Question
I'm encountering an error while trying to debug my application in Tizen Studio. The application launches successfully, but debugging fails with the following error:
Cannot launch application with GDBClient.
Error in final launch sequence
Failed to execute MI command:
-target-select remote 127.0.0.2:26102
Error message from debugger back end:
127.0.0.2:26102: Operation timed out.
127.0.0.2:26102: Operation timed out.
I've tried following the normal debugging steps and attached debugging instructions from the Tizen documentation, but the issue persists. The problem appears to be related to the remote address and port configuration. I've attempted using different port numbers (26100, 26101, 26102), but the port keeps changing back to 26102 automatically.
Could anyone help resolve this debugging issue?
Answer
Problem Understanding
The error occurs when Tizen Studio fails to establish a connection with the debugger due to port-related issues. The timeout suggests either:
- The specified port is blocked or in use
- There's an IP address misconfiguration
- The Tizen Studio installation might have issues
Solution Methods
-
Port Configuration Check:
- Verify the IP address matches your device's actual IP
- Try using static port numbers (26100-26102 range is standard)
- Ensure no other applications are using these ports
-
Firewall and Network Settings:
- Check your firewall settings to ensure debugging ports aren't blocked
- Verify network connectivity between your development machine and target device
-
Tizen Studio Reinstallation:
- Uninstall and reinstall Tizen Studio in a different directory
- Ensure you're using the latest version (updating to Tizen Studio 2.2 resolved this issue for the original poster)
Additional Tips
- Keep your development environment and target device physically close to minimize network issues
- Regularly update Tizen Studio to benefit from bug fixes and improvements
- For comprehensive debugging guidance, refer to the official documentation at Samsung Tizen OS Debugging Guide
