How to make:

1. install "arm-none-eabi-gcc".
2. Open "Makefile " with texteditor, and change options.
   BOARD=RPZERO/RP1/RP2/RP3
3. make
4. If successfully, output "kernel.img"(RPZero/1) or "kernel7.img"(RP2/3).

How to run:
Put follow files to FAT SD card.

• "bootcode.bin"
• "start.elf"
• "config.txt" <- config_rp01.txt or config_rp23.txt
• "kernel.img"(RPZero/1) or "kernel7.img"(RP2/3)

Firmware:
Grub "bootcode.bin" and "start.elf" at
https://github.com/raspberrypi/firmware/tree/master/boot
