I already said I've had it working on iMX6 - this was with both a yocto image and with QNX (both ES2). The Tegra K1 works with its out of the box image once you build Qt for it - which you can even do in situ once you enable some swap space! I also know the guys at TQC have it running on boot2qt images even with a <1sec boot time. > Qt3D is a great project for non embedded devices.

Qt 3D works fine on ES 2. The issue is the GLSL compilers in some of the binary blob drivers. But you will hit the same issues even if using pure ES2 vs Qt 3D. Yes we could try to work around the compiler issues by providing modified shaders for these but it's a pain. I've asked for someone here to try to locate a rasp pi 3 and see what needs fixing there. It's purely shader issues. There's nothing fundamentally wrong we're doing for ES 2 support.
