Flashing ArduinoIDE .bin via Espressif ESP32 Flash Download Tool

[bfaliszek]

Hi, I have a sketch of the application in the ArduinoIDE. When uploading to ESP32 with the ArduinoIDE level everything works fine. I exported it as a .bin file. I would like to use an external application to upload a .bin file to a board. ArduinoIDE compiles it every time I try to upload the sketch. It takes over 1.5 minutes with my project. I have over 100 ESP32 boards for flashing, so it will take forever for ArduinoIDE.

Using the esptool.py --port COM4 write_flash 0x1000 my_app.bin command, the board does not flash correctly.

Espressif ESP32 Flash Download Tool also doesn't work properly.

Any idea how I could flash my ESP32 with .bin file from ArduinoIDE?

Hardware:

Board: ESP32 Dev Module
Core Installation version: 1.0.4
IDE name: Arduino IDE
Flash Frequency: 40Mhz
PSRAM enabled: no
Upload Speed: 115200
Computer OS: Windows 10

0x1000 is not correct address, it should be 0x10000 for normal arduino app.

Go into File->Preferences. There is an option there to show verbose output during upload. Run an upload, and you will see the exact esptool command the IDE uses to upload your code.

0x10000 does not work - esptool.py --port COM4 -b 921600 write_flash 0x10000 FileFronArduinoIDE.bin
Only uploading via ArduinoIDE works. Output during upload:

If you go into File->Preferences in Arduino IDE, you can turn on verbose logging during upload. This will show you the exact command sent to esptool.

@lbernstone I have "verbose logging during upload" enabled, and the only thing ArduinoIDE displays to me is the information from the previous comment.

I don't know what version of the IDE you are using, but mine shows this info just above the output you show above:

Sketch uses 260377 bytes (19%) of program storage space. Maximum is 1310720 bytes.
Global variables use 95444 bytes (29%) of dynamic memory, leaving 232236 bytes for local variables. Maximum is 327680 bytes.

@lbernstone Thanks. It's helped. I must upload all 4 .bin files:
/esp32/tools/partitions/boot_app0.bin at 0xe000
/esp32/tools/sdk/bin/bootloader_qio_80m.bin at 0x1000
sketch.ino.bin at 0x10000
sketch_dec.ino.partitions.bin at 0x8000
