Is it possible to “reformat” the esp8266? Absent mindedly I flashed a 1m bin to a 4m device. Now I can’t get it to accept 4m binaries, or rather they program but then crash right away. Tried several times to flash various other bins, some work some don’t. Maybe I just got a bad module.
What are you using to flash the bin file and how? They are cheap so I have a couple and also an esp32. I have used LUA on nodemcu and the arduino ide but am now working with the their development stuff to get more access to the guts of these cool toys. Never had any problem with flashing one.
There is cool web based BIN utility for LUA on nodemcu and John Lauer wrote an easy to use web based interface. Great way to learn esp stuff and way easier than setting up ESP-IDF.
@Steve_Anken I’m using the Arduino IDE and also Atom + PlatformIO … found a procedure to upload four 1M blank bin files to the chip, and then the AT firmware again. Seems to have done the trick.
Give following discussion a try: https://github.com/espressif/esptool/issues//213#issuecomment-310529902
It helped me sometime when I thought that I had bricked my ESP8266.
Strange, should not matter, I will read the post above and see what they say…
OK read it interesting… Never needed this info so never had chance to try it.
