://www.engicam.com/vis-prod/101115
|
|
This configuration uses U-Boot mainline and kernel mainline.
|
|
Build
|
=====
|
|
First, configure Buildroot for the Engicam GEAM6UL SOM:
|
|
- for GEAM6UL SOM:
|
|
make engicam_imx6ul_geam_defconfig
|
|
Build all components:
|
|
make
|
|
You will find the following files in output/images/:
|
- imx6ul-geam-kit.dtb
|
- rootfs.ext4
|
- rootfs.tar
|
- sdcard.img
|
- SPL
|
- u-boot-dtb.img
|
- uImage
|
|
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>
|
sync
|
|
*** WARNING! This will destroy all the card content. Use with care! ***
|
|
For details about the medium image layout, see the definition in
|
board/engicam/geam6ul/genimage.cfg
|
|
Boot the GEAM6UL boards with SD boot:
|
====================================
|
|
To boot your newly created system:
|
- insert the SD card in the SD slot of the board;
|
- connect 3-wire RS232 serial port J28 on board, and connect with other
|
serial end or USB cable(if serial-to-usb converter used) using
|
a terminal emulator at 115200 bps, 8n1;
|
- close JM3 for sd boot.
|
- power on the board.
|
|
Enjoy!
