The solution was to reconfigure as follows:./configure -platform linux-tinkerboard-g++ -eglfs -qpa eglfs -release -opengl es2 -nomake tests -nomake examples -opensource -confirm-license -v
And although the HelloGL2 / 3 examples now work fine, when the application starts (and it always runs on the full screen), the X server stops (or minimizes), you have to exit the system and run it in terminal manually. Perhaps this is fixable, but use it with VNC not possible. Also the frame rate in example HelloGL3 quite small. Perhaps the performance can be increased on this board by increasing the GPU frequency in the board settings (You can find the topic on the forum of this board how to do this) but apparently the automatic frequency control does not work here which will probably lead to more power consumption and heating.
