  I just managed to flash drazzy's bigram firmware and now my Espruino classic is working fine...

  I've just used the stm32loader tool to 1) erase and then 2) write the latest firmware (espruino_1v92.1909_espruino_1r3.bin) that I downloaded yesterday, but the verification (-v) mode fails:

  python Dropbox/Espruino/stm32loader.py -p /dev/ttyACM0 -v ~/Downloads/espruino_1v92.1909_espruino_1r3.bin

  Am I using this right? is it meant to return these many differences? I'm attaching the log

  I'm in a similar position (blue-red leds dimly lit, unable to connect in normal mode). I've just measured between 3.3 and GND and got the expected voltage(3.29v). Espruino classic, Rev1.4b
  Just to add, this happened after I flashed v 1.92 over v 1.91. I faced an issue with 1.91 whereas the board would use an older version of the program, despite calling save() from the console.

• [SOLVED] Is there anyway to have a filesystem-like facility on ESP8266?
