i use yocto morty with kernel 4.1.38-fslc+gee67fc7e072d  with kernel arguments:

setenv mmcargs "setenv bootargs console=${console},${baudrate} root=${mmcroot} video=mxcfb0:dev=ldb,disp,if=RGB24,bpp=32 video=mxcfb1:dev=hdmi,1920x1080M@60,if=RGB24 fbmem=48M lpj=30000"

 

I use Qt 5.6.2 and enable HDMI with echo 0 > /sys/class/graphics/fb2/blank

then export QT_QPA_EGLFS_FB="/dev/fb2"

and run my app with ./myApp -platform eglfs -style material

but i get error ( EGL Error : Could not create the egl surface: error = 0x3003)

if i use fbtest on hdmi (/dev/fb2) it will work okay!!! 

i dont know what is problem!

Note: if I enable LVDS and HDMI separately they work fine, but if I enable both of them simultaneously I will get this error!!!

Hi moh

this bsp is not supported by nxp, it is supported by community so

may be posted on meta-fsl-arm mailing list, so that someone familiar with it could try to assist you.
https://lists.yoctoproject.org/listinfo/meta-freescale
Alternatively one can try nxp releases described on

i.MX 6 / i.MX 7 Series Software and Development Tool|NXP 

for example refer to attached Linux Guide, sect.sect.4.7 Running Linux OS on the target

Best regards
igor
