Solve AVRdude Stk500v2_getsync() Error on Selected Serial Port

Are you a programmer trying to solve AVRdude Stk500v2_getsync() error on your selected serial port? This tutorial will teach you how to debug and fix the issue with step-by-step instructions you can follow.

Overview

AVRdude is a program used to burn programs and read/write data to/from an Atmel AVR microcontroller. AVRdude can also be used for other tasks as well such as loading a HEX file onto a chip or verifying the contents of a chip. However, you may run into an AVRdude Stk500v2_getsync() error when trying to burn a program to your AVR microcontroller. This can be an annoying problem and is difficult to debug, but luckily, there are some tips and tricks you can try to resolve it.

Troubleshooting AVRdude Stk500v2_getsync() Error

Try A Different USB Port

The first thing to try when troubleshooting the AVRdude Stk500v2_getsync() error is to try plugging the USB cable into a different port. This sometimes resolves the issue as the port you are using might be slow or faulty.

Check For Updated Chipset Drivers

If the previous step did not solve your issue, check to see if your computer has the latest drivers for the chipset. Outdated drivers can cause issues with the port, so it’s worth checking this. Depending on your operating system, the chipset drivers can be found in different places. For example, in a Windows-based system, you can find them in the Device Manager.

Check For Updated Programmer Drivers

In some cases, the issue might be due to outdated programmer drivers. This is especially true for USBasp programmers. If this is the case, you may need to update the drivers for your programmer. You can usually find the latest drivers for AVR programmers on the internet.

Check For Firmware Updates

You should also make sure that your programmer has the latest firmware. In many cases, the AVRdude Stk500v2_getsync() error can be caused by outdated firmware versions. Make sure to check the manufacturer’s website for any updates to the firmware.

Re-Flash The Firmware

In some cases, the AVRdude Stk500v2_getsync() error can be caused by corrupted firmware. If this is the case, you can try re-flashing the firmware with an updated version. This is quite simple if you are using a USBasp programmer. All you need to do is download the latest version of the firmware and use AVRdude to flash the firmware to the programmer.

Try All Connection Pins

Lastly, if all of the above steps fail, you can try connecting the programmer to different pins on the microcontroller. For example, if you are using an AVR microcontroller, you can try connecting the programmer to pins such as VCC, PD0, RESET, and so on. Doing this should help narrow down the issue and can occasionally fix the AVRdude Stk500v2_getsync() error.
