Well, yeah that lib was made for some specific purposes but it is still possible to use it so the GPU draw pre-rendered CPU graphics, for static content only (and also for things that don't need a refresh every frames) it would be very fast. Anyway i successfully made a C OpenGL ES 2 + fbdev example...

Okay thanks, got it to run with : s5p6818-sd-friendlycore-xenial-4.4-arm64-20190128.img it seem i was using a very old image file. What did you mean by 2D code ? Specific features of the Mali chip ? Because if you have OpenGL ES you can basically do any 2D stuff. Anyway my plan is to port the OpenGL...

Well just tried but i have the same error as all my others tentatives : root@NanoPi-Fire3:~/mali-fbdev-stress-test-tools/deb/arm64/xenial# glmark2-es2-fbdev Error: eglInitialize() failed with error: 0x3001 Error: eglInitialize() failed with error: 0x3001 Error: main: Could not initialize canvas root...

Thank you, although does this use the GPU ? Looking at the CPU usage it seem it is heavy on it.

fbdev is pure framebuffer (no acceleration), no ? Or does it use directfb ?

Hello, how did you compile it for the Fire 3 ? All I get is a segmentation fault / display not found whenever i compile OpenGL ES stuff on the Fire 3.

Updated the design to Rev 5, the top part now cover all the screen parts so it look great and finished, with some painting this could look like a final product like a mini TV box or industrial monitoring screen or something, i have also fixed some slight bending issues on the top wall and top band (...

Hello, i have made a quality Nano PI NEO / NEO2 + 2'8 Matrix TFT enclosure, it is available here : https://pinshape.com/items/46665-3d-printed-nano-pi-neo-neo2-28-tft-enclosure There are 2 parts, 2mm thick walls, optimized for 3D printing, no screws, accessible push button and it look like an old TV...
