Building for AM335x with meta-ti and meta-qt5

Building for AM335x with meta-ti and meta-qt5

[Andy Pont]

[-- Attachment #1: Type: text/plain, Size: 1661 bytes --]

I am trying to build a Yocto (warrior) image for the AM335x using 
meta-ti and meta-qt5 that will render directly to the GPU.  Initially 
this will be for the Beaglebone Black but then ultimately will be for a 
custom hardware platform.

In broad outline, I think, the software stack needs to look a bit like:

Qt Application
QtBase, QtWebEngine, etc.
Qt-OpenGL
ti-sgx-ddk
AM335x GPU

I have included meta-ti and meta-qt5 into my belayers.conf and added 
ti-sgx-ddk-km, ti-sgx-ddk-um, qtbase and qtwebengine to 
IMAGE_INSTALL_append.  When I try to bitbake core-image-minimal I start 
to get a failure to compile ti-sgx-ddk-km with a number of, what appear 
to be, warnings of the form:

KBUILD_EXTRA_SYMBOLS=
| grep: 
/home/me/Yocto/BeagleBoneBlack/tmp/work-shared/beaglebone/kernel-source/include/linux/amba: 
Is a directory
| grep: 
/home/me/Yocto/BeagleBoneBlack/tmp/work-shared/beaglebone/kernel-source/include/linux/avf: 
Is a directory

It then ultimately appears to give up with:

| ******* Multiarch build: no
| ******* Primary arch:    target_armel
| ******* Secondary arch:  none
| ../config/core.mk:513: $(KERNELDIR)/vmlinux does not exist. Kbuild may 
fail.
| eurasiacon/build/linux2/toplevel.mk:230: 
eurasiacon/build/linux2/moduledefs/target_armel.mk: No such file or 
directory

Is there a specific kernel I need to define in local.conf that the GPU 
drivers build against?

Also, is there any specific configuration I need to do in order to get 
Qt to use the SGX OpenGL drivers?

I have had a search on the web but not found anything for recent Yocto 
versions, only very old stuff.

-Andy.

What's your DISTRO, your MACHINE, TUNES and any other special configs?

It's been working fine for years, hence no recent discussions. You may want to 
look into TI Processor SDK for AM335x - it's Yocto Project based Arago distro 
that is configured for Qt5-Wayland/Weston-SGX, but has been also tested with 
EGLFS QPA.

For the starters, check this out! Not really what you want, but maybe
good starting point.

TI develops it's SDK based on Yocto here
http://arago-project.org/wiki/index.php/Main_Page

The latest master I'm able to use is Thud release.

HTH,

DISTRO is set to “poky” and machine is set to “beaglebone”. I’m not 
aware of a TUNES option.

I’ll take a look at that and see if it makes for a better solution.

This gets pulled from 
https://git.ti.com/graphics/omap5-sgx-ddk-linux/commits/ti-img-sgx/1.17.4948957/k4.19 
and the files in the …/eurasiacon/build/linux2/moduledefs/ directory 
are:

host_i386.mk
target_aarch64.mk
target_i686.mk
target_neutral.mk
host_x86_64.mk
target_armhf.mk
target_mips32r2el.mk
target_x86_64.mk

I’m guessing it is supposed to be using target_armhf.mk but I can’t 
figure out why it is making the incorrect decision and trying to use a 
file that doesn’t exist.
