The esptool.py detects it as ESP8285, but the 2MB external flash would suggest an ESP8266. Any Ideas?
Detecting chip type... ESP8266
Chip is ESP8285
Features: WiFi, Embedded Flash
Detected flash size: 2MB
Before playing around with the firmware, I wanted to backup the firmware. So I did a:
esptool.py --port /dev/ttyUSB0 read_flash 0x00000 0x200000 image.bin
The image appears to be fine. I can see some plausible plain text strings. I'm just unsure if I missed some internal flash of the ESP8285
