# From: https://github.com/letscontrolit/ESPEasy/blob/mega/tools/pio/post_esp32.py
|
||||
# Thanks TD-er :)
|
||||
|
||||
# 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
|
