buildroot OpenGL flickering on N2

Post by brianli903 »

I compiled a buildroot image following the instructions below.
https://wiki.odroid.com/odroid-n2/softw ... _buildroot

After booting the box, I run OpenGL sample binaries (e.g. /usr/share/arm/opengles_2.0/cube/cube) .
The animation is flickering. Looks like it's displaying alternative frames only (frame 1->3->5...).

Any potential reason causing this? HDMI resolution output issue or gfx/Mali driver issue?

Buildroot is not have been tested recently due to very less demand while Linux kernel 4.9.y branch is hugely grown up, but it should work...let me try it out. HDMI resolution is not a matter, but I suspect if a decent Mali driver is being copied.
