I am trying to flash a new Firmware to my Ender 3 Pro.

I am using the ESP8266 as an ISP via AVRISP over Wifi.

I have a 10mF capacitor between the ground and reset of the ESP8266

I followed this thread: ESP8266 as ISP program for ATMega16

When uploading I get the following output on console:

avrdude done.  Thank you.

I can't seem to get it to work. Does anyone have any ideas?

I tried programming it directly: I use the standard Arduino ISP sketch on my ESP8266 and try to upload that way. Directly connected the ESP8266 to my computer. I get sync-problems now: avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x61 The Board in the arduino IDE is set to Sanguino 1284p and the programmer is set to Arduino as ISP.

  • I have a 10mF capacitor between the ground and reset of the ESP8266. I'll edit that info in the question as well. Commented Sep 14, 2019 at 21:36

  • That goes beyond my understanding. I changed plans though. I use the standard Arduino ISP sketch on my ESP8266 and try to upload that way. Directly connected the ESP8266 to my computer.

  • you are not alone github.com/esp8266/Arduino/issues/6517#issuecomment-531480035 I will try it today. I tested it in Jan 2018 and it worked then Commented Sep 15, 2019 at 5:27

I assume that you have to wrap the directory in the option -U flash:w:C:\Users\Chry\AppData\Local\Temp\arduino_build_166520/TH3DUF_R2.ino.hex:i with "s. I don't promise that it'll work with that change, but C:\Users... will definitely confuse the parser due to the :!
