Ok, Im not exactly a beginner, but I feel like one so here goes.
Have a B I'm using for a robot, setup w/ composite, everything works well.
Bought a B+ to program and the ONLY thing that will boot is KANOS.
Ive tried NOOBS,WHEEZY,PIDORA you name it.
Ive tried 3 different micro sd cards, 1 i even put in the B and it boots ok.
Im using a USB mouse, USB keyboard, wired ethernet, 2A PS and HDMI.
KANOS boots up, sets up no probs.
I use the recommended FORMATTER4 to set the card up then
Im using windiskimage32 to copy the image over.
I will admit I have NOT tried to use this w/ composite video, because thats not how I need it setup, and thats in anopther room.
Thinking of buying a pre loaded card, but hate to pay for what i can do myself (Ive only been using Linux full time for 10 years)
