This file documents the Buildroot support for Engicam i.CoreM6
|
platform boards.
|
|
i.CoreM6 Quad/Dual/DualLite/Solo SOM Starter kits:
|
https://www.engicam.com/vis-prod/101120
|
i.CoreM6 Quad/Dual/DualLite/Solo Open Frame 10.1 C.TOUCH kits:
|
https://www.engicam.com/vis-prod/101133
|
|
This configuration uses U-Boot mainline and kernel mainline.
|
|
Build
|
=====
|
|
First, configure Buildroot for the Engicam i.CoreM6:
|
|
make engicam_imx6qdl_icore_defconfig
|
|
Build all components:
|
|
make
|
|
You will find the following files in output/images/:
|
- imx6q-icore.dtb (for i.CoreM6 Quad/Dual)
|
- imx6dl-icore.dtb (for i.CoreM6 DualLite/Solo)
|
- imx6q-icore-ofcap10.dtb (for i.CoreM6 Quad/Dual ofcap 10)
|
- imx6q-icore-ofcap12.dtb (for i.CoreM6 Quad/Dual ofcap 12)
|
- 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/genimage.cfg
|
|
Boot the i.CoreM6 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.
|
|
Testing graphics on i.CoreM6:
|
============================
|
|
Build with support for Etnaviv, Qt5 and demo applications:
|
|
make engicam_imx6qdl_icore_qt5_defconfig
|
make
|
|
Running kmscube
|
# kmscube -D /dev/dri/card1
|
|
Running glmark2-es2-drm
|
# glmark2-es2-drm
|
|
Running Qt5 Cinematic Demo:
|
- for i.CoreM6 Starter Kit
|
# export QT_QPA_EGLFS_KMS_CONFIG=/root/imx6qdl-icore.json
|
- for i.CoreM6 ofcap10
|
# export QT_QPA_EGLFS_KMS_CONFIG=/root/imx6qdl-icore-ofcap10.json
|
- for i.CoreM6 ofcap12
|
# export QT_QPA_EGLFS_KMS_CONFIG=/root/imx6qdl-icore-ofcap12.json
|
|
# CinematicExperience-demo
|
|
Enjoy!
