#56396 I am a Newbie using Arduino 1.6.12 and loving many successful uploads to the cute WeMos D1 mini. I even had a web server working over WiFi, and the OLED display clock working.
However, after a few hours, they all suddenly stopped working at upload time and I got an extra error in orange that reads: "Uploading 226144 bytes from C:\Users\DELLUS~1\AppData\Local\Temp\arduino_build_886677/sketch_oct11a.ino.bin to flash at 0x00000000" and when the Blue LED stops flashing nothing happens....no successful load.
This now happens on all sketches, even the startup Arduino blank outline sketch. I even tried a brand new D1 mini. I am using a Dell inspiron 64 bit PC with Windows 10 and all the updates.
I have seen a similar loading error message issue listed elsewhere where the article said the bootloader esptool should be replaced by the newer esptool.py to solve the static memory allocation issue....but I can't find any step by step method to actually install this on Win 10. I even installed Python 2 to try to load it automatically. I am not good enough to understand how to follow the instructions at https://github.com/themadinventor/esptool as they may not be for a PC with Win 10.
Any suggestions....anyone? Any help with my newfound hobby would be appreciated.

#56412 False alarm on this error. Newbie mistake. The so called "error code" I quoted above appears to be a statement in the Arduino IDE of where the assembled code is coming from on my laptop and not an error message.
In fact the programs were loading and working and 'appeared' not to be working as my WeMos OLED display remained dark after working well for hours. Still not sure why it stopped.....but....
It turns out all my other programs were loading and working well....and after adding an Adafruit library, my little 64 X 48 pixel OLED display started working again as well.
Thanks for the great forum to assist me in my newfound hobby.
