Flashing a 1MB ESP-01

Posted on
  • I've got some ESP-01's here that I'd like to put esprunio on they're a 1MB board according to esptool:

    esptool.py v3.3-dev
    Serial port /dev/tty.usbserial-220
    Detecting chip type... Unsupported detection protocol, switching and trying again...
    Detecting chip type... ESP8266
    Chip is ESP8266EX
    Features: WiFi
    Crystal is 26MHz
    MAC: a4:cf:12:c9:1f:ab
    Uploading stub...
    Running stub...
    Stub running...
    Manufacturer: 5e
    Device: 4014
    Detected flash size: 1MB
    Hard resetting via RTS pin...

    Can someone advise on the command I'd need to flash them with and if I can use files from the published builds, (I don't really want to get into setting up a build environment for these) Can I use (some of ) the files in https://www.espruino.com/binaries/esprui­no_2v11_esp8266_4mb/ with a different map?

  • Thanks that worked, I had to set —flash_size 8m as well but that makes sense.

    And the mode to dout for these boards.
