guys, i have a sd mapper and i installed the bios and it only gives the log screen what could be the error? formatting the sd is in fat would be the wrong bios?
You have to build it from the repo. The v2 is not very common yet. Why there is no release / prebuilt ROM on the github makes no sense.
It seems you flashed only the base nextor file, the driver for your specific hardware is missing and needs to be added to the base nextor. I assume the _make.sh will take care of this.
