Flags

  • -o <file> - Specify output file name
  • -target <platform> - Specify target platform for cross-compilation
  • -file-format <format> - Convert to specified format (requires -target)
    • Supported: elf (default), bin, hex, uf2, zip, img
  • -emulator - Run using emulator (auto-detects required format)
  • -port <port> - Target port for flashing or testing

Commands

llgo build

Compile program to output file.

  • No -target: Native executable
  • With -target: ELF executable (or -file-format if specified)

llgo run

Compile and run program.

  • No -target: Run locally
  • With -target: Run on device or emulator (equivalent to install + monitor)

llgo test

Compile and run tests.

  • No -target: Run tests locally
  • With -target: Run tests on device or emulator
  • Supports -emulator and -port flags

llgo install

Install program or flash to device.

  • No -target: Install to $GOPATH/bin
  • With -target: Flash to device (use -port to specify port)

Examples

# Native development
llgo build hello.go                              # -> hello
llgo build -o myapp hello.go                     # -> myapp
llgo run hello.go                                # run locally
llgo install hello.go                            # install to bin

# Cross-compilation
llgo build -target esp32 .                       # -> hello (ELF)
llgo build -target esp32 -file-format bin ,      # -> hello.bin
llgo run -target esp32 .                         # run on ESP32 (guess a port)
llgo run -target esp32 -emulator .               # run in emulator
llgo test -target esp32 -port /dev/ttyUSB0 .     # run tests on device
llgo test -target esp32 -emulator .              # run tests in emulator
llgo install -target esp32 -port /dev/ttyUSB0 .  # flash to specific port
