I just purchased the new Raspberry Pi 3 Model A+ below and thought it would work right away as it is identical to B+ except for no Ethernet port and a single USB port. However, I tried with the current RPI image and it did not boot up. I then tried NOOBS and it worked fine except installing Librelec from NOOBS menu did not work either. Raspbian worked fine.
Raspberry Pi 3 Model A+ - Raspberry Pi
Is it possible to add support for this device?
