Step by step Qtouch screen with CC6UL pro

0 votes
Reaching out for help,
I got a ConnectCore 6UL SBC Pro with an 7" LCD Accessory Kit, and tried to follow the 'Getting started' and got the first examples running (hello world, and gpio)
But know i need to have the lcd kit working, LCD and Qtouch. I know I have to change the device tree to configure it (as explained here https://www.digi.com/resources/documentation/digidocs/90002285/Default.htm#task/t_enable_fusion_display.htm%3FTocPath%3DFAQ%7C_____4), but I dont know how or where to do this.

I am completly new with this device, total noob with linux, so any help will be really appreciated

Best answer
do you have a Fusion display?
device tree files are documented here:
https://www.digi.com/resources/documentation/digidocs/embedded/dey/dey-2.4/cc6ul/yocto-bsp_r_device-tree-files

if you are using the LCD I've mentioned above the changes to the device tree are documented here:
https://www.digi.com/resources/documentation/digidocs/90002285/#task/t_enable_fusion_display.htm

device tree files should be ./your_workspase_project/tmp/work-shared/ccimx6ulsbc/kernel-source/arch/arm/boot/dts/
Here is what I do to change device tree and re-compile:
source dey-setup-environment
bitbake -c devshell virtual/kernel
---this will start a development shell
vi arch/arm/boot/dts//imx6qp-ccimx6qpsbc.dtsi
exit
----This will exit the development shell
Above is optional as you can simply edit files directly in ./your_workspase_project/tmp/work-shared/ccimx6ulsbc/kernel-source/arch/arm/boot/dts/
bitbake -c compile -f u-boot-dey
bitbake -c compile -f linux-dey
bitbake -c deploy linux-dey
bitbake dey-image-qt
