• I've been collecting strange ESP8266 boards, and got my hands on 2 of these:


    Flashing 4MB combined with --flash_size 4MB and 4MB-c1 works fine, the thing reboots, but I can never get an Espruino prompt at this point, 115200 baud or 9600.

    Manufacturer: c8
    Device: 4016
    Detected flash size: 4MB

    Anyone have one of these and successfully flashed?

  • Nevermind, works fine. I was attempting to use the SSD1306 I2C on D1 and D2, needs to be NodeMCU.D1 and NodeMCU.D2 (sda & scl) respectively, and the other ones seem to be the serial RX/TX pins, causing nonsense on the terminal.

    ./esptool.py --chip esp8266 --port /dev/ttyUSB0 write_flash -ff 20m -fm dio --flash_size 4MB-c1 0x0 espruino_1v95_esp8266_4mb_combined_4096.­bin
