Go Cross Compilation Raspberry Pi

notes.md

The linux/arm and linux/arm64 targets will cover most Raspberry Pi models, but you need to set GOARM properly when targeting 32-bit ARM devices.

Mapping Raspberry Pi Models to Go Architectures

Raspberry Pi Model	Go Architecture
Raspberry Pi 1 (A, B, A+, B+), Zero, Zero W	GOARCH=arm GOARM=6
Raspberry Pi 2 (v1.1)	GOARCH=arm GOARM=7
Raspberry Pi 2 (v1.2), 3, 3+, CM3	GOARCH=arm GOARM=7
Raspberry Pi 4, 400, CM4 (32-bit OS)	GOARCH=arm GOARM=7
Raspberry Pi 4, 400, CM4 (64-bit OS)	GOARCH=arm64
Raspberry Pi 5 (64-bit OS)	GOARCH=arm64

Cross-Compiling for Specific Raspberry Pi Models

• Raspberry Pi Zero / Zero W / 1:

  GOOS=linux GOARCH=arm GOARM=6 go build -o myprogram-pi0

• Raspberry Pi 2 (v1.2), 3, 3+, CM3, Pi 4 (32-bit OS):

  GOOS=linux GOARCH=arm GOARM=7 go build -o myprogram-pi3

• Raspberry Pi 4, 400, CM4, Pi 5 (64-bit OS):

  GOOS=linux GOARCH=arm64 go build -o myprogram-pi4

Key Takeaways

• GOARCH=arm is for 32-bit ARM systems.
• GOARCH=arm64 is for 64-bit ARM systems.
• GOARM=6 is required for older ARMv6-based Pis (Pi Zero, Zero W, Pi 1).
• GOARM=7 is required for ARMv7-based Pis (Pi 2 v1.2, Pi 3, 3+, CM3).
• No GOARM is needed for GOARCH=arm64.
