Introduce imx6q-sabresd_qt5_defconfig that supports the opensource Etnaviv graphical stack. This defconfig provides a way to quickly test some graphical applications, such as kmscube, qt5, glmark2. Currently kernel mainline exhibits issues when running cpufreq as ondemand governor on mx6, so add a linux fragment that disables such option for the time being. Signed-off-by: Fabio Estevam <festevam@gmail.com> [Arnout: - Add Fabio to DEVELOPERS - Rename linux config fragment to linux_qt5.fragment - Add comment to linux_qt5.fragment why it is needed - Add explicit CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y to it - Reorder defconfig entries to they match imx6q-sabresd_defconfig - Remove strace and host-uboot-tools, neither seems to be needed - Drop BR2_PACKAGE_QT5BASE_LICENSE_APPROVED, it no longer exists - Replace BR2_TARGET_ROOTFS_EXT2_BLOCKS with BR2_TARGET_ROOTFS_EXT2_SIZE - Regenerate .gitlab-ci.yml] Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>

Freescale i.MX6Q Sabre SD board
|
|
*******************************
|
|
|
|
This file documents the Buildroot support for the Freescale i.MX6Q Sabre SD
|
|
board.
|
|
|
|
This configuration uses U-Boot mainline and kernel mainline.
|
|
|
|
Build
|
|
=====
|
|
|
|
First, configure Buildroot for the i.MX6Q Sabre SD board:
|
|
|
|
make imx6q-sabresd_defconfig
|
|
|
|
Build all components:
|
|
|
|
make
|
|
|
|
You will find the following files in output/images/ :
|
|
- imx6q-sabresd.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/common/imx/genimage.cfg.template.
|
|
|
|
Boot the i.MX6Q Sabre SD board
|
|
==============================
|
|
|
|
To boot your newly created system:
|
|
- insert the SD card in the SD3 slot of the board (close to the HDMI connector);
|
|
- put a micro USB cable into the Debug USB Port and connect using a terminal
|
|
emulator at 115200 bps, 8n1;
|
|
- power on the board.
|
|
|
|
Testing graphics on the i.MX6Q Sabre SD board
|
|
=============================================
|
|
|
|
The imx6q-sabresd_qt5_defconfig allows to quickly test the graphics
|
|
capabilities of i.MX6 using the opensource Etnaviv graphics stack
|
|
and kernel mainline.
|
|
|
|
In order to build it:
|
|
|
|
make imx6q-sabresd_qt5_defconfig
|
|
make
|
|
|
|
Then flash the SD card as explained above.
|
|
|
|
Running kmscube application:
|
|
|
|
# kmscube -D /dev/dri/card1
|
|
|
|
Running Qt5 Cinematic Demo:
|
|
|
|
# export QT_QPA_EGLFS_KMS_CONFIG=/root/sabresd.json
|
|
# /usr/share/Qt5/CinematicExperience/Qt5_CinematicExperience
|
|
|
|
Enjoy!
