Buildroot for Engicam Is.IoT SOM platforms:
********************************************
This file documents the Buildroot support for all Engicam Is.IoT MX6UL
SOM platform boards.
Is.IoT MX6UL SOM Starter kits:
https://www.engicam.com/vis-prod/101122
This configuration uses U-Boot mainline and kernel mainline.
Build
=====
First, configure Buildroot for the Engicam Is.IoT MX6UL SOM:
- for Is.IoT MX6UL SOM:
make engicam_imx6ul_isiot_defconfig
Build all components:
make
You will find the following files in output/images/:
- imx6ul-isiot-emmc.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/isiot/genimage.cfg
Boot the Is.IoT MX6UL 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!
