This repository contains patches that can be used to add Embedded Go supported architectures to the reference Go compiler.
The main way to install Embedded Go is to use precompiled binary packages. See embeddedgo.github.io/getting_started for download links.
The alternate way to try Embedded Go with the last (unstable) changes is to clone the github.com/embeddedgo/go repository.
Currently supported architectures:
| GOOS/GOARCH | Target |
|---|---|
| noos/thumb | ARMv7-M microcontrollers (i.MX RT, nFR52, STM32, ...) |
| noos/riscv64 | RV64G SOCs (tested on Kendryte K210) |
| linux/thumb | Linux on ARMv7-A (Cortex-A), Thumb2 ISA |
For GOARCH=thumb you can set GOARM=7 (default, hard float, requires 64-bit FPU) or GOARM=7,softfoat (no FPU or 32-bit FPU). The emgo tool infers a correct GOARM value for GOTARGET and has more useful feutures so use it instead of the raw go tool.
- Download the patch that matches your version of Go or the entire repository:
git clone https://github.com/embeddedgo/patch
- Download Go compiler:
git clone https://go.googlesource.com/go goroot
- Apply a patch and build the Go distribution:
cd goroot
git checkout go1.22.5
patch -p1 <../patch/go1.22.5
cd src
./all.bash
