Esptool

Утилита esptool - загрузчик Flash памяти для микроконтроллеров ESP8266. Для Linux существует версия esptool на Python и в виде скомпилированной программы.

Установка esptool.py:

pip install esptool

Copy

Установка esptool в Linux Ubuntu:

sudo apt install esptool

Copy

Запускаем esptool:

esptool.py

usage: esptool [-h] [--chip {auto,esp8266,esp32}] [--port PORT] [--baud BAUD]

[--before {default_reset,no_reset,no_reset_no_sync}]

[--after {hard_reset,soft_reset,no_reset}] [--no-stub]

[--trace] [--override-vddsdio [{1.8V,1.9V,OFF}]]

{load_ram,dump_mem,read_mem,write_mem,write_flash,run,image_info,make_image,elf2image,read_mac,chip_id,flash_id,read_flash_status,write_flash_status,read_flash,verify_flash,erase_flash,erase_region,version}

Проверим связь с микроконтроллером:

Подключаем ESP8266 модуль к компьютеру, например так ESP8266-01 подключение USB-UART. Запускаем тест. В нужный момент зажимаем кнопки RESET и Prog, отпускаем сначала RESET затем Prog:

esptool chip_id
