TamaGo: Bare Metal Go for ARM SoCs— A framework that enables compilation and execution of Go apps on bare metal ARM System-on-Chip (SoC) setups (including the Raspberry Pi 2 and Zero so far). An ARM-only alternative to the more established TinyGo, potentially, as TamaGo modifies the standard Go distribution while TinyGo is a distinct LLVM-based compiler.
