If you are a developer working with microcontrollers, you may encounter "avrdude: butterfly_recv(): programmer is not responding" error. This error indicates that the programmer is not responding to the avrdude software. In this guide, we will discuss the causes of this error and provide a step-by-step solution.
Causes of "avrdude: butterfly_recv(): programmer is not responding" Error
There are several causes of this error. Some of the common causes are:
- Incorrect wiring of the programmer
- Incorrect configuration of the programmer
- Faulty programmer
- Incorrect fuse settings
- Low power supply to the microcontroller
Follow the steps below to fix "avrdude: butterfly_recv(): programmer is not responding" error:
Step 1: Check the Wiring
The first thing you need to check is the wiring of the programmer. Make sure that the connections are correct and secure. You can refer to the datasheet of the microcontroller to check the pinout and wiring diagram.
Step 2: Check the Configuration
Check the configuration of the programmer. Make sure that the programmer is configured correctly. You can refer to the datasheet of the programmer to check the configuration settings.
Step 3: Check the Programmer
Check the programmer for any faults. You can use a multimeter to check the continuity of the connections. If there are any faults, replace the programmer.
Step 4: Check the Fuse Settings
Check the fuse settings of the microcontroller. Make sure that the fuse settings are correct. You can refer to the datasheet of the microcontroller to check the fuse settings.
Step 5: Check the Power Supply
Check the power supply to the microcontroller. Make sure that the power supply is sufficient. If the power supply is low, you may encounter this error.
