ESP8266-01: Not able to upload sketch anymore
Posted: Sat Jul 14, 2018 5:17 pmHello,
currently I only have problems with my ESP 8266-01. Actually I don't even get one single successful flash anymore, where the code is working afterwards. I have a few situations and I will explain them in the following text, but first please have a look at my circuit for flashing the ESP8266-01: Link
I tried to follow this picture for the wiring: Wiring tutorial
As you can see I am using an external power source with a 1,5A power supply which should be enough for the WiFi-modul, I hope.
My usage of the circuit for flashing: Press Reset-button (further away from the modul on my setup). Press Flash-Button (closer to the modul on my setup). Release Reset-button (blue lamp flashes one time). Release Flash-button (I also have tried pressing the Flash-button for the whole flashing process, but it didn't help).
I am working with the Arduino IDE with the following settings: Settings
I tried to change some settings according to some people posting their settings. But none really worked well. I also tried different flash sizes.
Question: What flash size do I need to set in the Arduino IDE? Or in general, what settings should I use here?
Following some tutorials I noticed the ESPTool.py programm. I downloaded it and tried the erase_flash command which should help get the new sketch on there but it didn't help. Also I exported the .bin-file from my programm out of the Arduino IDE and tried to flash the ESP with the ESPTool.py write_flash, but after reaching 100% it just resulted in the second error I will be listing below.
I also have tried another ESP8266-01 modul because I was scared that I broke the first one, but it didn't help and I still get the same errors.
I used this sketch but also have tried others. This just seemed very simple and I can easiely verify that the code is working through the serial monitor:
Now to the problems:
Error during the flashing of the modul. This is just copied from the Arduino IDE and pasted here. This error occures randomly at any percentage during the flashing-process.
2. This error just occures after flashing the modul succeded. Here are some pictures.
As you can see the flashing went to 100% (See picture 1). But the board, is printing nothing in the serial monitor (also blue LED not flashing). Then I will reset the board to restart it and get the message in the picture 2.
By now I have no idea how to get these modules working. All links on google are marked as "allready clicked", so maybe somebody here can help me with my problems.
Thanks in advance and have a nice day,
Heenne
