Playground of RaspberryPi baremetal.

What is a baremetal?

The baremetal means not using linux or some OS. Build with scratch to alls. One of the exception I believe VideoCore4 has such an OS on firmware or something.

Requirement

• Raspberry Pi Zero W or such devices.
• Ubuntu (latest)
• Arm compiler sudo apt install gcc-arm-none-eabi
