Hi everyone Please help me in case below. I see this video <https://www.youtube.com/watch?v=tjlpeXoUp48> on youtube which is showing that Boot2Qt is working on NXP WaRP7 with QTLite 5.8
I 've bought WaRP7 & its LCD display but I can not make it work (display something on screen). Sorry for my noob question: - how can I made a sample exactly the same in video ? - I try many ways but failed, since I'm just dive in embedded only for 2 months and still don't know where to start. It is many thanks if anyone can figure out is there any problems with any my solutions below ? I tried to use Boot2Qt in Qt 5.9.2, 5.10 & build Wearable example on it. When I run sample, there is nothing display but only error on command line 1st try: run commandexport QT_QPA_PLATFORM=linuxfb export QMLSCENE_DEVICE=softwarecontext /data/user/qt/wearable/wearable => command line is running and show like application is running (compare with sample on raspberryPi3) but nothing display 2nd try:run only /data/user/qt/wearable/wearable => error show: QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root' Could not open egl display Aborted(code dumped) 3rd try: I used fsl-multimedia BSP of Yocto project to boot on my WaRP7. I run command "export DISPLAY=localhost:0.0" & execute application => There is no error. I try to find resolution by command "xrandr -q" => error: error message: Can't open display localhost:0.0 4th try: I used QtLite 5.8 with Yocto build (bitbake core-image-base & core-image-sato). But no hope as well. Other tries: I try to use fbtft driver to drive LCD, also try to boot display via SPI and many other configuration for weeks. But display still BLACK :( Thank you for your reading time. Note: sorry if my english confuse you.
