If we analyse what the arduino IDE is doing when uploading a binary:
C:\Users\Florian\AppData\Local\Arduino15\packages\esp32\tools\esptool_py\2.6.1/esptool.exe --chip esp32 --port COM4 --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0xe000 C:\Users\Florian\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.2/tools/partitions/boot_app0.bin 0x1000 C:\Users\Florian\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.2/tools/sdk/bin/bootloader_dio_80m.bin 0x10000 C:\Users\Florian\AppData\Local\Temp\arduino_build_47342/main.ino.bin 0x8000 C:\Users\Florian\AppData\Local\Temp\arduino_build_47342/main.ino.partitions.bin
We can see that it flash several binaries:
- boot_app0.bin 0xe000
- bootloader_dio_80m.bin 0x1000
- main.ino.bin 0x10000
- main.ino.partitions.bin 0x8000
If we use the flash download tool from espressif:
And set the parameters used by arduino IDE, we are able to upload to ESP32 a binary file containing OpenMQTTGateway.
Once done yo should see the followig scree:
Note that I have uploaded the required binaries in the zip file.
