espflash

espflash is a serial flasher utility designed for Espressif SoCs and modules. It natively supports all chips compatible with esp-hal.

Installation

To install espflash, execute the following command:

cargo install espflash --locked

Alternatively, you can use cargo-binstall to download pre-compiled artifacts from the releases and use them instead:

cargo binstall espflash

Note

The default baudrate used by espflash is 115200 - you might want to increase it to make flashing faster. The easiest way to do that is setting the ESPFLASH_BAUD environment variable.
