Not what you want to hear but. Simple solution is to get a Raspberry Pi. NanoDLP was made to run on Raspberry. And normal pc's second.

I did not expect it even run on pcDuino1. Enable framebuffer on the setup page see if it helps.
You should use generic arm version. It will be enough to just replace binary called printer

I Enable framebuffer and i have the same results,
with fbi framebuffer i can display a jpg or png from console.
nanodlp use GLFW/OpenGL, maybe need to be installed on the pcDuino1 ??

Again i have glfw 3.0.4 installed and opengl too but the same error message.

No, on ARM version it use framebuffer only which does not require opengl.
It is better to use ubuntu server version as desktop could cause issue with ARM version.

yes we use server version, the framebuffer work on my console perfectly using fbi.
in nanodlp is crach with framebuffer too.
