I have brand new Raspberry Pi Zero. I prepared an 32 GB SDcard with Raspbian Stretch Lite. I wrote the latest (Release date:2017-11-29,
Kernel version:4.9) image file with Etcher to the SDCard without any error.
My problem is that the Raspbian cannot start. I observe the rainbow screen, then I see the boot process log messages, but when the boot process is at the "Started Load/Save RF Kill Switch Status." the device always reboots.
I use 5V/2A power, HDMI, and keyboard only. I tried 2 SDCards, but the result is same.
Does somebody have an idea what could be the problem?
