QT 5.9 IMX 6 dual plus yocto/openembedded build questions

Wed Sep 27 22:17:09 UTC 2017

I have a working custom board that has been running kernel 4.1 and the
proprietary vivante drivers.  We would like to migrate to kernel 4.9 or
later and are therefore moving to etnaviv drivers.

This is a no X11 and no wayland on this embedded display.

When I try to run the app I get the following output with the "./app
-platform eglfs"

root at ppdisplayimx:~# ./app -platform eglfs
QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open
failed
QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open
failed
[default] QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to
'/tmp/runtime-root'
[qt.qpa.egldeviceintegration] Failed to load EGL device integration
"eglfs_viv"
[default] EGL library doesn't support Emulator extensions
Aborted (core dumped)
root at ppdisplayimx:~#

Please help me understand what I am missing in order to get the app to run
with etna drivers on this system?  Thank you.

I believe I have the kernel configured correctly I get psplash to display
my splash screen. dmesg provides the following

root at ppdisplayimx:~# dmesg | grep -i etna

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into
'/home/build/ppdev/bakery/gen3/oe-imx-summer/build/tmp-glibc/work/armv7ahf-neon-imx-oe-linux-gnueabi/qtbase/5.9.0+gitAUTOINC+f6b36eaafe-r0/recipe-sysroot/usr'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.
