# Part of ESPEasy build toolchain.
|
|
#
|
|
# 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)
|
|
# Maintainer: Gijs Noorlander (@TD-er)
|
|
#
|
|
# Special thanks to @Jason2866 (Tasmota) 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 | ~\ESPEasy\.pio\build\<env name>\partitions.bin
|
|
# - 0xe000 | ~\.platformio\packages\framework-arduinoespressif32\tools\partitions\boot_app0.bin
|
|
# - 0x10000 | ~\ESPEasy\.pio\build\<env name>/<built binary>.bin
