Took delivery of my N2+ Yesterday (Sunday) - DHL working all days at the moment....
after a bit of stuffing around and a pointer from tobetter. My notes to install Ubuntu 20.10 with 5.10rc and panfrost on the device - http://ix.io/2G19
In reading your chewitt logs in the mainline, it seems this N2+ is really only just now being supported in mainline without the ARM mali binaries.
Looking forward to running up LE on this.need to get back to coding.
