The Raspberry Pi Zero W extends the Pi Zero family and it's also based on a BCM2835 SoC. Like the Pi Zero, it has 512MB RAM, Mini HDMI and USB On-The-Go ports. Both Pi's hasn't got Ethernet, but Pi Zero W has built in wireless LAN 802.11 b/g/n.

If I comment out alt3, it builds and boots okay. How to fix properly?
