[yocto] Beaglebone Black - LCD 7''

[Martin Beaudet]

Hi,

I build a Beaglebone Black image using Yocto with this configuration : 

	BB_VERSION        = "1.22.0"
	BUILD_SYS         = "x86_64-linux"
	NATIVELSBSTRING   = "Ubuntu-14.10"
	TARGET_SYS        = "arm-poky-linux-gnueabi"
	MACHINE           = "beaglebone"
	DISTRO            = "poky"
	DISTRO_VERSION    = "1.6.2"
	TUNE_FEATURES     = "armv7a vfp thumb neon callconvention-hard cortexa8"
	TARGET_FPU        = "vfp-neon"
	meta
	meta-yocto        = "daisy:02e603e48c6e0b0492f596890adadf6590fa692c"
	meta-oe           = "daisy:d3d14d3fcca7fcde362cf0b31411dc4eea6d20aa"
	meta-ti           = "daisy:3a95559c124d3ce8c076b3fae5859435977d1ac2"
	meta-qt5          = "master:87235825459d376bf4537c9523eb2496e15893aa"

The on HDMI works very well. I have force a better resolution for my 24'' monitor by doing :

	#uEnv.txt
	optargs=video=HDMI-A-1:1280x720 at 60

Now I'm trying to get an LCD 7'' working but without success. Even if I have tried many options in the uEnv.txt.

Now someone point me to try this DTS file : https://github.com/RobertCNelson/dtb-rebuilder/blob/3.14-ti/src/arm/am335x-bone-4dcape-70t.dtsi and use the DTB builder.

I did not try yet, hope it will work, but is there a way to automate this process in Yocto ?

Best regards,
