Install the firmware

Flash ESP32

When flashing the ESP32 for the first time, you need to install a bootloader, partitionscheme and application loader:

esptool.py --port "COM1" erase_flash
esptool.py --port "COM1" write_flash 0x1000 bootloader_dio_40m.bin --flash_mode dio --flash_freq 40m
esptool.py --port "COM1" write_flash 0x8000 partitions.bin
esptool.py --port "COM1" write_flash 0xe000 boot_app0.bin

Change COM1 to the correct port on your computer.

then flash the actual firmware:

esptool.py -p "COM1" --baud 921600 write_flash 0x10000 d1-mini-esp32_ili9341_<version>.bin

or all previous steps in one long commandline:

esptool.py -p "COM1" --baud 921600 --before default_reset --after hard_reset write_flash --flash_mode dio --flash_freq 40m --flash_size detect 0x1000 bootloader_dio_40m.bin 0x8000 partitions.bin 0xe000 boot_app0.bin 0x10000 d1-mini-esp32_ili9341_<version>.bin

Flash ESP8266

Unlike the ESP32, for ESP8266 you only need one single .bin file:

Using Tasmotizer (Windows)

Using esp-tool.py

esptool.py -p "COM1" write_flash --flash_mode qio --flash_size 4m 0x0 d1-mini-esp8266_ili9341_<version>.bin

Change COM1 to the correct port on your computer and 4m to the correct size of the internal flash chip.
