QT5.1.1 running on BeagleBoneBlack

I finally managed to get QT5.1.1 running on BBB. I could not get the cross compile to work so I resorted to compiling QT natively on the BBB.

My setup is as follows:

I followed this guide: http://tigraphics.blogspot.in/2013/11/4q-2013-linux-graphics-sdk-release.html

My BBB mounts the rootfs via NFS on my desktop using the folder targetNFS.

Kernel: git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git
Branch: ti-linux-3.12.y
Apply SGX-DT-node.patch
Not sure why Robert Nelson’s kernel doesn’t work. Will investigate further.

RootFS: omap-image-builder
debian-7.2-machinekit-armhf

Graphics SDK: Graphics_SDK_5_00_00_01_hardfp
Update Make.rules
Desktop #>make BUILD=release OMAPES=8.x PM_RUNTIME=1 all
Desktop #>sudo make BUILD=release OMAPES=8.x PM_RUNTIME=1 install

QT: git://gitorious.org/qt/qt5.git
Branch: v5.1.1
BBB #>./init-repository
BBB #>make
Takes about 40 hours to build
BBB #>make install
Takes about 2 hours to install

TI SGX patches: https://github.com/prabindh/qt-configs.git
Apply patches from qt5_1.0_Aug13, qt5_1_1_Sept13, ti_eglfs and webgl_5.1.1

BBB #>./configure –prefix /home//targetNFS/usr/local/qt5 –release –make libs –platform linux-arm-gnueabi-ti-g++ -opengl es2 -confirm–license –opensource –ice -no–xcb -no–pcb –make examples –verbose –I /home//targetNFS/usr/include/OGLES2 –L /home//targetNFS/lib/arm-linux-gnueabihf

BBB #>/etc/init.d/335x-demo
Reboot BBB

BBB #>modprobe pvrsrvkm
BBB #>modprobe omaplfb
BBB #>/etc/init.d/rc.pvr start
To run qt applications with –platform eglfs you need the following
BBB #>export QT_PLUGIN_PATH=/usr/local/qt5.1.1/plugins
To enable keyboard input do the following:
BBB #>sudo chmod +r /dev/input/event0
To enable mouse input, do the following:
BBB #>sudo chmod +r /dev/input/event1

Performance looks very good.

I hope this help.

Yeah i was hacking on things last friday.. There's a couple drivers
missing from mainline.

https://github.com/RobertCNelson/linux-dev/tree/am33x-v3.12/patches/sgx

Then i was playing around with building the module inside the kernel..
https://github.com/RobertCNelson/linux-dev/tree/am33x-v3.12/patches/sgx-blob

Didn't get very far before running into lots of missing stuff from the
davnci video driver..

Hi Robert,

It would be good to get this fixed, because I don¹t like working with the
TI kernel. The screen resolution defaults to 640x480-60 so it seems like
EDID is somehow broken. ³Enable firmware EDID² is enabled. BTW, where is
the EDID info retrieved/stored. I¹m trying to set the resolution with
fbset using the modes in fb.mode and nothing works except 640x480-60.

John

Hi John,

It's even worse then that.. It's built on top of the old (none kms)
CONFIG_FB_DA8XX video driver... Not the new fancy CONFIG_DRM_TILCDC
we've been using since 3.8, that has edid/etc working.. yuck..

So, here's the patches/hacks i used to get it to build:

Hi Robert,

Thank you so much for all your help.

Yeah, this is just crazy. I had no idea these kernels where so different.
Some of us have been trying to get SGX working on V3.8 because we need
Xenomai support and I just learned [1] that the only 3.8 kernel that works
with SGX is TI V3.8.y kernel or the Yocto [2] kernel (I going to patch and
build to confirm). Patching your 3.8.13-bone31 kernel doesn’t work. My
guess is I need these same patches in V3.8?

Really the Yocto 3.8 works too? it's 99% the same patch as my 3.8

Hi Robert,

Not necessary. Your V3.12 is booting via NFS. Just needed to enable
CONFIG_ROOT_NFS =y. I’m surprised that more developers don’t use NFS. I
can make all the file changes directly on my desktop and simply hit the
reset button and viola I’m up and running. No need to program SDCards.
Also, I have my targetNFS automated backup every hour so if I get into
trouble, I can got back to a previous version in seconds.

BTW, when the kernel is configured for Initrd, NFS doesn’t work, so I was
wondering why your kernel is configured to use Initrd. Is this really
necessary?

We need it to support the Netinstall.

The debian-installer is contained within in a custom initrd, that we
run at startup, which is then used to create the rest of the root
disk..

Good to know.

BTW, good news is SGX is working on your kernel. I can run the 3D demos
under /opt/gfxsdkdemos/ogles2.

I¹m using 3.12.5-bone.4
