Interestingly I have quite a few of these M1's,. I bought some for work, and set them up, and they all work fine on everyday tutorials. As its been a while since I tested them, I just noticed the one I use at work has a 1080p screen, the one at home a 720p
I guess I must have downloaded and installed slightly different versions of debian. (I always use maker supplied versions)
What is a concern though is the 1080p refuses to compile my generic maze hunt project, complaining of a vague internal compiler error...that usually means an overheat in other SBC I had this on, causing a shut down...but it does have other causes, its just very hard to pin down.
The home 720p board however has no such issues and compiles and runs the demo in full screen.
I will look into this issue at a later date when I have time and report back on any findings.
Edit..(I hate confusion) I reflashed an SD with the latest debian which indeed is 1080p and re-configured for it. There is for sure some issue with the GCC taking a horrible amount of time and that may be the cause of an overheat/shut down, bit it did compile and build, however it refused to open a window or EGL context, so that needs more review..
Edit edit yup latest version of Debian is screwed, you get UMP: ump_arch_open() failed to open UMP device drive when you try to init EGL, thats something deep in the kernal I can't really fix, so for now avoid the later version of Debian and use the older one which is fine but low res. I'll ask FriendlyArm if they can fix it.
