• Yup, that was it. :(

    So now flash_id is working but read_flash is not...

    C:\Work\Development\ESP8266\esptool-1.3>­esptool.py -p COM5 -b 115200 read_flash 0 1024 test.bin
    esptool.py v1.3
    Connecting...
    Running Cesanta flasher stub...

    A fatal error occurred: Invalid head of packet ('\x13')

    I have changed the sizes in the script to the following as directed, but it appears that this is for writing the flash, not reading:

    # Maximum block sized for RAM and Flash writes, respectively.
    ESP_RAM_BLOCK   = 0x80
    ESP_FLASH_BLOCK = 0x80
    

    I really don't want to try write flash on this board since I don't want to screw up the only good one that I have. :)

    I'll get the ESP module soldered onto my "clone" and see where that leads me.

    Thanks again for your help.
