# From: https://github.com/letscontrolit/ESPEasy/blob/mega/tools/pio/post_esp32.py
# Thanks TD-er :)
# Thanks @staars for safeboot and auto resizing LittleFS code and enhancements
# Combines separate bin files with their respective offsets into a single file
# This single file must then be flashed to an ESP32 node with 0 offset.
#
# Original implementation: Bartłomiej Zimoń (@uzi18)
#
# Special thanks to @Jason2866 for helping debug flashing to >4MB flash
# Thanks @jesserockz (esphome) for adapting to use esptool.py with merge_bin
#
# Typical layout of the generated file:
# Offset | File
# - 0x1000 | ~\.platformio\packages\framework-arduinoespressif32\tools\sdk\esp32\bin\bootloader_dout_40m.bin
# - 0x8000 | ~\Tasmota\.pio\build\<env name>\partitions.bin
# - 0xe000 | ~\.platformio\packages\framework-arduinoespressif32\tools\partitions\boot_app0.bin
# - 0x10000 | ~\.platformio/packages/framework-arduinoespressif32/variants/tasmota/\<env name>-safeboot.bin
# - 0xe0000 | ~\Tasmota\.pio\build\<env name>/firmware.bin
# - 0x3b0000| ~\Tasmota\.pio\build\<env name>/littlefs.bin
