• I can confirm the peek stuff above works, however I get a reset with E.memoryArea trying to read the Esp8266 flash:

    >esp8266 = require("ESP8266");
    =function () { [native code] }
    >var base=esp8266.getFreeFlash()[2].area;
    =1011712
    >E.memoryArea(base,10);

    It works with the 0x3ff00054 address:

    >peek32(0x3ff00054).toString(16)
    ="20000d9"
    >E.memoryArea(0x3ff00054,4);
    >E.memoryArea(0x3ff00054,4);
    ="\xD9\x00\x00\x02"
    

    So this seems to be associated with the address....
