I have a NodeMCU ESP12E DevKit V2 from Geekcreit. I had it working some months ago, but now I cannot upload to it. I am using the arduino IDE and I've set the "Additional Boards Manager URLs" to:
http://arduino.esp8266.com/stable/package_esp8266com_index.json
The error I get:
warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
What I've tried so far:
- Applying 3.3v to the VIN
- Uploading from 3 different PCs and one Ubuntu
- Uploading using Arduino IDEs: 1.6.18, 1.6.2, 1.6.9, 1.6.11
- Using the esptool.exe to upload to it from the cmd prompt.
- Using following board configurations from the Arduino IDE:
- "NodeMCU 1.0 (ESP-12E Module)"
- "NodeMCU 0.9 (ESP-12 Module)"
- "Generic ESP8266 Module"
- "NodeMCU 1.0 (ESP-12E Module)"
- Uploading with different upload speeds.
- Uploading with different flash sizes.
- Uploading with different USB cables.
- Tried erasing flash, read flash.
All of the above has still resulted in the error stated in the top of this post.
Verbose output from upload:
I was beginning to suspect that my NodeMCU board is broken somehow, but the old file is still uploaded on the device is active on my network, so if it is broken, it might just be the usb port.EDIT: Just received a new module that gives the same error, so it is not due to faulty hardware.
However, I have found people facing the same issues when googling, but no real solution has worked for me, and the above list of what I've tried is mostly suggestions found in this process.
I'm running low on ideas and I am thinking to order a new NodeMCU board to try and rule out flawed hardware.
Any suggestions or help will be much appreciated. Thank you.
