• Outputs specify file format:
  • llgo build -target esp32 -o hello [-obin, -oimg, -ohex, -ouf2, -ozip]
• Run on emulator:
  • llgo run -target esp32 -emulator
• Run and monitor on device:
  • llgo run -target esp32 -port /dev/cu.usbserial-110
• Install on device:
  • llgo install -target esp32 -port /dev/cu.usbserial-110
• Show logs and panic address:
  • llgo monitor -target esp32 -port /dev/cu.usbserial-110
• Refactor link, convert, run, monitor workflow
  • Fix llgo run output to GOPATH/bin
  • Convert elf to esp32 hex when binary-format is "esp32*", otherwise intel hex
  • Auto scan serial 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 (ELF)
llgo build -target esp32 -obin -oimg.            # -> hello.elf, hello.bin, hello.img
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 (just workflow)
llgo test -target esp32 -emulator .              # run tests in emulator (just workflow)
llgo cmptest -target esp32 -port /dev/ttyUSB0 .  # run tests on device (just workflow)
llgo cmptest -target esp32 -emulator .           # run tests in emulator (just workflow)
llgo install -target esp32 -port /dev/ttyUSB0 .  # flash to specific port
llgo monitor -target esp32 -port /dev/ttyUSB0 .  # show logs and panic address
