1) <b>flash the init data</b> | |||
Following from https://nodemcu.readthedocs.io/en/master/en/flash/ : <br> | |||
If you need to customize init data then first download the Espressif SDK 2.0.0 and extract esp_init_data_default.bin. Then flash that file just like you'd flash the firmware. The correct address for the init data depends on the capacity of the flash chip. | |||
0x7c000 for 512 kB, modules like most ESP-01, -03, -07 etc. | |||
0xfc000 for 1 MB, modules like ESP8285, PSF-A85, some ESP-01, -03 etc. | |||
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) <b>flash actual working firmware:</b> <br> | |||
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. | |||
