esptool-legacy-flasher-stub

This repository is deprecated.

Development has moved to esp-flasher-stub. That project is the supported replacement for this legacy flasher stub and will receive ongoing maintenance and new chip support from Espressif.

Do not start new work here. For bug fixes, features, and new targets, use esp-flasher-stub instead.

About this project

This repository contains the original flasher stub that was extracted from esptool. The stub is a small program loaded into chip RAM during flashing. It provides faster flash operations and features beyond what the ROM bootloader offers.

It is kept available for reference and for users who still depend on the legacy implementation. It is not actively developed and will not receive official support from Espressif.

How To Use

1. Install esptool in development mode.
2. Obtain the flasher stub binaries as JSON files either from the releases page or from the artifacts of your pull request.
3. Replace the esptool's JSONs files in the esptool/targets/stub_flasher directory with the obtained JSON files.
