I have an ROC-RK3328-CC RENEGADE Pi clone. It's supposed to be an almost 1to1 of the Pi 3B+. On Libre's website, they have different starter flavors of OS's for it, but I was wondering if anyone has been able to get Ubuntu MATE running on it? All I get is a black screen when trying to boot after flashing the OS with no blinking activity. I'm guessing the ROC has special drivers/firmware that has to be tended to before any old OS can be installed.
If anyone can help, it'd be great!
