cargo-espflash

ESP8266 and ESP32 cross-compiler and serial flasher cargo subcommand.

To build the project before flashing, cargo-espflash has a few options, specified with the --tool TOOL flag.

• --tool xbuild, build using cargo xbuild. Requires cargo xbuild installed on your system. This is the default option.
• --tool cargo, build using the build-std unstable cargo feature.
• --tool xargo, build using xargo. Requires xargo installed on your system.

Usage

$ cargo espflash [--ram] [--release] [--example EXAMPLE] [--chip {esp32,esp8266}] [--tool {{cargo,xargo,xbuild}}] <serial>

When the --ram option is specified, the provided ELF image will be loaded into ram and executed without touching the flash.

Config

You can also specify the serial port or build tool by setting it in the config file located at ~/.config/espflash/espflash.toml or linux or %APPDATA%/esp/espflash/espflash.toml on windows.

[connection]
serial = "/dev/ttyUSB0"

[build]
tool = "cargo"

Example

$ cargo espflash --release --example=blinky /dev/ttyUSB0
