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

​

This file documents the Buildroot support for Engicam i.CoreM6 RQS

SOM platform boards.

​

i.CoreM6 Quad/Dual/DualLite/Solo RQS SOM Starter kits:

https://www.engicam.com/vis-prod/101124

​

This configuration uses U-Boot mainline and kernel mainline.

​

Build

=====

​

First, configure Buildroot for the Engicam i.CoreM6 RQS:

​

- for i.CoreM6 RQS Quad/Dual/DualLite/Solo:

​

  make engicam_imx6qdl_icore_rqs_defconfig

​

Build all components:

​

  make

​

You will find the following files in output/images/:

- for i.CoreM6 Quad/Dual RQS:

  - imx6q-icore-rqs.dtb

- for i.CoreM6 DualLite/Solo RQS:

  - imx6dl-icore-rqs.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/icorem6_rqs/genimage.cfg

​

Boot the i.CoreM6 RQS 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 J7 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 JM2 for sd boot.

- power on the board.

​

Enjoy!
