Introduction
If you’re working with an ESP8266 or ESP32 microcontroller and have encountered the “error: espcomm_upload_mem failed” message, don’t worry. This error message is a common problem that occurs when uploading code to an ESP microcontroller.
What is espcomm_upload_mem?
Espcomm_upload_mem is a tool used to upload code to an ESP microcontroller. When this tool fails, it can cause the “error: espcomm_upload_mem failed” message to appear.
Why does it happen?
There are several reasons why this error message might occur. Some of the most common causes include: – Incorrect COM port selection – Incorrect board selection – Incorrect bootloader settings – Incorrect baud rate settings
Incorrect COM port selection
If you have multiple devices connected to your computer, you may have selected the wrong COM port. Make sure you have selected the correct COM port for your ESP microcontroller.
Incorrect board selection
Make sure that you have selected the correct board type in the Arduino IDE. If you select the wrong board type, you may encounter the “error: espcomm_upload_mem failed” message.
Incorrect bootloader settings
If you have modified the bootloader settings on your ESP microcontroller, you may need to adjust the settings in the Arduino IDE. Make sure that the bootloader settings match the settings on your ESP microcontroller.
Incorrect baud rate settings
Make sure that the baud rate settings in the Arduino IDE match the settings on your ESP microcontroller. If the baud rate settings are incorrect, you may encounter the “error: espcomm_upload_mem failed” message.
How to fix it?
There are several ways to fix the “error: espcomm_upload_mem failed” message. Some of the most common solutions include: – Restarting your computer – Disconnecting and reconnecting your ESP microcontroller – Checking your wiring – Updating your drivers – Reinstalling the Arduino IDE
Restarting your computer
Sometimes, a simple restart can fix the issue. Try restarting your computer and see if that resolves the problem.
Disconnecting and reconnecting your ESP microcontroller
Disconnect your ESP microcontroller from your computer and reconnect it. This can help reset the connection and resolve the issue.
Checking your wiring
Double-check your wiring to make sure everything is connected properly. A loose or broken wire can cause the “error: espcomm_upload_mem failed” message to appear.
Updating your drivers
Make sure that your drivers are up to date. Outdated drivers can cause issues with your ESP microcontroller and lead to the “error: espcomm_upload_mem failed” message.
Reinstalling the Arduino IDE
If all else fails, try reinstalling the Arduino IDE. This can help fix any issues with the software that may be causing the error message to appear.
Conclusion
The “error: espcomm_upload_mem failed” message is a common problem when working with ESP microcontrollers. However, with a little troubleshooting, you can easily fix the issue and get back to working on your project. Remember to double-check your settings, wiring, and drivers to ensure everything is set up correctly.
