How to flash firmware

Use esptool in python to flash firmware on esp.
Press flash button and reset and then release first reset button to get in flash mode

0) erase flash

./esptool.py --port /dev/tty<SERIALPORT> erase_flash

1) flash the init data

   0x1fc000 for 2 MB
   0x3fc000 for 4 MB, modules like ESP-12E, NodeMCU devkit 1.0, WeMos D1 mini
   
    ./esptool.py -p /dev/tty<SERIALPORT> write_flash -fm dio 0x00000 <binaryname>.bin 
    
    Example:
    ./esptool.py -p /dev/ttyUSB0 write_flash -fm dio 0x3fc000 esp_init_data_default.bin 

2) flash actual working firmware:
If you build your firmware with the cloud builder or the Docker image, or any other method that produces a combined binary, then you can flash that file directly to address 0x00000.

Flashing the nodemcu cloud build on 4MB flash ESP8266 :
./esptool.py -p /dev/tty<SERIALPORT> write_flash -fm dio 0x00000 <binaryname>.bin

Flashing the nodemcu cloud build on 512 kByte flash ESP8266 :
./esptool.py -p /dev/tty<SERIALPORT> write_flash -fm qio 0x00000 <binaryname>.bin Also check out README file in zip for more information.


Old firmware:
Flash command für precompiled Firmware oben
esptool.py -p /dev/tty<SERIALPORT> write_flash 0x00000 0x00000.bin 0x10000 0x10000.bin or with newer versions of esptool (e.g. 0.4.6 on debian): esptool -ca 0x00000 -cf 0x00000.bin -ca 0x10000 -cf 0x10000.bin

How to flash .lua files

For people who enjoy GUIs:
Use ESPlorer tool. Its user friendly and powerful with integrated editor and lots of commands.
Supports NodeMCU and MicroPython.
Needs Java and works on all major PC Plattforms

If you like commandline tools:
Use for example the nodemcu-uploader: nodemcu-uploader -B 115200 upload *.lua

Beware: The tool will not tell you that lines are too long and can not be uploaded but instead throw some error messages you do not understand and exit... The solution is to remove the comments at the beginning of the file before uploading or split them up.

Todo

  • Add schematics of current setups for elektrinkkammerl and scannerraum
  • Add more doku on how to flash and import the scripts
  • Design a breakoutboard with standardized connectors for I-button, and relays
