- Connect using external USB - UART converter: ground, 5V, RX, TX
- Connect D3 (flash) to ground
- To erase:
python3 -I ~/.arduino15/packages/esp8266/hardware/esp8266/3.0.2/tools/esptool/esptool.py -p /dev/ttyUSB0 --chip esp8266 --before no_reset --baud 74880 --trace erase_flash- To flash, use Arduino IDE, set baud rate to 115200
- Click upload in IDE
- Press reset
- Wait until flash is complete. D3 can remain connected to ground (but should not be necessary).
Minimal config to flash bare esp8266 module:
- Gnd
- Vcc
- pull up Enable / CH_PD
- pull down Flash (GPIO0)
- pull down GPIO15
- Connect via ground, rx, tx
